[Solved] Determine if a number is prime [closed]

by


You are missing a bracket. If you keep your code clean it will solve the problem.

Also in your if statement you are checking if number % 2 != 0. If it does not equal to 0 then it could potentially be a prime number. So I changed it to number % 2 == 0 to fix the problem.

The other mistake is that you kept printing even after you knew that the number is not prime. 

public static void isPrime(int number)
    {
        for ( int i = 2; i<Math.sqrt(number) + 1; i ++)
        {
            if ( number%i==0 ) {//If number is not a prime
                //Will print that the number is not a prime once
                System.out.println(number +" is not a prime number.");
                return ; //Will exit the method
            }
        }
        //If you reach this point then the number is prime.
        System.out.println(number +" is a prime number.");
    }
