Array Length in Java

Question

Can anyone help me how I can able to find the logical size of an array like:

int[] ar = new int[10];

ar[0] = 1;

ar[1] = 2;

ar[2] = 3;

ar[3] = 4;

Answer 1

Basically, it will allocated with size 10, and also all the unassigned indexes contains a value of 0 for the datatype int.

I hope this will help.
