You maye need something like this :

 
File file= new File("numberfile");
PrintStream pin = new PrintStream(new BufferedOutputStream(newFileOutputStream(file.toString(), true)),true);
System.setOut(pin);
for(i=0;i<arrsize;i++)
{
 System.out.println("the number  is "+arr[i]);
}

You may also want to use the )]Arrays.toString() method, which exists since Java 1.5:

import java.util.Arrays;
 
public class ArrayWriter {
   public static void main(String[] args) {
      int[] myArray = {2,463,324,86,3,1,87};
      System.out.println(Arrays.toString(myArray);
   }
}

will print the array in a nice readable way. Of course, you can also write that into a file.
