java - 如何让我的java程序输出答案？

Question

我是 Java 新手，我的类(class)有一项家庭作业，需要一些帮助。我完成了除了输出之外的所有内容，我似乎无法让程序产生答案。

    import java.util.Scanner;
    public class HomeworkScanner
   {

     public static void main(String args[])
     {

            int x, y, z, a, result;
            Scanner Keyboard;
            Keyboard = new Scanner(System.in);
            System.out.println("a = ( x + y ) * z");
            System.out.println("Enter first number for x:");
            x = Keyboard.nextInt(); //
            System.out.println("Enter second number for y:");
            y = Keyboard.nextInt(); //
            System.out.println("Enter third number for z:");
            z = Keyboard.nextInt(); //
            result=a=( x + y ) * z;
         }
    }

        System.out.println("Enter second number for y:");
        y = Keyboard.nextInt(); //
        System.out.println("Enter third number for z:");
        z = Keyboard.nextInt(); //
        result=a=( x + y ) * z;
        System.out.println("result is :"+result);
     }
}
