用JAVA程序编写一道：求一长方体的体积，（长3宽4高5）

Answer 1

package com.tmgps.test;

import java.util.Scanner;

public class test {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入长方体的长");
int a=input.nextInt();
System.out.println("请输入长方体的宽");
int b=input.nextInt();
System.out.println("请输入长方体的高");
int c=input.nextInt();
System.out.println("长方体的体积为："+a*b*c);

}

}

长宽高都可以自己输入

Answer 2

class Test{
public int getNum(int length,int width,int hieght){
int num = length*width*height;
return num;
}
public static void main (int[] args){
int numTest = new Test().getNum(3,4,5);
System.out.println("体积为："+numTest);
}

}

Answer 3

int length = 3;
int width = 4;
int height = 5;
System.out.println("长方体的体积是："+(length*width*height));

Answer 4

public class CalculateRect{
public static void main(String[] args){
int a = 3;
int w = 4;
int h = 5;
int volume = calculate(a,w,h);
Ssystem.out.println("体积为:" + volume);

}
private static int calculate(int a.int w,int h){
return a*w*h;

}

}
