Default value of an Array

**Calipsio** · April 22nd, 2025, 04:32 AM

" Default value of an Array is null " says my java trainer is it true??
He gave this example :

public class Sample{
    static int[] ar;
    public static void main(String[] args) {
        System.out.println(ar);
    }
}
// Output : null

He said 0 refers to the default int value stored inside the array, which is not exactly the default value of an Array

Please help understand this..

In the code, ar is a reference to an int array. It's value in the code is null because nothing has been assigned to it.
If the code were changed to assign it a value:

  int[] ar = new int[5];

then its value would be a 5 element int array.
Because nothing has been assigned to the individual elements of the array, there values would be 0.
