Question

Java编程，在程序制定三个数，计算并输出平均值及三个数乘积。

考试中 求大侠速度回答

Answer 1

public class Test  {
	public static void main(String[] args) {
	   //定义三个变量，并且赋初值
	   int a=5;
	   int b=4;
	   int c=3;
	   //输出平均值
	   System.out.println((a+b+c)/3);
	   //输出三个数乘积
	   System.out.println(a*b*c);
	}
	
}

Answer 2

import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);// 获取键盘输入
double a = sc.nextDouble();
double b = sc.nextDouble();
double c = sc.nexDouble();
System.out.println("The average of the input is:"+(a+b+c)/3.0);
System.out.println("The multi of the input is:"+(a*b*c));
}

Answer 3

考试还可以这样？

public class Test {

public static void main(String[] args) {
int a = 3;
int b = 15;
int c = 20;

double avergae = (double)(a + b + c) / 3;
long mul = a * b * c;

System.out.println("平均" + avergae);
System.out.println("乘积" + mul);

}

}
