Array count

hi everyone,
i'm just new to programming and i need some help from everyone that is willing to help me.
what's the statement or code that's counting the values of an array?how can you do it?
lets say i got 6 arrays and each has a diferent integer value.how can i write the code for having the totalvalue of the array?...keeping in mind that also there is into a for statement .....???.....

lets say i got 6 arrays.....I hardly call this clearly defined. It seems the OP was simply using that as an example.
You should always write code that will work for all situations. What if the requirements were changed so that the array needed to hold 10 numbers, wrong answer calculated. Or worse if the array was < 6 numbers long, ArrayIndexOutOfBounds error. Or maybe the code needs to be dynamic ie the user enters a value for how many numbers are to be held in the array. All these will fail with your hard coded 6.

Can i use array.count in line?

All,
I have one small oracle program that take a ',' separated string as an input
and assigns the individual string to a nested table.
I am wondering if I can directly use array.count in my sql below
instead of assigning the count of the array 1st and then
using it.
l_cause_codes_array := util_pkg.tokenize_string(p_cause_codes_csv, ',');
l_count := l_cause_codes_array.count;
My current sql:
delete from po_complaint_cause p
where p.po_number = p_po_number
and p.comp_code = p_comp_code
and l_count > 1;
I would like to do something like:
delete from po_complaint_cause p
where p.po_number = p_po_number
and p.comp_code = p_comp_code
and l_l_cause_codes_array.count> 1;
I just want to reduce one context switch if possible.
Thanks.

Hi,
did it give an error? Did you try? But it is possible.
But why not the next code:
l_cause_codes_array := util_pkg.tokenize_string(p_cause_codes_csv, ',');
if l_cause_codes_array.count >1
then
    delete from po_complaint_cause p
    where p.po_number = p_po_number
    and p.comp_code = p_comp_code
end if;Do only the delete if it is bigger than 1, that is I think the fastest switch.

Need help for array counting

Any help for array question
Hello to All:
I want to tally or count some of the elements that I have in array but not sure how.
I have for example: int myArray[] = {90,93,80,81,71,72,73,74};My objective is to tally all of the 90's, tally all of the 80's and tally all of the 70's.
So, the result that I want to have would look something like the following:
System.out.println ("The total tally number of 90's is " 2 );
System.out.println ("The total tally number of 80's is " 2 );
System.out.println ("The total tally number of 70's is " 4 );I do not want to add these numbers, just want to count them.
Also I want to use a "forloop" to achieve the result intead of just declaring it at 2 or 4 etc..
Any help Thankyou

[u]First , This is not exactly what I have to
do for homework. There is a lot more, a lot more
involved with the program that I am working on.
Second, this is an example, an example, an
example of something that I need to achieve.
Third, you are asking for a code, to me that
sounds as if your asking for homework. Fourth,
I did not ask for any rude comments. Fith, in
the future please do not reply to my messages at ALL
if you can not help!!!!
Sixth, We did not ask for lazy goofs to post here.
Seventh, In the future please do not post here. Take a hike - there's the virtual door.

Help with arrays & counting characters in arrays

I am trying to figure out how to count how many times each characters appears in the array (but I have to do all the counts at once).
I am supposed to store the counts in an int[] array of 27 elements (26 letters & an extra count for everything else). How would I go about declaring the array, allocating it, & then setting each of the 27 elements zero?
Thanks so much the help.
public class CharCount {
     public static void main(String[] args) {
          new CharCount().process();
     public void process() {
         // This declares an array of char and then assigns it a value. The value comes from another one
         // of my secret programs.
         char[] countThese = Lab8.simple();
         printChars(countThese);
         for (int count =0; count < countThese.length; count++) {
          System.out.println(countThese[count]);
    // This method should print the characters in the array called print, one-by-one
    // Use a println ONLY after all the chars have been printed.
    public void printChars(char[] print) {
    public int charToInt(char ch) {
     if (ch >= 'A' && ch <= 'Z')
         return ch - 'A';
     else if (ch >= 'a' && ch <= 'z')
         return ch - 'a';
     else return 26;
}

I take it the charToInt method was given to you. If you don't know what it does, it will give you a value from 0 to 26 depending on what char you pass as a parameter. So if you pass an 'a' or an 'A' it will return 0, 25 for 'z' or 'Z' and 26 for anything else. You use this value to access an array an increment the value (the number of times that letter has occured.
int value = charToInt('a');
arr[value]++;
System.out.println("Number of a's = " + arr[0]);

