Java, static and instance methods with same name

My code will start on of following Line445

I currently working on my college assignment and as part of requirement,

I must make some of static and instance methods with having same name.

Such as I require to make both instance/static methods named isPrime()

What should I do?

Edit/Add/Screenshot
It worked!

 // class
    public class MyInteger {
        // Field
        private int num;

        public MyInteger(int someNum){
            num = someNum;
        }

        //Method

        private void setNum(int setNum){
            num = setNum;
        }

        public int getNum(int getNum){
            return getNum;
        }
        public int toInteger(){
            num = Integer.valueOf(num);
            return num;
        }

        public boolean isPrime(){

            if (num < 2){
                //prime number must be larger than 1
                return false;
            }
            for (int i = 2; i < num; i++){
                //if any number result 0 reminder until self, it is not prime
                if(num %  i == 0){
                    return false;
                }
            }
            return true;
        }


    }

You can make two methods with the same name so long as their parameters (the input from the brackets) are different. So for example you could have

public boolean isPrime() { ... }
public static boolean isPrime(int num) { ... }

but not

public boolean isPrime() { ... }
public static boolean isPrime() { ... }
