Ok, I am having a problem receiving a value... I have been researching for several days, but nothing has hit the topic I need. It is a mastermind game. I am creating this for a Final project in my High School programming class. The Eclipse Compiler is telling me that in cannot be resolved. How do I fix this and Accomplish my goal. This is not being run in an applet. 

```
package masterMind;

import java.util.Scanner;

public class MasterMind {

    public static void main(String[] args) {
        System.out.println("This is MasterMind, a logic game");
        System.out.println("To win you must guess correctly where each number is");
        System.out.println("You will be told if you get one correct");
        System.out.println("You will only get 10 tries, then you lose");
        System.out.println("Lets begin");

        //Change this value to change the game
                int m1=2;
                int m2 =3;
                int m3=2;
                int m4=1;
        //Create Board
        System.out.println("__ __ __ __");

        Scanner UserGuess = new Scanner(System.in);
        int num = in.nextInt();

```

I have very limited Coding knowledge, so please keep it simple and explain
