Check if Given Number is a Perfect Square in Java

A perfect square is a number that is made by squaring a whole number.

For example:

16 is a perfect square because 42 = 16.
25 is also a perfect square because 52 = 25.

And it goes on and on … .

So now let’s determine in Java if a given number is perfect square or not.

public static String isPerfectSquare(int n) {
	double sqrt=Math.sqrt(n);   
        if ((sqrt - Math.floor(sqrt)) == 0){
	return "Integer "+ n+ " is a Perfect Square";
	return "Integer "+ n+ " is NOT a Perfect Square";


//16 is a Perfect Square