Htmldb_application array count 0 when it shouldn't be

This was working until I made modifications to the application, i.e. tabs, menus and such. It uses a manually built tabular form - that part works and displays with correct values, but when I try to access the array with a loop it appears to be empty.
I also have an item P3_WHERE_CLAUSE that runs a similar loop to build a where clause for validation. I modified it to debug as shown below.
Any hints greatly appreciated - can't figure out how I broke it.
Here's the query for the tabular form:
select
htmldb_item.select_list_from_query(
1,key_id,
'select key_id, object_key from
val_object_key k,
VAL_OBJECT o
where o.object_name = :P3_OBJECT_NAME
and k.object_id = o.object_id') Key_id,
htmldb_item.select_list_from_query(2,object_key,
'select object_key, object_key from
val_object_key k,
VAL_OBJECT o
where o.object_name = :P3_OBJECT_NAME
and k.object_id = o.object_id') Key,
htmldb_item.text(3,'',50) Value
from VAL_OBJECT_KEY k,
VAL_OBJECT o
where o.object_name = :P3_OBJECT_NAME
and k.object_id = o.object_id;
Here's the code to save the page information (several items in a cascading form and then it loops to include values from the tabular form). The loop does not execute.
DECLARE P_KEY_ID NUMBER;
kvs_id NUMBER;
BEGIN
select prov_id.nextval into kvs_id from dual;
insert into key_val_set kvs_id values (kvs_id);
for i in 1..htmldb_application.g_f01.count
loop
insert into key_value (KV_ID,KEY_ID,KEY_VALUE,KVS_ID)
values
prov_id.nextval,
htmldb_application.g_f01(i),
htmldb_application.g_f03(i),
kvs_id)
end loop;
INSERT INTO PROV_INSTANCE
CLASS_ID,
SOURCE_ID,
DATE_OCCURED,
KVS_ID
VALUES
:P3_CLASS_NAME,
:P3_SRC_NAME,
:P3_DATE_OCCURED,
kvs_id
commit;
END;
Here's the test loop:
begin
:P3_WHERE_CLAUSE := 'begin test';
for i in 1..htmldb_application.g_f01.count
loop
:P3_WHERE_CLAUSE := 'where '||i;
end loop;
return :P3_WHERE_CLAUSE;
end;

Never mind - it was a page flow misunderstanding.

AppleScript Class recognition and Array count

I have an application "SolarMaxOsX" written in Obj C
This app is scriptable
I have a class named Ups and in Ups.m I have written following methods:

    self.upsDataListToDisplayInTable = [self fillUpsListDictionary];
    _uniqueID = [[NSUUID UUID] UUIDString];
    return self;
/* For appleScript recognition */

    return [[NSUniqueIDSpecifier alloc] initWithContainerClassDescription:appDescription containerSpecifier:nil key:@"Ups" uniqueID:self.uniqueID];
In AppDelegate.m:
There is an array : Upss declared as follows:
NSArray (Upss *) Ups; declared and initialised in AppDelegate.m file
self.Upss = [self initUpss];

Arrays - counting occurence

Hello everyone :)
A practical at college is requiring me to create a program that simulates throwing 3 dice a total of 5000 times and for it to tally the number of times that all possible answers have occurred. For example, with 3 dice the lowest you can get is 3 (three 1's) and highest, 18 (three 6's). Roll the three dice, see which of the 16 different outcomes (3-18) you have, and add 1 to the total number of occurrences that outcome has produced. After 5000 throws, I will need to see which outcome happened most often. I've been told I must use an array for counting the occurrences and it's the array part which is confusing me.
Implementing the 3 dice and a method that simulates them being thrown was easy but I just do not have a clue how to:
1) get it to be done 5000 times and
2) the outcomes be tallied
Heres the code I have so far..
import java.lang.Math;
public class ThreeDice
    public static int throwDie()
            double x = Math.random();
            double x2 = Math.random();
            double x3 = Math.random();
            x = (x * 6.0) + 1.0;
            x2 = (x2 * 6.0) +1.0;
            x3 = (x3 * 6.0) +1.0;
            int dice1 = (int)Math.floor(x);
            int dice2 = (int)Math.floor(x2);
            int dice3 = (int)Math.floor(x3);
            return dice1 + dice2 + dice3;
    public static void main(String args[])
    }the throwDie method has to be used in main method but I'm stuck as for what to do next I'm afraid.

