Look at the following code. It is intended to identify prime numbers (i.e. numbers that cannot be divided by any number smaller than themselves (other than 1). However, there are logic problems -- the Boolean logic is not implemented properly. Explain how the method could be modified to print out a single line of output that states whether or not the input argument is a "divisible" (able to be divided by a smaller number) number or not (i.e. if it is not a divisible number, it would be a prime number).

public static void mystery(int x){

int x1 = 10; int z = 5;

while (z * 2 <= x1) {

z++;

}

System.out.println("y = " + y + " and z = " + z); } }
