how to take large size array in java

Question

i am new to java and i want to take large input size array in java. but in gives me some Runtime Error - NZEC, I don\'t know about it and i also did some research on this error

Answer 1

An array index cannot be specified with a long as you have done but only with an int as the array size is limited to Integer max value

But in your case it should not be a problem as Integer max value is 2^31-1. (more than 2 billions) and you requirement is inferior :10^9 (1 billion).
So it should be fine to replace :

   long n=sc.nextLong();// n can be upto 10^9;

by

   int n=sc.nextInt();// n can be upto 10^9;