Hello Looce and thank you for the welcome,
Using my (very limited) knowledge I've managed to get the first part done (roll the 3 dice 5000 times) and for now I've just set it to print all 5000 results and alas it indeed prints 5000 results.
The second part though I'm still stuck on, I was hoping google would be my savior but sadly not this time.
I should have probably said in my first post that I'm a complete beginner for Java but with it being used both this year and next year for college, I hope to be fairly skilled in the use of it one day :)
An update of the code:
import java.lang.Math;
public class ThreeDice
    public static int throwDie()
            double x = Math.random();
            double x2 = Math.random();
            double x3 = Math.random();
            x = (x * 6.0) + 1.0;
            x2 = (x2 * 6.0) +1.0;
            x3 = (x3 * 6.0) +1.0;
            int dice1 = (int)Math.floor(x);
            int dice2 = (int)Math.floor(x2);
            int dice3 = (int)Math.floor(x3);
            return dice1 + dice2 + dice3;
    public static void main(String args[])
            for(int i=0; i<5000; i++){
                System.out.println(throwDie());
    }

Ideas on transforming a byte array?

I'm writing a program to compress files - I read it in, transform it and then write it out again. I'm just having a little confusion with the transforming.
I'm keeping it as basic as possible and just starting with finding and replacing repeating bytes with an instruction of how many times the following byte is repeated. ie a a a a a = 5 a _ _ _
In order to do this I create a temporary array to write to (initialised to the same size as the input) and then check through for repetitions. If something is repeated more than twice (3+), then a marker byte is put in (I wanted to have specific ones for however many times the byte is repeated - within reason - which is the switch statement below), the next byte is the byte to be repeated and then I want to jump forward to the next different byte.
I then go through the temp array count the repetitions, create a new smaller byte array and write temp[] to output[] ignoring the bytes that are repeated.
This is what I have so far, but it doesn't quite do what I want:
public class Transformer {
     byte[] input;
     byte[] temp;
     byte[] output;
     byte rep;
     public Transformer() {
     public byte[] transform(byte[] in) {
          input = in;
          temp = new byte[in.length];
          output = new byte[count(input, temp)];
          output = compress(temp, output);
          return output;
     private int count(byte[] from, byte[] to) {
          int k = 0; // total bytes copied so far
          byte markerByte = (byte) 0xE1;
          for (int i = 0, j = 0; i < from.length; i = j) {
               for (j = i+1; j < from.length && from[j] == from[i] && j-i < 128; j++);
               if (j-i >= 3) {
                    to[k++] = markerByte;
                    to[k++] = (byte) (j-i);
                    to[k++] = from[j-1];
               } else {
                    to[k] = from[k];
                    k = i+1;
          return k;
        // (the following method isn't finished)
     private byte[] compress(byte[] from, byte[] to) {
          for (int i = 0; i < from.length; i++) {
               if (from[i] == (byte) 0xE1) {
                    System.out.println("repeat");
               System.out.println(from);
          return to;
     private byte getRepeatByte(int numberOfRepeats) {
          byte instruction;
          switch (numberOfRepeats) {
          case 1: instruction = (byte) 0xE1; break;
          case 2: instruction = (byte) 0xE2; break;
          case 3: instruction = (byte) 0xE3; break;
          case 4: instruction = (byte) 0xE4; break;
          case 5: instruction = (byte) 0xE5; break;
          case 6: instruction = (byte) 0xE6; break;
          case 7: instruction = (byte) 0xE7; break;
          case 8: instruction = (byte) 0xE8; break;
          case 9: instruction = (byte) 0xE9; break;
          case 10: instruction = (byte) 0xEA; break;
          case 11: instruction = (byte) 0xEB; break;
          case 12: instruction = (byte) 0xEC; break;
          case 13: instruction = (byte) 0xED; break;
          case 14: instruction = (byte) 0xEE; break;
          case 15: instruction = (byte) 0xEF; break;
          default: instruction = (byte) 0xE0; break;
          return instruction;
At the moment I'm using a marker byte in the transform() but I want to be using the switch statement to work out the right byte to put in first.
Does anyone have any advice on if I'm doing this in a ridiculous way or if my methods won't work.. As I haven't written a decompressor yet, it's pretty hard to test!

baftos - thank you for your advice, i will try that and see how it goes.
Jos - it is your method and thank you very much for it! It's part of an ongoing project of mine, which is turning out to be more challenging than i originally thought - when i posted on the other forum your loop did perfectly what I was trying to do at the time. I need all the advice i can get and hence post on multiple forums.

