Hello Everybody,

I want to break the paragraph into lines and want to store it in an array.
I can not use APLIT function...somehow its not available. I'm using Java 1.3.1
I know stringtikenizer can do it but it break the lines by default on "SPACE" also. I want to eliminate that.

Following the type of paragraph I want to break into lines.

-- -----------------------------------------------
-- Query from table AUTOMATION.EMPLOYEE

SELECT
     A.EMPNO, A.FIRSTNME, A.MIDINIT,
     A.LASTNAME, A.WORKDEPT, A.PHONENO,
     A.HIREDATE, A.JOB, A.EDLEVEL,
     A.SEX, A.BIRTHDATE, A.SALARY,
     A.BONUS, A.COMM
FROM
     AUTOMATION.EMPLOYEE A
 


Thanks,

This will retun an array of String, given a String input:

      static String[] breakStringOnNewline(String s) {
            ArrayList result = null;
            try {
                  result = new ArrayList();
                  BufferedReader in = new BufferedReader(new StringReader(s));
                  String line = null;
                  while ((line = in.readLine()) != null) {
                        result.add(line.trim());
                  }
            }
            catch (IOException e) {
                  e.printStackTrace();
                  return null;
            }
            return (String[])result.toArray(new String[result.size()]);
      }
