class YG implements ComparableYG{//员工类,实现比较接口

String name;//姓名

int gz;//工资

public YG(String name, int gz) {

this.name = name;

this.gz = gz;

}

public String toString() {

return "姓名:"+name+"\t工资:"+gz;

}

public int compareTo(YG o) {//通过这个方法, 实现按工资排序

return o.gz-this.gz;//从大到小

}

}

public class MyTest {

public static void main(String[] args) {

YG[] ary = new YG[5];

ary[0] = new YG("张三", 5260);

ary[1] = new YG("赵四", 6000);

ary[2] = new YG("王五", 5500);

ary[3] = new YG("唐六", 5800);

ary[4] = new YG("杨七", 5200);

Arrays.sort(ary);//排序

double sum = 0;

for (YG yg : ary) {

sum+=yg.gz;

}

System.out.println("最高工资:"+ary[0]+"\n平均工资:"+sum/ary.length);

}

}

输出

最高工资:姓名:赵四 工资:6000

平均工资:5552.0

求一段简单的JAVA代码 要求员工工资管理系统的一个增删改查代码，谢谢了

对数据库进行增删改查？

以下是 sql server 2013+java.实现的是对MSC对象的增删改查.

需要下载连接驱动程序：com.microsoft.sqlserver.jdbc.SQLServerDriver

网上搜一下就行

java计算工资

person类：

public abstract class Person {

public double pay; // 总工资

public int hour; // 课时

public double countPay(int hour) {

return pay;

}

}

助教类：

public class Assistant extends Person {

public final double BASE_PAY = 800; // 基本工资

public final double HOUR_PAY = 25; // 每课时的费用

public double countPay(int hour) {

pay = BASE_PAY + hour * HOUR_PAY;

return pay;

}

}

讲师类：

public class Instructor extends Person {

public final double BASE_PAY = 1000; // 基本工资

public final double HOUR_PAY = 35; // 每课时的费用

public double countPay(int hour) {

pay = BASE_PAY + hour * HOUR_PAY;

return pay;

}

}

副教授类：

public class AssistantProfesson extends Person {

public final double BASE_PAY = 1200; // 基本工资

public final double HOUR_PAY = 40; // 每课时的费用

public double countPay(int hour) {

pay = BASE_PAY + hour * HOUR_PAY;

return pay;

}

}

教授类：

public class Professor extends Person {

public final double BASE_PAY = 1400; // 基本工资

public final double HOUR_PAY = 50; // 每课时的费用

public double countPay(int hour) {

pay = BASE_PAY + hour * HOUR_PAY;

return pay;

}

}

测试类：

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class Test {

public static void main(String[] args) {

System.out.println("人员类型如下：");

System.out.println("1 = 助教\r\n2 = 讲师\r\n3 = 副教授\r\n4 = 教授");

System.out.print("请选择：");

BufferedReader personType = new BufferedReader(new InputStreamReader(

System.in));

String type = null;

int hour = 0;

try {

type = personType.readLine();

} catch (Exception e) {

e.printStackTrace();

}

if (type.matches("[1-4]{1}")) {

switch (Integer.valueOf(type)) {

case 1:

hour = getHour();

if(hour == 0){return;}

Person p1 = new Assistant();

double pay1 = p1.countPay(hour);

System.out.println("助教工作" + hour + "课时的工资为：" + pay1);

break;

case 2:

hour = getHour();

if(hour == 0){return;}

Person p2 = new Instructor();

double pay2 = p2.countPay(hour);

System.out.println("讲师工作" + hour + "课时的工资为：" + pay2);

case 3:

break;

case 4:

if(hour == 0){return;}

Person p4 = new Professor();

double pay4 = p4.countPay(hour);

System.out.println("教授工作" + hour + "课时的工资为：" + pay4);

break;

}

} else {

System.out.println("输入数据错误！程序提前推出！");

return;

}

}

public static int getHour() {

System.out.print("请输入工作时间：");

BufferedReader hours = new BufferedReader(new InputStreamReader(

System.in));

String strHour = null;

int hour = 0;

try {

strHour = hours.readLine();

} catch (Exception e) {

e.printStackTrace();

}

if (strHour.matches("^[0-9]+?")) {

} else {

}

return hour;

}

}

怎样计算工资包括年工资,周工资,月工资，用java编写程序

代码一

public double earnings()

{double a=50000.456;

return a;

}

代码二

public double earnings()

{double b=2000;

return 12*b;}

代码三

public double earnings()

{double c=500;

return 52*c;}

代码四

我也正在思考中
