Checks if the bit at position pos of an integer n is set. - Java java.lang

Description

Checks if the bit at position pos of an integer n is set.

Demo Code

//package com.java2s;

public class Main {
    public static void main(String[] argv) throws Exception {
        int n = 2;
        int pos = 2;
        System.out.println(isBitSet(n, pos));
    }/*from ww w .j  a v a 2 s .  c  o  m*/
