如何獲取我的Java程序以輸出答案？

Question

我是java的新手，我的課程有一個家庭作業，需要一點幫助。 我完成了除輸出以外的所有操作，似乎無法獲得產生答案的程序。

    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;
         }
    }

Answer 1

我假設您想要的格式為“結果= a”，這將是

System.out.println("Result = " + result);

或者您可以使用a因為您將它們設置為相同的值

Answer 2

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("result is :"+result);
     }
}

Answer 3

您可以只使用System.out.println("Result: "+result); 在控制台中打印result 。
