Printing array shows wrong output

Question

public class Main{
  public static void main(Strin         


        

Answer 1

The toString() for arrays is broken. You need

import java.util.Arrays;

System.out.println("numbers are" + Arrays.toString(data));

The same applies for Arrays.equals(), Arrays.hashCode(). The Array, Arrays, ArrayUtils classes add functionality you might like arrays to have.

However, you may find that you really want ArrayList instead.
