Function help with strings
I have a list of at least 5000 names in my system and i want to make a search module based on the list of those names.
NAME
Ashish Nanda

jim Chang
I want to to create an id column from this list i have and then add it in the table where i will put in names as
Id
ASHISHNANDA
MICHEALDOUGLAS
JOHN
STEVENSEAGAL
JIMCHANG
i KNOW I CAN USE THE UPPER TO CONVERT THE STRINGS IN TO UPPERCASE FORMAT BUT HOW DO I GET RID OF THE SPACES IN BETWEEN WHICH OCCUR AT RANDOM INTERVALS.
Any Suggestions?
Best Regards,

Hey guys,
I need some help with String Parsing. i hope experts here will help me.
i'm reading a text file and getting data as String in this format
*ABR, PAT MSSA 2009 7001 B ABC Y
*VBR, SAT ZSSA 2008 5001 A CED N
*ABC, AAT CSSA 5008 001 A AZX N
*CBC, CAT FSSA 308 5001 A XCV N
Now from following lines i have to extract Number data i.e. 2009 and 7001 from 1st line. 2008 and 5001 from 2nd line and so on.
Can anyone pls suggest me any way to get the data that i want from these Strings
Thanks for your time to read this.
Regards,
samThanks for the reply
Data length can vary. ABR, PAT is the last name, First Name of the Users.
it can be following or any other combination. i just need 2 set of numbers from the complete line rest i can ignore. Any other way to get that
*ABRaaassd, PATfffff MSSA 2009 7001 B ABC Y
*VBRaa, SATaa ZSSA 2008 5001 A CED N

Hello,
First off thanks in advance to anyone who helps. I am trying to write a program that using a class string object to convert this kind of "text speech" to english. For example if the user inputs "HowAreYou?", I want the program to output "How are you?" I am having too much trouble with strings for some reason. This is what I have so far and I am not sure where to go from here. Should I use a do loop to check through the input string until it is done seperating the words? And how should I go about doing that?
import java.util.Scanner;
public class P8
public static void main( String args[] )
char choice;
String line = null;
String answer = null;
Scanner scan = new Scanner(System.in);
do
System.out.println();
System.out.print("ENTER TextSpeak sentence(s): ");
line = scan.nextLine();
System.out.print( "Converted to English: \t ");
System.out.print( textSpeaktoEng( line ) );
System.out.println();
System.out.print("Want more TextSpeak?\t\t ");
answer = scan.next();
choice = answer.charAt(0);
if( scan.hasNextLine() )
answer = scan.nextLine();
}while(choice != 'N' && choice != 'n');
public static String textSpeakToEng(String s)
String engStr = null;
if( Character.isUpperCase( s.charAt(j) ) )
engStr += ? ?;
engStr += Character.toLowerCase( s.charAt(j) );
scan.close();
}I got my program to compile and run but I have a problem. If I input something like "ThisForumIsGreat" it will output just "t f i g" in lower case letters. Any suggestions?
import java.util.Scanner;
public class P8
public static void main( String args[] )
char choice; // Repeat until n or N
String line = null; // Sentences to toTextSpeak
String answer = null; // Repeat program scan
Scanner scan = new Scanner(System.in); // Read from keyboard
do
System.out.println();
System.out.print("ENTER TextSpeak sentence(s): ");
line = scan.nextLine(); // Read input line
System.out.print( "Converted to English: \t ");
System.out.print( textSpeakToEng( line ) );
System.out.println();
System.out.print("Want more TextSpeak?\t\t ");
answer = scan.next(); // Read line, assign to string
choice = answer.charAt(0); // Assign 1st character
if( scan.hasNextLine() ) // <ENTER> character
answer = scan.nextLine(); // Read line, discard
}while(choice != 'N' && choice != 'n'); // Repeat until input start n or N
public static String textSpeakToEng(String s)
String engStr = null;
int i;
for ( i = 0; i < s.length(); ++i )
if( Character.isUpperCase( s.charAt(i) ) )
engStr += " "; // Append 1 blank space
engStr += Character.toLowerCase( s.charAt(i) ); // Append lowercase
return( engStr );

Max function coupled with string concat....please help...
Dear All,
I do have to solve one query which requirement is below :
Basic data in table looks like this:
SEQ NO PCode Last_updated_date
1 AA 1-Feb-2008
1 Ab 2-Jan-2009
1 Ac 3-Jan-2009
2 AA 5-Jan-2009
2 AD 31-Dec-2008
2 AF 31-Oct-2008
3 AK 1-Jan-2009
3 GH 2-Jan-2009
3 AA 3-Jan-2009
Now i need the output like :
I need max of timestamp under each seqence no (i mean groupby) (i am really easy to find this) but it should show all pcode concated while displaying the result..
okay.. the below is required out put..:
for example in for seq 1 number one..max of timestamp is 1-Feb-2008 with pcode AA..so it should display like
seqno Pcode max(timestamp)
1 AAABAC 1-Feb-2008
(logic is it should select max(timestamp) record and concat all all other pcode(only) to existing pcode eventough their timestamp is not max)
like this for all other sequence groups...
Please help..is this possible in a sqlquery to include this logic...
Thanks for help

