用Java写一个公司员工管理系统!

用Java写一个公司员工管理系统!

今天看CSDN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;

	            	all.remove(new Member(name1, member1, card1));
	            	System.out.println(resource.getString("info.28"));
	            	break;

	            	if (all.contains(new Member(name2, member2, card2))) { 
	            		System.out.println(resource.getString("info.19"));
	            	} else {
