public class Main { 
    public static void main(String args[]) { 
        int[] arr1; 
        int[] arr2 = new int[3]; 
        char[] arr3 = {'a', 'b'}; 
        arr1 = arr2; /*ww  w .j av a  2  s .  c om*/
        arr1 = arr3; 
        System.out.println(arr1[0] + ":" + arr1[1]); 
    } 
}
  • a 0:0
  • b a:b
  • c 0:b
  • d a:0

Note

Because a char value can be assigned to an int value, you might assume that a char array can be assigned to an int array.

But we're talking about arrays of int and char primitives, which aren't the same as a primitive int or char.

Arrays themselves are reference variables, which refer to a collection of objects of similar type.
