Error

Question

Why its is an error?

int n = 1000;
int[] a = new int[n*n*n*n];
System.out.println(a.length);

Answer 1

Your n=1000
If you multiply 4 times
Then
1000*1000*1000*1000 which will be =1000000000000 and this number is not in range of int size so enter small number which is under range of int

Answer 2

By the way, instead of n*n*n*n better to use n**4
