2. 设置四维数组stu[70][4]分别是:学生 语文 数学 外语 平均

，chinaMax,englishMax,mathMAx分别放各科最高分，循环数组分别求出。

class CountGrade{

static public void main(String[] str){

int[][] stu=new int[70][4];

int chinaMax,englishMax,mathMAx;

int tmp;

...输入成绩;

chinaMax=englishMax=mathMax=0;

for(int i=0;i70;i++)

for(int j=0;j4;j++)

{

if(j3) {tmp=tmp+stu[i][j];}

else stu[i][j]=tmp/3;

if(j==0 chinaMaxstu[i][j]) chinaMax=stu[i][j];

if(j==1 englishMaxstu[i][j]) englishMax=stu[i][j];

if(j==2 mathMaxstu[i][j]) mathMax=stu[i][j];

}

for(int k=0;k70;k++)

System.out.println(stu[k][3]); //平均分

System.out.println(chinaMax);

System.out.println(englishMax);

System.out.println(mathMax);

}

}

运行结果：

[测试一]Employee 员工基本信息：

[测试二]SalariedEmployee 周薪承继调用：

姓名：小二

年龄：18

社保号码：2013100002

周薪：1200.0元

[测试三]HourlyEmployee 基本工资+工作时间承继调用：

姓名：张三

年龄：30

社保号码：2014100003

周薪：400.0元

周薪：50.0小时

[测试四] CommissionEmployee 对象应当有佣金率和销售总额：：

姓名：李四

年龄：33

社保号码：2009100004

佣金率： 23.0%

总销售额：33405.0元

[测试五] BasePlusCommissionEmployee 对象应当有对应的基本工资：：

姓名：陈五

年龄：40

社保号码：200110005

基本工资：3800.0元

-----------------运行结束-----------------------

[备注]：大哥，因为不是很理解上面的应用，假如需要计算的话，你可以自己修改一下代码算法。基本的架构都已经搭建了，采用构造类和承继方法进行，你把这几个文件都分开存放在一个文件夹下面就可以了。运行Text.java 这个文件。

这些都是自己写的，希望能给予你参考作用。

求解一道java题，谢谢。

代码如下，说明几点：

1.共有6个文件，五个类和一个测试文件

2.有些类的命名可能打的不一样，比如掉了个ee之类的，不过很好看出来

3.为了利于实现，没有使用java自带的toString,而是自定义了个toStr.

一道Java编程题，急，在线等。

这个题目说明

:

1

编写包含员工名称及工资属性的

超类

，并实现一个返回float/double类型的print()方法

这个的

构造器

我没实际写过，不知道继承的父类要不要全部包含子类构造器。你自己在实现子类时再来改吧

2

编写四个

Employee

的子类。

每个子类的构造器不能用默认无参构造器，必须使用有参的构造器

同时子类有各自的属性，比如

计件工

的数量，计时工的时间等等。

并重写print()方法，按要求的

逻辑

返回应得工资金额

大概就是这样。只是

具体实现逻辑题目没写。你的重写的print()方法逻辑可以简单点。大概一下就行

比如只返回每月工资，

计件的数量随便给个就是。
