How to store a very large integer in java

Question

My input is of 10^19 ; How can i store this number.

int input ; // Of order 10^19;
int answer = input%(10^10+3)

How to perform above operations and what if i want to have an array

A[input][input] // showing me an error

please note that `^` operator is **bitwise XOR** and not actually powering — EpicPandaForce, Sep 11 '14 at 12:44

Instead of int, declare it as long. Its maximum value is of 2^63-1
