用Java编写一个程序,输入a.b.c三个值,输出三个数的和及乘积，急求

如题所述

package test;

import java.util.Scanner;

public class Demo1 {

public static void main(String[] args) {

System.out.println("请输入第一个值:");

Scanner scan = new Scanner(System.in);

int a = scan.nextInt();

System.out.println("请输入第二个值:");

scan = new Scanner(System.in);

int b = scan.nextInt();

System.out.println("请输入第三个值:");

scan = new Scanner(System.in);

int c = scan.nextInt();

System.out.println("三个数之和为:" + (a + b + c));

System.out.println("三个数之积为:" + (a * b * c));

}

}

棒棒哒