Need help with string field formula
Post Author: dshallah
CA Forum: Formula
What I am trying to accomplish:
The report has item numbers and each item number has the
potential to be associated with up to three u2018binsu2019. So the fields are u2018item
numberu2019, u2018bin1, u2018bin2u2019 and u2018bin3u2019.
I tried to write a u2018if thenu2019 statement that would only show
records that had a value of less than 1 in each u2018binu2019 field. When I try to
write the statement I get a message that says u2018A string is required hereu2019 and
it highlights the number 1 in my statement. I have a feeling itu2019s because the u2018binu2019
fields are string fields and not number fieldsu2026? So I am not sure the proper
procedure to correct this. Thus help is needed and appreciated.
Here is what I wrote:
if {IC_LOC_HIST.BIN_NAME_1} < 1 then
{IC_LOC_HIST.BIN_NAME_1}
What is correct way to write a statement that will show me
the zero values in each column of bin fields?
Thanks!Post Author: bettername
CA Forum: Formula
You must have a non-numeric value in there somewhere - up in the top left of the formula editor window, it'll show you the variables you've passed to the formula, which should help track down what's going on.
You could try and check that the value is a number first by using something like:
if isnull({IC_LOC_HIST.BIN_NAME_1}) = false and isnumeric({IC_LOC_HIST.BIN_NAME_1}) = false and then "Error - Should be a Number!"
else
if isnumeric({IC_LOC_HIST.BIN_NAME_1}) = true and tonumber({IC_LOC_HIST.BIN_NAME_1})<1 then {IC_LOC_HIST.BIN_NAME_1}) -
Can anyone help with string manipulation please?
I am trying to change this string 43180-1-0001-37 into the following expression 43181-0001-37
It is a string for Project No + Job Phase + Drawing No + Item No.
The reduction of '43180' to '4318' is causing me the problem, I have the concatenation.
Current report code is
SELECT Os.[Orderno-o] As 'Order Number'
,Ph.PH_PHASE_NO + '.' + Re.REQUISITION_NUMBER As 'Req. Number'
,Pl.ID As 'Item ID'
,@CurrentProjectNumber + '-' + Ph.PH_PHASE_NO + '-' + Dr.DRAWING_NO + '-' + Cast(Pl.ITEM_NO As varchar(max)) As 'Drg & Item No.'
It is this line giving me the problem?
,@CurrentProjectNumber + '-' + Ph.PH_PHASE_NO + '-' + Dr.DRAWING_NO + '-' + Cast(Pl.ITEM_NO As varchar(max)) As 'Drg & Item No.'Hi uh... Mr. Rubbish at SQL :)
Unfortunately, there are many elements in your questions which aren't clear:
1. What is the content in your columns PH_PHASE_NO, DRAWING_NO, ITEM_NO and what is their data type?
2. What is the content of the variable @CurrentProjectNumber and what is its data type?
3. It's unclear what is the logic behind the "reduction" of '43180' to '4318'. Do you want to remove trailing zeros? Shorten the value by one character? Because from what I see in your first sentence, it seems like you simply want to add 1 to '43180'
and turn it into '43181'. That's a simple +1 operation. I also notice that you want to remove the "Job Phase" part from the string (which is "1" in your case)? Or do you need to add its value to the "Project No" (43180)? It's
all quite confusing.
Clarification would be highly appreciated.
I would suggest, if you can, to please explain what you need NOT by specific examples, but by explaining your requirements IN GENERAL. In other words, don't use specific values like '43180', but start with a variable like 'X', and then let us know specifically
what operation you want to perform on it (e.g. 'add 1' / 'remove trailing zeros' / 'shorten by one character' / 'add to it the value of some column' etc.). This will make it easier to understand the algorithm needed.

Need a little help with strings
So I would like to have the user input a month by using the abbreviation ex. (mar or apr) instead. So I want month to be a string right? When I tried that I get an error. What should this look like?
import java.util.*;
public class MonthSwitch
static Scanner console = new Scanner(System.in);
public static void main(String[] args)
int month;
System.out.print("Enter a Month: ex. Jan, Feb, Mar ect...");
month = console.nextInt();
System.out.println();
switch (month)
case 1: System.out.println("First Quarter");
case 2: System.out.println("First Quarter");
case 3: System.out.println("First Quarter");
break;
case 4: System.out.println("Second Quarter");
case 5: System.out.println("Second Quarter");
case 6: System.out.println("Second Quarter");
break;
case 7: System.out.println("Third Quarter");
case 8: System.out.println("Third Quarter");
case 9: System.out.println("Third Quarter");
break;
case 10: System.out.println("Fouth Quarter");
case 11: System.out.println("Fouth Quarter");
case 12: System.out.println("Fouth Quarter");
break;
default: System.out.println("Sorry Input is Invalid");
}Edited by: NewJavaKid on Apr 29, 2009 10:47 PMIf you use an enum construct, then you can create a switch that operates on the abbreviated month value. Note that I made a correction in the Scanner input code, and converted the input to lowercase (to assure a match with the enum) in case capitals were used. The switch was revised to work correctly with enums, which requires the try/catch to catch illegal input.
import java.util.Scanner;
public class Xy
static Scanner console = new Scanner(System.in);
enum Month
jan, feb, mar, apr, may, jun, jul, aug, sep, oct, nov, dec
public static void main(String[] args)
System.out.print("Enter a Month: ex. Jan, Feb, Mar etc...");
String shortMonth = console.next().toLowerCase();
System.out.println();
try
switch (Month.valueOf(shortMonth))
case jan:
case feb:
case mar:
System.out.println("First Quarter");
break;
case apr:
case may:
case jun:
System.out.println("Second Quarter");
break;
case jul:
case aug:
case sep:
System.out.println("Third Quarter");
break;
case oct:
case nov:
case dec:
System.out.println("Fouth Quarter");
catch (IllegalArgumentException iae)
System.out.println("Sorry, input is invalid");

