I have tried writing a java program to find a number is power of two the one which i mentioned below.

I am passing number as 2147483647 and the output of my program is returning true instead of false.
Can anyone explain what concept I am missing here and how to correct it.

Program

class Solution {
    public boolean isPowerOfTwo(int n) {
        int num = 0;
        int p = 0;
        while(num <= n){
            num = (int) Math.pow(2,p);
            p++;
            if(num == n){
            return true;
        }
        }
        
        return false;    

    }
}

    public static void main(String[] args) {
    
        enter code here
        boolean val = isPowerOfTwo(2147483647);
    
        }
