Help me to understand this simple program..

Below coding cannot be compiled...please help me
public class demo{
private String employeeName;
public static void main(String args[]) {
System.out.println("Hello, World");
employeeName = "Jeremy";
showMessage("Employee:");
static void showMessage(String msg) {
int i;
System.out.println(msg+ " " +employeeName);
}

When posting code, make sure you use the CODE tags to preserve highlighting. Otherwise nobody will read it.
Also, if you have errors, tell us what they are! Copy the whole error message here, and point out which line numbers are mentioned in the error.
At first glance though, you should learn exactly what "static" means in a Java program.

Pls help to understand this routine program

Pls help to understand this routine program written in transformation level for a field.
Data a Type /bic/oizsnote_2.
Data: l_len type i,
      l_time type i.
Move source_fields-zztdline+60(60) TO a.
l_len = STRLEN(a).
DO l_len TIMES.
IF a+l_time(1) CN
',<>?/:;"''ABCDEFGHIJKLMNOPQTRSTUVWXYZ abcdefghijklmnopqrstuvwxyz!%^&' & '*' & "()__+=12346567890'
a+l_time(1) = '~'.
Endif.
l_time = l_time + 1.
enddo.
replace all occurrences of '~' in a with space.
Result = a.
not having much exposure in ABAP programming.

In addition to the above to posts..
HI Raj,
Your routine is used to remove the invalid characters.
IF A+l_time(1) CN
A is a Char which contains the data .*
I_time is used for iteration(itu2019ll check each char by char in a word/Sentence).
*CN u2013 Contains not
,?/:;"''ABCDEFGHIJKLMNOPQTRSTUVWXYZ abcdefghijklmnopqrstuvwxyz!%^&' & '*' & "()__+=12346567890.
These are the Valid chars and numbers which will be accepted by BW system, System will throw an error only when load receives a char which is not there in the above. And that char will be treated as a Invalid Char.
A+l_time(1) = '~'.
What ever the special/Invalid char appears in the load apart from the above mentioned, system will convert them to u2018~u2019
REPLACE ALL OCCURRENCES OF '~' IN a WITH space.
   CONDENSE A.
System will replace all the ~ with space, then condenses the space.
You can do this using RSKC transaction instead of going for routine.

Left outer join VS Is NULL .. Please help me to understand this.

Hi Experts,
I have a requirement to use Leftouter join on a column. But unfortunately i couldnt implement this in OBIEE. so instead iam using = and is NULL condition. kindly help me to understand this or give me a solution.
Advance Thanks

Can anybody help me to understand this RMI registry service code?

RMI is so difficult to me. please let me know following code what it means.
If this class is instantiated with 50000 port number,
Does RMI Registry Service get started with 50000 port number in place of rmiregistry commands?
And I don't have to execute rmiregistry command?
thanks in advance.

You don't have any need to understand this code. The complication is due to the registry needing a fixed objectID.
You just need to know the methods of java.rmi.registry.LocateRegistry class. This allows you to start an RMI Registry inside your JVM and give it any TCP port number you like.

I don't understand why this simple program will not print. Help please!!!

This program runs with no errors, it just doesn't print anything. Anyone have a clue as to why it doesn't print anything?
Here is my code:
import javax.swing.JOptionPane;
public class Converter {
public static void main(String[] args) {
int a,b,c;
int inputNum=Integer.parseInt(JOptionPane.showInputDialog(null," Enter a length in yards: "));
String measurement = JOptionPane.showInputDialog(null,"Enter the unit of conversion (inches, feet, or centiyards): ");
if (measurement == "inches"){
a = inputNum*36;
System.out.println(a + "inches");
else if (measurement == "feet"){
b = inputNum*3;
System.out.println(b + "feet");
else if (measurement == "centiyards"){
c = inputNum*100;
System.out.println(c + "centiyards");
}

Don't confuse String's equals() method with the equality operator '=='. The == operator checks that two references refer to the same object. If you want to compare the contents of Strings (whether two strings contain the same character sequence), use equals(), e.g. if (str1.equals(str2))...
Example:String s1 = "foo";
String s2 = new String("foo");
System.out.println("s1 == s2: " + (s1 == s2)); // false
System.out.println("s1.equals(s2): " + (s1.equals(s2))); // trueFor more information, check out the Java FAQ

Pls find out the exception in this simple program...

Pls tell me wots the reason of the exception in this program since im getting an exception like this..

Can't understand this thread program.

