private String name;

private String department;

private double salary;

//构造方法

public Employee(String name, String department, double salary) {

this.name = name;

this.department = department;

this.salary = salary;

}

public String toString() {

return "姓名:" + name + "\t部门:" + department + "\t工资:" + salary;

}

public void raiseSalary(double per) {

this.salary = salary + salary * per;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public String getDepartment() {

return department;

}

public void setDepartment(String department) {

this.department = department;

}

public double getSalary() {

return salary;

}

public void setSalary(double salary) {

this.salary = salary;

}

}

public class TestEmployee {//测试类

public static void main(String[] args) {

Employee e1 = new Employee("张三", "技术开发部", 5000);

Employee e2 = new Employee("赵四", "后勤服务部", 3800);

Employee e3 = new Employee("王五", "产品营销部", 6800);

System.out.println(e1 + "\n" + e2 + "\n" + e3);

double per = 0.07;

e1.raiseSalary(per);

e2.raiseSalary(per);

e3.raiseSalary(per);

System.out.println("==============加薪7%===============");

System.out.println(e1 + "\n" + e2 + "\n" + e3);

}

}

输出

姓名:张三 部门:技术开发部 工资:5000.0

姓名:赵四 部门:后勤服务部 工资:3800.0

姓名:王五 部门:产品营销部 工资:6800.0

==============加薪7%===============

姓名:张三 部门:技术开发部 工资:5350.0

姓名:赵四 部门:后勤服务部 工资:4066.0

用java,编写五个人的工资表,计算出最高工资,平均数

import java.util.Arrays;

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

使用java编写程序实现输入员工工资,获得员工的平均工资,要求使用象数组类型的

一：将员工姓名、工资封装成一个对象

public class Staff {

private String name;

private int salary;

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getSalary() {

return salary;

}

public void setSalary(int salary) {

this.salary = salary;

}

public Staff(String name, int salary) {

super();

this.name = name;

this.salary = salary;

}

}

二：初始化一个数组，算平均工资

public class Average {

public static void main(String[] args) {

Staff staffs[] = {new Staff("zhangsan", 1000), new Staff("lisi", 1100), new Staff("wangwu", 1200)};

int sum = 0;

for(Staff staff : staffs) {

sum = sum + staff.getSalary();

}

System.out.println("员工人数：" + staffs.length + " 总工资：" + sum + " 平均工资：" + sum / staffs.length);

}

}

用JAVA编写一个处理学院员工月薪的应用程序的代码是什么？

abstract class Person{

private String name;

private String post;

Person(String name,String post){

this.name = name;

this.post = post;

}

public String getID(){

return (name+""+post);

}

public abstract double counting();

public void setName(String name){

this.name = name;

}

public String getName(){

return this.name;

}

public void setPost(String post){

this.post = post;

}

public String getPost(){

return this.post;

}

}

class Leader extends Person{

Leader(String name,String post){

super(name,post);

}

public double counting(){

return 3000d;

}

}

class Management extends Person{

private double basicWage=0d; //基本工资

private double allowance=0d; //津贴

Management(String name,String post){

super(name,post);

}

public void setBasicWage(double basicWage){

this.basicWage = basicWage;

}

public double getBasicWage(){

return this.basicWage;

}

public void setAllowance(double allowance){

this.allowance = allowance;

}

public double getAllowance(){

return this.allowance;

}

public double counting(){

return this.basicWage+this.allowance;

}

}

class Teacher extends Person{

private int hours; //课时

static final double ASSISTANT_STANDARD = 35.0d;//助教的课时收费标准

static final double LECTOR_STANDARD = 45.0d;//讲师的课时收费标准

static final double ANOTHER_STANDARD = 55.0d;//其他课时收费标准

Teacher (String name,String post){

super(name,post);

}

public double counting(){

double wage; //工资

if(this.getPost().equals("助教")){

wage = ASSISTANT_STANDARD*hours;

}else if(this.getPost().equals("讲师")){

wage = LECTOR_STANDARD * hours;

}else{

wage = ANOTHER_STANDARD * hours;

}

return wage;

}

public void setHours(int hours){

this.hours = hours;

}

public int getHours(){

return this.hours;

}

}

class Test {

public static void main(String [] args){

Leader leader = new Leader("张三","领导");

System.out.println(leader.getName()+"工资为:"+leader.counting());

Management manage = new Management("李四","管理人员");

manage.setBasicWage(1000d);

manage.setAllowance(500d);

System.out.println(manage.getName()+"工资为:"+manage.counting());

Teacher teacher = new Teacher("王五","助教");

teacher.setHours(50);

System.out.println(teacher.getName()+"工资为:"+teacher.counting());

Teacher teacher1 = new Teacher("赵六","讲师");

teacher1.setHours(60);

System.out.println(teacher1.getName()+"工资为:"+teacher1.counting

());

}

}

看下吧,有什么不足的请指出来