Arrays.equals doesnt seem to be working

Hi
i have an app that copys the contents of an object array into another, then reruns and compares its contents to the previous copy. they should be equal, but i get a not equal message. i have tried printing out the objects in a loop to see whats happening, i get this:
(code)
for(int i = 0; i < count; i++)
System.out.println(TestPcContainer);
System.out.println(TestPcContainerCopy[i];
output:
Thread[Thread-20,5,main] (orig element 0)
Thread[Thread-15,5,main] (copy element 0)
Thread[Thread-21,5,main] (orig element 1
Thread[Thread-16,5,main] (copy element 1)
Thread[Thread-22,5,main] (orig element 2)
Thread[Thread-17,5,main] (copy element 2)
i dont understand why i keep getting its not equal. i have copied the arrays using : System.arraycopy(TestPcContainer, 0, TestPcContainerCopy, 0, count);
and i compare by doing: if(Arrays.equals(TestPcContainer, TestPcContainerCopy)) { System.out.println("equal");}else not ......
thanx for any help on this

Error with declaring a method with array variable

Hi,
I had implemented this:
import java.awt.*;
import javax.swing.*;
public class Oefening1
     public static void main(String args[])
          int array[]= new int[10];
          int getal;
          JTextArea outputArea = new JTextArea();
          Container container = getContentPane();
          container.add(outputArea);
          public void invoerRij(int array[10])
               output +=" ";
               for(int counter = 0; counter <10;counter++){
                    output +="Geef een getal in"+"\n"+array[counter]+"\n";
                    outputArea.setText(output);
I had comilated this code while the compiler gave errors like these:
A:\Oefening1.java:15: illegal start of expression
          public void invoerRij(int array[10])
^
A:\Oefening1.java:24: ';' expected
^
A:\Oefening1.java:12: cannot resolve symbol
symbol : method getContentPane ()
location: class Oefening1
          Container container = getContentPane();
^
3 errors
Tool completed with exit code 1
Now i have read my book and finded out that the declaration of a method always starts with public.
Can anyone halp me solving these probs? Thanks
Crazydj1

The problem is that you didn't close the previous method definition.
Compiler error messages (in any language) often mistakenly report false errors on perfectly valid code immediately following the actual error.
When you post code on these forums, please wrap in in [code][/code] tags.

Array problem - Related Selects

Good Morning,
I'm a newbie when it comes to this so I apologize ahead of time.
I'm trying to build a Year/Make/Model related select search. I found a HTML, PHP, and the JQuery Related Select Plugin that i'm trying to convert to use with CF.
It looks like i can use an array to replace the PHP page that supplies static data:
<?php
$stateID = $_GET['stateID'];
$countyID = $_GET['countyID'];
$townID = $_GET['townID'];
$html = $_GET['html'];
$states = array();
$states['MA'] = "Massachusetts";
$states['VT'] = "Vermont";
$states['SC'] = "South Carolina";
$counties = array();
$counties['MA']['BARN'] = 'Barnstable';
$counties['MA']['PLYM'] = 'Plymouth';
$counties['VT']['CHIT'] = 'Chittenden';
$counties['SC']['ANDE'] = 'Anderson';
if($stateID && !$countyID && !$townID){
          echo json_encode( $counties[$stateID] );
} elseif( $stateID && $countyID && !$townID ) {
          echo json_encode( $towns[$stateID][$countyID] );
} elseif( isset($villages[$stateID][$countyID][$townID]) ) {
          echo json_encode( $villages[$stateID][$countyID][$townID] );
} else {
          echo '{}';
?>
I'm tryiing to convert the following into an array so that i can access it from the index.cfm page:
<cfquery name="qYear" datasource="MyDS" username="MyUser" password="MyPass">
    select distinct YearRange
    from ExactFit2012
    order by YearRange
</cfquery>
<cfquery name="qMake" datasource="MyDS" username="MyUser" password="MyPass">
    select distinct Make
    from ExactFit2012
    order by Make
</cfquery>
<cfquery name="qModel" datasource="MyDS" username="MyUser" password="MyPass">
    select distinct Model
    from ExactFit2012
    order by Model
</cfquery>
<cfset myYear = ListToArray(ValueList(qYear.YearRange)) />
<cfset myMake = ListToArray(ValueList(qMake.Make)) />
<cfset myModel = ListToArray(ValueList(qModel.Model)) />
<Cfoutput>
#myYear#<br>
#myMake#<br>
#myModel#
</Cfoutput>
When i do this i get the error:
Error Occurred While Processing Request

