Need help with a Java code

The Question is The Program needs to do this:

1. User enters two integers

2. Program finds closest integer to 21

3. Eliminate if over 21

What I have coded so far:

import java.util.Scanner;

public class MathMethods { public static void main(String[] args) {

System.out.println("Hello to all of you users.");

int num1 = getNum(); int num2 = getNum(); int perfectNum=0; boolean num1Equal=checkNumEqual(num1); boolean num2Equal=checkNumEqual(num2); if (num1Equal) { perfectNum=num1; printValue(perfectNum); }else if(num2Equal) { perfectNum=num2; printValue(perfectNum); } int num1Diff=getDiff(num1); int num2Diff=getDiff(num2);

}

public static int getNum() { Scanner input = new Scanner(System.in); System.out.println("Enter a number"); return input.nextInt(); }

public static boolean checkNumEqual(int num) { boolean ans = false; if (num == 21) { ans = true; } return ans; } public static void printValue(int num) { System.out.println("Your number is;"); System.out.println(num); System.exit(0); } public static int getDiff(int num1) { return (21-num1); } public static boolean IsLargerThan21(int num1) { return (21-num1<=0); } public static int getSmaller(int num1, int num2) { return Math.min(num1, num2); }

}
