issue in file io

hello all

i am doing a copy operation from a file to another file.in source file i have 13 digit no but in destination file there is only 12 digit copied.code is as follows.

Code:

---

public void createOriganalFile() {
    try {
   
    File ObjInputFile1 = new File(strFilepath + "_dummy.txt");
    File ObjOutputFile1 = new File(strFilepath);
    String strLine1 = "";
    BufferedReader ObjBufferReaderIn1 = new BufferedReader(new FileReader(ObjInputFile1));
    BufferedWriter ObjBufferReaderOut1 = new BufferedWriter(new FileWriter(ObjOutputFile1));
    do {
    if ((strLine1 = ObjBufferReaderIn1.readLine()) == null) {
    System.out.println("strLine1 is null");
    break;
    }
    System.out.println("strLine--------- " + strLine1 +" strFilepath " + strFilepath);
    ObjBufferReaderOut1.write(strLine1,0,13);
    ObjBufferReaderOut1.newLine();
    ObjBufferReaderOut1.flush();
    System.out.println("Here After: "+strLine1);//13 digit no
   
   
   
    } while (true);
   
    //ObjInputFile.delete();
    ObjBufferReaderIn1.close();
    ObjBufferReaderOut1.close();
    ObjBufferReaderIn2.close();
    } catch (Exception ex) {
    ex.printStackTrace();
    }
    }

Works OK for me.

Incidentally, why have a 'do' loop forever with a break check, instead of just a simple while loop ? e.g.

Code:

---

while ((strLine1 = objBufferReaderIn1.readLine()) != null) {
  ...
  ...
}

p.s. Java Naming Conventions are that class names start with an uppercase letter, method and variable names start with a lowercase letter.

yes you are right.I have made the changes according to you.it is running same in my window system.but why it is not running in RHEL 5
