Regarding PrintWriter

Oct 23 '10, 07:00 AM

My coding is as follows:

Code:

import java.io.*; class Sample { public static void main(String args[]) { try { int[] a = new int[20]; PrintWriter out = new PrintWriter("EG.txt"); System.out.println(a.length); out.println(a.length); } catch(FileNotFoundException e) { } } }

After compilation and execution, in the Console i get 20 but in the file 'EG.txt' i get nothing. It is empty. What went wrong?

You need to modify the PrintWriter constructor, PrintWriter constructor needs and OutputStream object, not the String to the text file.

you can do:

Code:

PrintWriter out = new PrintWriter(new FileOutputStream("EG.txt"));
