BigInteger for Huge Numbers
Arbitrary-precision integers.
Beyond long
The primitive long can hold values up to about 9.2 quintillion. When you need integers larger than that, Java offers BigInteger from the java.math package, which has no fixed upper limit.
When long Overflows
Exceeding Long.MAX_VALUE silently wraps around to a negative number. This corruption is a classic bug source.
public class Main {
public static void main(String[] args) {
long max = Long.MAX_VALUE;
System.out.println(max);
System.out.println(max + 1);
}
