生成项目错误：找不到符号

Question

I am getting these two errors. Error: Could not find or load main class Dice Build project error: cannot find symbol

My file is saved as Dice.java. I checked because that was one of my problems with my last program. As far as the symbol error I am not sure.

public class Dice{ <---class is Dice

public static void main(String[] args) {

// Welcome message.
    System.out.println ("Welcome to The Dice Roller Game!");

// Roll the dice.

        int die1, die2;
        int rollcount;
        rollcount = 0;
    int wins = 0;   

Scanner keyboard = new Scanner(System.in); <----line 13 symbol error

This is just a portion of the source code.

import java.util.Scanner;

public class Dice {