Hi ..this is a part of program from http://java.sun.com/docs/books/tutorial/essential/concurrency/simple.html ..I dnt understand the last block in the following program,the one starting from "if (args.length > 0) { ......."
can somebody tell why is it used?
public static void main(String args[]) throws InterruptedException {
        //Delay, in milliseconds before we interrupt MessageLoop
        //thread (default one hour).
        long patience = 1000 * 60 * 60;
        //If command line argument present, gives patience in seconds.
        if (args.length > 0) {
            try {
                patience = Long.parseLong(args[0]) * 1000;
            } catch (NumberFormatException e) {
                System.err.println("Argument must be an integer.");
                System.exit(1);
        }

Well it says in the code comments:
//Delay, in milliseconds before we interrupt MessageLoop
        //thread (default one hour).So I am guessing that that is the delay period, but the snippet of code you pasted actually does nothing except set a value patience and then look for a command line argument and if it exists attempts to set patience to that value.

When we compile with rmic skeleton and stub get created then we hav to place stub at each client ???Your remote client applcation need only _Stub.class fiels.
Is there way by which we can know how many clients are connected to the
server and there IP address, can anyone give the code... I guess that you should use a RMI login/logout method to register/unregister your client connection information into a databse or a simple static Hashtable(Vector) object.

Help needed in understanding this question, please.

Here is the question:
What is the number displayed when the following program is compiled and run.
class test {
    public static void main(String args[]) {
        test test1 = new test();
            System.out.println(test1.xyz(100));
    public int xyz(int num) {
        if(num == 1) return 1;
        else return(xyz(num-1) + num);
Answer= 5050.
I'll be honest I am lost as to what happens in this code. Any help in explaining what happens in the code would be gratefully received, thanks, Dave.

public int xyz(int num) {
if(num == 1) return 1;
else return(xyz(num-1) + num);
it's called recursion, the method calls itself
xyz(100) returns
xyz(99)+100 which returns
xyz(98)+99 which returns
xyz(97)+98 which returns
xyz(99)+100 which returns
until you get to xyz(1) which returns 1
so starting from the end of the recursion you get
(for num = 2): 1+2
(for num = 3): 3+3
(for num = 4): 6+4
(for num = 5): 10+5
(for num = 100): 4950+100

Plz tell me the error at this simple program

at this orogram i want the user to input the number and then he get th factorial...
my program is:
import javax.swing.JOptionPane;
public class Ch4_32a
public static void main (String[]args)
int f=1, i=1,N;
String E;
          String M = JOptionPane.showInputDialog("Enter the number");
          N=Integer.parseInt(M);
          while(i<=N);
               f=f*i;
               i++;
          JOptionPane.showMessageDialog(null,"the factorial is"+E);
          f=Integer.parseInt(E);
******and when i copile it the result is:
C:\Documents and Settings\F A M I L Y\Desktop\MyProgs\azza\Ch4_32a.java:22: variable E might not have been initialized
          JOptionPane.showMessageDialog(null,"the factorial is"+E);
^
1 error
it tell me to init the value of E but ir is a string,,
so plz help me to get the real error

i delete the (parseInt{) and compile it completle
but when i excut it the firs widow appear (Ent the number)
i Enter the number and then "ok" but the second window don't appear which well tell me the result({f)

I am not able to understand this java program

What is the output of bellow code ?
public class Bean{
    private String str;
    Bean(String str ){
        this.str = str;
    public String getStr() {
        return str;
    public boolean equals(Object o){
        if (!(o instanceof Bean)) {
            return false;
        return ((Bean) o).getStr().equals(str);
    public int hashCode() {
        return 12345;
    public String toString() {
        return str;
import java.util.HashSet;
public class Test {
    public static void main(String ... sss) {
        HashSet myMap = new HashSet();
        String s1 = new String("das");
        String s2 = new String("das");
        Bean s3 = new Bean("abcdef");
        Bean s4 = new Bean("abcdef");
        myMap.add(s1);
        myMap.add(s2);
        myMap.add(s3);
        myMap.add(s4);
        System.out.println(myMap);
}(Choose correct one from multiple bellow)
1) das abcdef
2) das abcdef das abcdef
3) das das abcdef abcdef
4) das
What i understand is that the following constructor
Bean(String str ){
        this.str = str;
    }is used to initialize the instance variable
private String str;then we have overridden the equals method, in this method we first check if o is not an instance of Bean class whereby we return false
then we are calling getStr() and equals(str)
return ((Bean) o).getStr().equals(str);the getStr() method is going to return the instance variable we initialized. SO we will be having something like
str.equals(str) Here I am not clear what is going to be the output. Please explain in detail

1. [das, abcdef]
map create a pair key - value, similar to Dictionary.
"Hash map structures consist of an internal array where elements are stored. Since the internal storage is an array, clearly there must be a mechanism for determining an index into the array for an arbitrary key. In fact, the mechanism needs to give an integer index value which is smaller than the size of the array. This mechanism is called the hash function. In Java hashed based Maps, the hash function converts any object into an integer that fits into the internal array. You don't have to look hard to find an easily available hash function: every object has a hashCode() method which returns an integer value. To map that value into any array, it is sufficient to convert it to a positive value and take the remainder after dividing by the array size. "
you will get the same hashcode for the same value!