Help with String/ and or Array loading and comparing
Hi all,
I'm having some problems with trying to find the best way to achieve the following on a Poker Dealing program. I randomly shuffle a 52 card deck of playing cards and deal out 5 cards. Cool...
Now I have to go back thru the String and determine if my hand of cards contains
a pair
2 pair
3 of a kind
Full House
etc etc
I am trying to do String comparisons (there is an empty compareCards method in my code right now, but I'm getting a bit frustrated as to find the best way to do it... Would an array load in a separate method be a better way???? What I need to do is after I load my hand , is to display a message stating a pair, 3 of a kind , etc etc.....
Thanks in advance
Mike

Each player gets an array of five cards. You could the loop through each hand and increment values held in another array by one according to the value of the card. Haven't coded the following up but it should work I think.
// hand [ ] represents the cards held by that player
int handChecker [ ] = new int [14]
for (int counter = 0; counter < 5; ++ counter)
// 1st card is an Ace. handChecker [1] will be incrementd by one and so on
// 2nd card is a 9. handChecker[9] will be incremented by one.
handChecker[hand[counter]] += 1;
// Loop through the array handChecker to find pairs etc.
boolean pair = false;
bollean tofk = false;
for (int counter = 1; counter < 14; ++ counter)
if (handChecker[counter] == 2)
pair = true;
if (handChecker[counter] == 3)

ReadSequentialFile.java:181: getStartDate(Date) in Employee cannot be applied to
String.valueOf( record.getStartDate() ),
^In the employee class I did getStartDate like:
public Date getStartDate(Date sDate)
return start;
}Can anybody tell me why i get this error and how to solve it?so in
the employee class i need to chnage the getDate
method?Well, it's your class, so it's up to you to know what that method is supposed to do, to give it a signature that allows it to be called with the data to do its job, and the pass it the right data when you call it.
Don't think only about how to make the compiler happy. Think about what you're trying to accomplish and in what way the current code doesn't do that. The compiler can only really detect syntactical errors, but sometimes those errors arise as the result of logic errors in your mental picture of the steps to follow. So take the compiler's complaints as a hint to reexamine what you're doing and see if it makes sense. -
I have declared a String array as
String[] records;
Later in the code I wrote
records[records.length] = qualifiedRecDefName.substring(lastIndex+1, qualifiedRecDefName.length());
I am getting a NullPointerException. I see that records is null. How can I correct this. Thanks.You have to create your array using new.String[] records = new String[10];Also, arrays go from 0 to length-1, so if you want to access the last item, it's records[records.length-1]as long as records.length > 0.

Function help with corresponding boxes
I have an assignment where I have to add a number to the corresponding box to its left, but it seems really piecemeal to do it one by one. Is there a faster way? (I have to calculate Absolute Deviation)
Ashley,
the "boxes" are called cells. you can fill cells with a formula by selecting a cell with the formula in it already, the copy the cell.
no select ALL the cells you want to fill and paste . If you happen to want to fill the cells in a column with the same formula, enter the formula in the first row of the column, then select the cell, then copy. Now click the column header (the letter at the top) to highlight every cell of that column, paste. -

Need help with trim and null function
Hi all,
I need help with a query. I use the trim function to get the first three characters of a string. How do I write my query so if a null value occurs in combination with my trim to say 'Null' in my results?
ThanksHi,
Thanks for the reply. What am I doing wrong?
SELECT trim(SUBSTR(AL1.user_data_text,1,3)),NVL
(AL1.user_data_text,'XX')
FROM Table
I want the XX to appear in the same column as the
trim.The main thing you're doing wrong is not formatting your code. The solution may become obvious if you do.
What you're saying is:
SELECT trim ( SUBSTR (AL1.user_data_text, 1, 3))
, NVL ( AL1.user_data_text, 'XX' )
FROM Tablewhich makes it clear that you're SELECTing two columns, when you only want to have one.
If you want that column to be exactly like the first column you're currently SELECTing, except that when that column is NULL you want it to be 'XX', then you have to apply NVL to that column, like this:
SELECT NVL ( trim ( SUBSTR (AL1.user_data_text, 1, 3))
, 'XX'
FROM Table