Array Trouble

So I am new to Java, and took my first semester of a java course. It was hard for me at first, but I am slowly improving. My professor posted this as our last assignment for the semester, and I am having trouble with it as it involves arrays. I do not really know where to start, and any help would be greatly appreciated. I will post the assignment below, followed by the small bit of code I have so far. By no means do I want the answers to this, as I actually do enjoy learning, but any type of help, input, suggestions, etc are greatly appreciated. Thanks in advance!
Write a program which prompts the user to input a series of characters, one at a time. The program will stop prompting the user for characters once the user enters an exclamation point ('!').
Using an array, count the number of occurrences of each letter (regardless of whether it is upper or lower case (so for example, an 'A' and an 'a' both count for the first letter of the alphabet). In a separate counter, also count the total number of "other" characters ('.', '?', ' ', '2', etc.). The final exclamation point does not count.
Print out the count for each letter found (but not for those which where not found!)
Print the count of the non-letter characters.
List the characters that were not found (e.g. "The following letters were not found: t, z, c.").
By inspecting the array, print out the total number of all of the vowels, and the total number of all of the consonants.
Finally, print out which letter was found the most times. (Note there may be more than one letter which has the maximum count attached to it.) Also, print out which letter (or letters) was found the least number of times, but make certain to exclude letters which were not found at all.
This is the small amount of code I have thus far.
import javax.swing.JOptionPane;
public class asgn6 {
   public static void main( String[] args )
      int character;
       String letter = JOptionPane.showInputDialog("Please enter a letter (Type ! when finished) ");
       character = Integer.parseInt (letter);
     if(letter.equals("!"))
     System.exit(0);
}

char letter;
do {
String input = JOptionPane.showInputDialog("Please enter a letter (Type ! when finished) ");
letter= input.charAt(0);
}while (letter != '!');So I figured out the loop!Exellent, that's exactly right.
Now I need a lot of assistance for the arrays part, as that is what I understand least with this assignment.The easiest way I see it is to make an array of ints 128 elements long. Each element is the counter for the character that indexes it.
For instance, 'A' is ASCII 65. So array[65] is the counter for how many times 'A' has been seen. You can use chars like you would use ints, so you can do this: array['A'] and it will convert it to it's ASCII value. Each time you read an input char, increment array[letter].
Then when you're done with input, you can print out each one like this
for each element i in the array
   print out (char)i followed by array

Modify hard coded array to database pull

Hello all,
I'm new to the array stuff, and am having problems finding a tutorial or instructions on how to modify a hard coded array to something pulled from a database. I can only find tutorials on how to do it hardcoded. They keep saying it is possible, but never say how to do it. The original tutorial that I'm trying to learn which brought up this question can be found at: http://www.brandspankingnew.net/archive/2007/02/ajax_auto_suggest_v2.html
So as an example, if I've got the database connection already established as:
   $con = mysql_connect("localhost", "root", "") or die('Could not connect to server');
   mysql_select_db("my_database", $con) or die('Could not connect to database');
With fields as my_database_names, my_database_ratings, and my_database_images; how do I modify the below code to use the database information instead of using the hardcoded array? Any suggestions (or letting me know of where a good tutorial is) would be appreciated.
<?php
note:
this is just a static test version using a hard-coded countries array.
normally you would be populating the array out of a database
the returned xml has the following structure
<results>
<rs>foo</rs>
<rs>bar</rs>
</results>

Thank you so much. I was planning on hand coding it because my objective is to learn, not to have dreamweaver do it for me, so I will check out the link :
http://docs.php.net/manual/en/mysqli.query.php.
LOL, I thought I was just starting to understand MySQL, and now I've got to start learning MySQLi. I hope there is not too much different between the two. Thanks again.

