What is the modulo operator for longs in Java?

Question

How do I find the modulo (%) of two long values in Java? My code says \'Integer number too large\' followed by the number I\'m trying to mod. I tried casting it to a long bu

Answer 1

You can only have an integer up to 2 147 483 647. If you want to go bigger than that, say 3 billion, you must specify it to be a long

class Descartes {
    public static void main(String[] args) {
        long orig = Long.MAX_VALUE;
        long mod = orig % 3000000000; // ERROR 3000000000 too big
        long mod = orig % 3000000000L; // no error, specified as a long with the L
    }
}

Keep in mind that you can use capital OR lowercase L, but it's advisable to use capital, since the lowercase looks remarkably similar to the number 1.
