Regarding PrintWriter

1 New Member
My coding is as follows:

Expand|Select|Wrap|Line Numbers
  1. import java.io.*;
  2. class Sample
  3. {
  4.     public static void main(String args[])
  5.     {
  6.         try
  7.         {
  8.             int[] a = new int[20];
  9.             PrintWriter out = new PrintWriter("EG.txt");
  10.             System.out.println(a.length);
  11.             out.println(a.length);
  12.         }
  13.         catch(FileNotFoundException e)
  14.         {
  15.  
  16.         }
  17.     }
  18. }
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:
Expand|Select|Wrap|Line Numbers
  1. PrintWriter out = new PrintWriter(new FileOutputStream("EG.txt"));
  2.
