用java编写一个某公司员工数组中添加新的员工,以及对员工信息的维护.

你这个设计我忍不住想吐槽一下：

1、假设你又好些个公司，难道每个公司的员工号都不一样吗？

2、使用数组的方式添加员工，当查询的时候，如果员工数量较大，查询和删除等 *** 作比较麻烦。

1）每个员工的信息包括：编号、姓名、性别、出生年月、学历、职务、电话、住址等。

（2）系统的功能包括：

（a）查询：按特定条件查找员工。

（b）修改：按编号对某个员工的某项信息进行修改。

（c）插入：加入新员工的信息。

（d）删除：按编号删除已离职员工的信息。

（e）排序：按特定条件对所有员工的信息进行排序。

Employee类:

public class Employee {

private int id

private String name

private int age

private String email

public int getId() {

return id

}

public void setId(int id) {

this.id = id

}

public String getName() {

return name

}

public void setName(String name) {

this.name = name

}

public int getAge() {

return age

}

public void setAge(int age) {

this.age = age

}

public String getEmail() {

return email

}

public void setEmail(String email) {

this.email = email

}

}

Manager类:

import java.util.ArrayList

import java.util.List

public class Manager {

public static List<Employee>employees = new ArrayList<Employee>()

public static void addEmployee(Employee employee){

employees.add(employee)

}

public static void deleteEmployee(Employee employee){

employees.remove(employee)

}

public static void updateEmployee(Employee employee){

int len = employees.size()

for(int i=0i<leni++){

Employee e = employees.get(i)

if(e.getId() == employee.getId()){

deleteEmployee(e)

addEmployee(employee)

}

}

}

public static Employee selectEmployeeById(int id){

int len = employees.size()

if(len!=0){

Employee emp = new Employee()

for(int i=0i<leni++){

Employee e = employees.get(i)

if(e.getId() == id){

emp = e

}

}

return emp

}else{

return null

}

}

public static Employee selectEmployeeByName(String name){

int len = employees.size()

if(len!=0){

Employee emp = new Employee()

for(int i=0i<leni++){

Employee e = employees.get(i)

if(e.getName().equals(name)){

emp = e

}

}

return emp

}else{

return null

}

}

public static void printEmployees(){

int len = employees.size()

if(len != 0){

for(int i=0i<leni++){

System.out.println(employees.get(i).getId()+":\t"+

employees.get(i).getName()+"\t"+

employees.get(i).getAge()+"\t"+

employees.get(i).getEmail())

}

}else{

System.out.println("无员工")

}

}

}

测试EmpManaTest类：

public class EmpManaTest {

public static void main(String[] args) {

Employee e = new Employee()

e.setId(1)

e.setName("zz")

e.setAge(20)

e.setEmail("zz@163.com")

Manager.addEmployee(e)

Employee e2 = new Employee()

e2.setId(2)

e2.setName("scof")

e2.setAge(18)

e2.setEmail("scofield@mail.com")

Manager.addEmployee(e2)

System.out.println("添加员工后：")

Manager.printEmployees()

System.out.println("----------------------------------------------")

Employee emp = new Employee()

emp.setId(1)

emp.setName("virus")

emp.setAge(30)

emp.setEmail("virus@163.com")

Manager.updateEmployee(emp)

System.out.println("修改员工后：")

Manager.printEmployees()

System.out.println("----------------------------------------------")

System.out.println("查询员工ByID：")

Employee empSelectId = Manager.selectEmployeeById(1)

System.out.println(empSelectId.getName())

System.out.println("----------------------------------------------")

System.out.println("查询员工ByName：")

Employee empSelectName = Manager.selectEmployeeByName("virus")

System.out.println(empSelectName.getEmail())

System.out.println("----------------------------------------------")

System.out.println("删除一个员工后：")

Manager.deleteEmployee(emp)

Manager.printEmployees()

}

}

这个是不是你想要的...........
