用Java写一个公司员工管理系统!
今天看发现写管理系统的文章不少，我在这里也给大家用java写一篇！(当然这里只是最简单的那种qwq)
核心功能：对员工各项信息的管理
采用属性文件+资源文件(支持中文简体和英文)
目录
- 第一步：创建一个记录员工信息的文件
- 第二步：循环处理输入的信息
- 第三步：用类及框架来完成对员工内容的管理
事不宜迟，现在就开始吧!
先创建一个Member类
package 管理;
public class Member {
private String name;
private String money;
private String post;
public Member(String name,String money,String post) {
this.name = name;
this.money = money;
this.post = post;
}
@Override
public boolean equals(Object obj) { //完成员工删除和查询的必要方法
if (this == obj) {
return true;
}
if (obj == null) {
return false;
}
if (!(obj instanceof Member)) {
return false;
}
Member mem = (Member) obj;
return this.name.equals(mem.name) && this.money.equals(mem.money) && this.post.equals(mem.post);
}
public String toString() { //输出员工信息的方法
return this.name + ":" + this.money + ":" + this.post + "|";
}
}
为了使程序更加流畅，再加一个垃圾处理的线程Optimization
package 管理;
public class Optimization extends Thread {
private String title;
private int number;
private int wait;
public Optimization(String title,int number,int wait) {
this.title = title;
this.number = number;
this.wait = wait;
}
@Override
public void run() {
Runtime runtime =Runtime.getRuntime();
System.out.println("[IO]name:" + this.title + ",member：" + this.number);
while (true) {
runtime.gc();
try {
Thread.currentThread().sleep(this.wait);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
最后创建主类 ManagementSystem
package 管理;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.io.PrintWriter;
import java.util.ArrayList;
import java.util.List;
import java.util.ResourceBundle;
import java.util.Scanner;
public class ManagementSystem {
public static void main(String args[]) throws Exception{
ResourceBundle resource = ResourceBundle.getBundle("管理.config");
System.out.println(resource.getString("info.1"));
new Optimization("Optimization",10,10000).start();
System.out.println(resource.getString("info.2"));
List<Member> all = new ArrayList<Member>();
System.out.println(resource.getString("info.3"));
File file = new File("./managementsystem");
File read = new File("./managementsystem/info.txt");
System.out.println(resource.getString("info.4"));
if (file.exists()) {
if (read.exists()) {
try {
System.out.println(resource.getString("info.5"));
InputStream input = new FileInputStream(read);
byte data [] = input.readAllBytes();
String str = new String(data);
String result[] =str.split("\\|");
for (int x = 0; x < result.length; x ++) {
String temp[] = result[x].split(":");
all.add(new Member(temp[0], temp[1], temp[2]));
}
} catch(Exception e) {
if (read.exists()) {
read.delete();
}
System.out.println(resource.getString("info.6"));
System.exit(1);
}
System.out.println(resource.getString("info.7"));
} else {
System.out.println(resource.getString("info.8"));
read.createNewFile();
System.out.println(resource.getString("info.9"));
all.add(new Member("try" , "0", "try"));
}
} else {
file.mkdir();
System.out.println(resource.getString("info.8"));
read.createNewFile();
System.out.println(resource.getString("info.9"));
all.add(new Member("try" , "0", "try"));
}
PrintWriter pu = new PrintWriter(new FileOutputStream(read));
System.out.println(resource.getString("info.10"));
System.out.println(resource.getString("info.11"));
while (true) {
System.out.println(resource.getString("info.12"));
Scanner scanner = new Scanner(System.in);
int i = scanner.nextInt();
int n = 0;
try {
switch (i) {
case 0:
System.out.print(resource.getString("info.13"));
break;
case 1:
System.out.print(resource.getString("info.14"));
Scanner scanner1 = new Scanner(System.in);
String name = scanner.next();
System.out.print(resource.getString("info.25"));
Scanner scanner2 = new Scanner(System.in);
String member = scanner.next();
System.out.print(resource.getString("info.26"));
Scanner scanner3 = new Scanner(System.in);
String card = scanner.next();
all.add(new Member(name, member, card));
System.out.println(resource.getString("info.27"));
break;
case 2:
System.out.print(resource.getString("info.15"));
Scanner scanner11 = new Scanner(System.in);
String name1 = scanner.next();
System.out.print(resource.getString("info.25"));
Scanner scanner12 = new Scanner(System.in);
String member1 = scanner.next();
System.out.print(resource.getString("info.26"));
Scanner scanner13 = new Scanner(System.in);
String card1 = scanner.next();
all.remove(new Member(name1, member1, card1));
System.out.println(resource.getString("info.28"));
break;
case 3:
System.out.print(resource.getString("info.16"));
all.forEach(System.out::println);
System.out.print(resource.getString("info.17"));
break;
case 4:
System.out.print(resource.getString("info.18"));
Scanner scanner21 = new Scanner(System.in);
String name2 = scanner.next();
System.out.print(resource.getString("info.25"));
Scanner scanner22 = new Scanner(System.in);
String member2 = scanner.next();
System.out.print(resource.getString("info.26"));
Scanner scanner23 = new Scanner(System.in);
String card2 = scanner.next();
if (all.contains(new Member(name2, member2, card2))) {
System.out.println(resource.getString("info.19"));
} else {
System.out.println(resource.getString("info.20"));
}
break;
case 5:
System.out.println("=====ManagementSystem=====");
System.out.println("=====author: Yaoboyu======");
System.out.println("===version: beta1.00.1====");
System.out.println("=====language: zh_CN======");
System.out.println("==Thanks for using this!==");
break;
case 6:
System.out.println(resource.getString("info.22"));
all.forEach(pu::print);
pu.close();
System.out.println(resource.getString("info.23"));
System.out.println(resource.getString("info.24"));
System.exit(i);
}
} catch(Exception e) {
break;
}
}
}