Help needed to understand this problem

Hello Guys,
can some one take a look and let me know that the following code segment should do what it seems to be doing?
StyledDocument doc=(StyledDocument)editor.getDocument();
MutableAttributeSet attr=new SimpleAttributeSet();
StyleConstants.setFontFamily(attr,fontFamily);
switch (fontStyle){
case 1:
StyleConstants.setBold(attr,false);
break;
case 2:
StyleConstants.setItalic(attr,false);
break;
StyleConstants.setFontSize(attr,fontSize);
doc.setCharacterAttributes(0,doc.getLength(),attr,true);
editor.setDocument(doc);
I am trying to change font properties at the runtime in a JTextPane.which has a file loaded into it.Once I click a button the above changes should apply,,but they don't
Thanks

Nevermind..I figured it out...:-)

Help needed in understanding the concept of hierarchical queries

I really need help in this matter. I have a flafile containing about 4000 rows. It is from my supplier, it's structure is as follows:
create table Flatfile
(Pgroup varchar2(30),
Pclass varchar2(30),
Manufacturer varchar2(30),
Article varchar2(30),
Price Number(6,2));
Insert into Flatfile Values
('Application Software','Database Software','Oracle','Oracle 10G',115);
Insert into Flatfile Values
('Application Software','Database Software','Microsoft','MS SQL Server 2000',200);
Insert into Flatfile Values
('Application Software','Spreadsheet Software','Microsoft','Excel',100);
Insert into Flatfile Values
('Monitor','15"','Acer','Acer 15"" TFT superscreen',199);
Insert into Flatfile Values
('Monitor','15"','Sony','Sony R1500 flat',225);
Insert into Flatfile Values
('Monitor','17"','Philips','Philips Flatscreen',250);
Insert into Flatfile Values
('Monitor','19"','Viewsonic','Viewsonic PLasma Monitor',275);
Insert into Flatfile Values
('Processor','AMD','AMD','FX-55',600);
Insert into Flatfile Values
('Processor','Intel','Intel','P4 3 GHZ',399);
My goal is to make a hierarchical query with the start with and connect by clauses. From what I have read is that I need to normalize the data of the flatfile.
How do I achieve a table which I can query so that the query will represent the hierarchy that exists. Namely
Pgroup
++Pclasse
Application Software
++Database Software
++Spreadsheet Software
So a 2-level hierarchy. I'd like to understand this simple concept first. I built on the knowledge that I gain. So the questions are:
1.What do I need to do to make the table so that I can use a hierarchical query on it?
2. How should the query syntax be?
3. Is it also possible to get the data in the hierarchical query sorted asec?
I would only like to use the simple structures of the start with and connect by clauses first. I've read there are some new additions to 10G. The problem with the examples used by the tutorials is that the tables are already made so that they are suitable for hierarchical queries. I hope to understand it by this example. And take it a step further.
Sincerely,
Pete

Primarily hierarchy query serves to process tree-like structures which RDBMS simulates using through parent-child relation, often in a single table (see famoust
EMP table where employee can have the manager who is an employee at the same time).
In your case it could look like:

As for the ordering question you can use siblings ordering:

3 connect by prior pclass = pgroup
4 order siblings by 1 desc

Please help me with simple program

Can someone please write a simple program for me that opens up a webpage in the center of the screen , with a set size, and then asks the user where they would like to click on the screen. Then once the person clicks it asks how many times they would like to click there, and then once they enter the # the program opens up the webpage (in the center at the same spot as before, with the same set size) and automatically clicks on the predesignated spot , and then closes all open internet windows, and keeps doing it for however many times the person chose. PLEASE HELP ME WITH THIS!!! If you could, please post the source code here. Thank you so much to whoever helps me!!!!!!!

If it's not to learn, then what is the purpose of
this project?well, if it's not HW and its not for learning java, then why the hell would anyone like to have a program that may open a webpage and then repeatedly click on predefined place...
let me see...
now if he had asked for program that fakes IP as well, then i would suggest that he tryes to generate unique clicks, but now... i'm not sure... maybe just voting in some polls or smthing... though, i would not create a program that clicks on the link or form element, but rather just reload url with given parameters for N times...

Help me to understand this simple program..
