# Thread: isPrime Boolean Method returns true for squares of primes

1. ## isPrime Boolean Method returns true for squares of primes

```	public boolean isPrime(int x){
if(x % 2 == 0 && x > 2)
return false;
if(x <= 1){
return false;
}
if(x == 2){
return true;
}

for(long i = 3; i < Math.sqrt(x); i+=2){
if(x % i == 0)
return false;
}

return true;```

If I pass through any integer that's a square of a prime number.. It returns with true. So...

Input: 25
Output: "Prime: True"

Input: 49
Output: "Prime: True"

SOLVED: Sorry guys... I just solved it.. Within the For Loop, I never checked for the square root of "x".. So the odd squares would return true..