Trying to 'simulate' an array of strings

In pseudo-code what I would like to do is this:
Array[x][3]
Array[1][1] = "First"
Array[1][2] = "Data1"
Array[1][3] = true
Array[2][1] = "Second"
Array[2][2] = "Data2"
Array[2][3] = false
counter = 1
while(counter < 3) {
print Array[counter][1]
counter++
In Java-think I created a class of data, and wanted to create a series of elements (array) of this class. But, suprise, my code snippit below doesn't work....
class DataSaved {
String InputName;
String InputValue;
boolean IsHidden;
public class test {
public static void main(String [] args) {
DataSaved dataum;
int counter = 0;
dataum = (DataSaved) DataSaved.firstElement();
dataum.addElement("first","1data",true);
dataum.addElement("second","2data",true);
dataum.addElement("third","3data",true);
dataum.addElement("xxxfirst","4data",true);
dataum.addElement("fxxirst","5data",true);
dataum.addElement("sixfirst","6data",true);
dataum.addElement("7first","7data",true);
dataum.addElement("8first","8data",true);
dataum.addElement("9first","9data",true);
// move to the top element
datum.firstElement();
while (counter < 6 ){
System.out.println(dataum.nextElement());
counter++;
So....what am I not understanding, and how can I make this snippit work?

Great, now your DataSaved class is correct.
The next step is how to deal with arrays.
Suppose you have an array of Strings. Here's how it looks like:
String[] myArray;Before you can use it, you have to actually occupy the space it needs. (Arrays are objects in Java, so basically, but sloppily speaking, you have to instantiate an "array class"):
myArray = new String[15];The length of the arrays in Java is constant. You have to tell the length during construction time, and you won't be able to change it later.
Also, if you create an array as above, each of the elements will contain null (were it an array of primitive types, it would contain the appropriate version of zero for that primitive type). Therefore, you have to load the elements one by one:
myArray[0] = new String("first string");
myArray[1] = new String("second string");
myArray[14] = new String("last string");As you see, indexing starts with zero. I also have to note, that "new String(...)" is an unnecessary and in most cases poor programming technic, the string constants would do in this case (but not if the array is not an array of strings but array of some kind of objects).
Another note. It's usually a bad programming technic to reach the fields of another class. Sometimes we do, but only when we have good reason. It's better if you provide setXXX and getXXX methods, and let your fields to have private access:
class DataSaved {
   // your current code appears here
   public void setInputName(String name) {
      InputName = name;
   public String getInputName() {
      return InputName;
}Now, your cycle which retrieves the values should look something like this:
for (int cntr=0; cntr<myArray.length; cntr++) {
   System.out.println(myArray[cntr].getInputName());
}That myArray.length is an attribute of the arrays, which tells you the length of the array. Now, if you have to change the length later, you don't have to scrutinize your code, since the "magic number" appears in the code exactly once.
You may read about the arrays and how they're handled in Java here:
http://java.sun.com/docs/books/tutorial/java/data/arrays.html
That ArrayList is another story; if you have succeeded with your array, come back and ask. "Preview": ArrayList is a way how to deal with arrays which might be expanded and shrunk as needed.
You also might consider reading the tutorial about the collections (perhaps in a later time):
http://java.sun.com/docs/books/tutorial/collections/index.html

Arrays,bubblesort, and binary search

Hi I need help I have been working on this homework assignment for the past week and I can't seem to get it so if anyone can help me to figure out what is wrong I would reall grateful. Thanks ahead of time for the help.
Here is what is required for the assignment and also the errors I am getting.
Thanks!
Write a program that sorts an integer array in ascending order and checks whether an integer entered by user is in the array or not. Please follow the following steps to complete the assignment:
1. Declare and create a one-dimensional array consisting of 20 integers.
2. Read 20 integers from the user to initialize the array. Use input dialog box and repetition statement.
3. Build an output string containing the content of the array.
4. Sort the array in ascending order using bubbleSort( ) and swap( ) methods. Then, append the content of the sorted array to the output string.
5. Read an integer search key from the user;
6. Use binarySearch( ) method to check whether the search key is in the array or not. Then, append the search result to the output string.
7. Display the output string in a message box.
Here is my code
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class SortSearch {
public static void main (String args[])
String input, ouput;
int key;
int index;
int[] array=new int [20];
input=JOptionPane.showInputDialog("Enter 20 Numbers");
for(int counter=0; counter<array.length; counter++)
output+=counter+"\t"+array[counter]+"\n";
array(counter)=Integer.parseInt(input);
JTextArea inputArea=new JTextArea();
outputArea.setText(output);
public void bubblesort(int array2[] )
for(int pass=1; pass<array2.length; pass++){
for(int element=0; element<array2.length-1; element++){

return middle;
else if(key<array[middle] )
