Help With String parsing

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,
sam

Thanks 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

thanks,

maybe its a FileReader deal.. Im not sure, maybe try using InputStreams. This code works for me (it reads from data.txt), give it a try and see if it works:
import java.io.*;
public class Example {
     public Example() throws IOException {
          BufferedReader b = new BufferedReader(new InputStreamReader(new FileInputStream("data.txt")));
          String s = "";
          while ((s = b.readLine()) != null) {
               System.out.println(s);
          b.close();
     public static void main(String[] args) {
          try {
               new Example();
          catch (IOException e) {
               e.printStackTrace();
}

Help with string object code

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 );

Need help with input, parsing, and loop in one program

I am doing an assignment that is supposed to:
# ask the user for a URL
# For the entered URL, read all the HTML text from the page and extract all links (other URLs) and image names. These should be printed to the console window.
# Reprompt for a URL until the user presses the cancel button.
# Define at least one helper method that serves a practical purpose that your main method will use. Note that your method(s) should serve a useful purpose, and it should make sense that they are separated out from the main method.
So far, I figured out how to ask if the user would like to play again, though I can't make it loop to play again. The "NO_OPTION" works fine and exits out.
I cannot figure out at all how to ask for the URL and then use that URL to try to parse the HTML to find the links and pictures.
for the loop, is it:
do{
...//all the stuff//
}while (option == JOptionPane.YES_OPTION) ?(I think I have to parse, looking for "img src" and "a href", anyway)
The biggest thing I'm getting hung up about is where to start. All it'll do is ask for the URL, say there is an error, and ask if I want to do it again. Don't know how to make it loop again. Like I said, I think it's a do while loop but am not completely sure where it goes and how to have it work on the entire thing with message dialoge boxes
To ask for the input, I was trying to make the dialoge box a string so the string would be displayed and have the links extracted
String linkString=
          JOptionPane.showInputDialog("Please enter a URL:");...but it obviously doesn't work like that...
Here is the whole mess so far...I don't know what my question is because I know what I want, just not the terms to ask. help?

import java.io.InputStream;

      System.out.println(inputLine);
      inputLine = reader.readLine();
    catch(Exception e)
      JOptionPane.showMessageDialog(null, "Error reading from file");
    } int answer = JOptionPane.showConfirmDialog(null, "Examine Another URL?", "Click Yes or NO:", JOptionPane.YES_NO_OPTION);

Newbie Help With File Parser

I have an assignment that involves using Java to parse the info on one text file and output to another text file with a header row and a data row both of which need to be tab delimited. I'm relatively new to Java and I'm having a hard time even starting this thing. Any help would be greatly appreciated. The file I have to read from is similar to this:
Report: Fake Report for Fake Loans
Report ID: 000001
Run Date: 04/25/2007
Office Number ID Number DelqMessage
033 000101000 N
034 001234875 Y
035 123456789 N
I would essentially need to get all the field names into the header row and the data in the row below it.
Thanks in advance.

I have been working on this and I almost have it working correctly. I was able to selectively pull the info I need from the original file and I can output to the new file in a vertical form. The last step is to output a header that says RunDate Office Loan DelqMessage with a tab delimiter. I than have to compile the data and output in rows under the header also in tab delimited format. I think I'm right there but I still get one error I cannot resolve of:
Error: java.lang.StringIndexOutOfBoundsException: String index out of range: 4
It is very vague and I have tried everything I can think of to locate the issue so it can be debugged. Below is a copy of the file I'm trying to parse followed by what I have for code so far. Any help would be greatly appreciated.
Sample of report:
Report: Fake Report for Fake Loans
Report ID: 000001
Run Date: 04/25/2007
ASC Number Loan ID DelqMessage
033 000101000 N
034 001234875 Y
035 123456789 N
ASC Number Loan ID DelqMessage
036 741258963 N
037 872563987 N
038 987521455 Y
======================================================================

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!

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})

Node node1 = nodeList.item(i);
Node node2 = org.apache.xpath.XPathAPI.selectSingleNode(node, "//*[name() = 'header']");
Node node3 = org.apache.xpath.XPathAPI.selectSingleNode(node2, "//*[name() = 'id]");
String id = node3.getFirstChild().getNodeValue();
even due i run in a loop and i see node1 containing the right record the other parsing gives me the always the data of the first record.
can't i parse and then re-parse on the node i got?
if the second parsing always done from the root, even due i gave the parser another node?
what am i doing wrong?
thanks in advance

Your xpath & everything else looks right. I have 2 questions...
1 -- what is the length of NodeList nodeList = org.apache.xpath.XPathAPI.selectNodeList(doc, "//*[name() = 'record']"); ?
The answer should be 2, you have 2 record from the XML
2 -- both id of your record is 1. Are you seeing the same value returned because of this? What do you see if you change the second record's id to 2 ??

I need another answer:How can I parse a JRXML file?

it is a network problem, I think the DNS of your provider is not up to date so it cannot find the domain.
There must be a schema declaration at the beginning of your JRXML file. It points to a schema situated on the jasper site (which has changed recently).
The better turnaround is to find this schema, place it on your local file system (or in server's hierarchy) and to change the schema definition in the jrxml file to point to the local file

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");

      default: System.out.println("Sorry Input is Invalid");

If 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;

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

You could have the original face values as integers, thus Ace = 1, Jack = 11 (it'll be easy enough to display the proper values AJQK if you keep your string array and just display whatever corresponds to the value held in your int array).
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)
tofk = true;
if (pair)
// player has a pair
if(tofk)
// player has three of a kind
if(pair && tofk)
// player has a full house

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.
