薪酬管理系统（主要是从文件中读，并且写到文件中）

薪酬管理系统（主要是从文件中读，并且写到文件中）

分为三个类Employee、Emp_Manage、MainTest类

1. Employee主要实现创建一个用户

   /**
    * 
    * @author LvGJ
    * 只用基础的getter和setter
    *
    */
   public class Employee {
   	String name;
   	int age;
   	double salary;
   	public Employee(){
   		
   	}
   	public Employee(String name,int age,double salary){
   		this.name = name;
   		this.age = age;
   		this.salary = salary;
   	}
   	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 double getSalary() {
   		return salary;
   	}
   	public void setSalary(double salary) {
   		this.salary = salary;
   	}
   	@Override
   	public String toString(){
   		return "姓名："+this.name+"\n年龄："+this.age+"\n工资："+this.salary;
   	}
   	public String toFile(){
   		return this.name+","+this.age+","+this.salary;
   	}
   }
   

2. Emp_Manage类主要实现对员工的管理

   /**
    * 
    * @author LvGJ
    * 其中的init()是用来将文件中的数据读取到List中
    * 
    */
   public class Emp_Manage {
   	private List<Employee> ls;
   	private File ef;
   	public Emp_Manage(){
   		ef = new File("Employee.txt");
   		ls = new ArrayList<Employee>();
   		init();
   	}
   	private void init(){
   		try{
   			BufferedReader br = new BufferedReader(new FileReader(ef));
   			String tmp = "";
   			while((tmp = br.readLine())!=null){
   				String[] info = tmp.split(",");
   				ls.add(new Employee(info[0],Integer.parseInt(info[1]),Double.parseDouble(info[2])) {
   				});
   			}
   			br.close();
   		}catch(Exception e){
   			e.printStackTrace();
   		}
   	}
   	public void add(Employee e){
   		ls.add(e);
   		System.out.println("添加成功！");
   		String tmp = e.toFile();
   		try{
   			BufferedWriter bw = new BufferedWriter(new FileWriter(ef,true));
   			bw.write(tmp+"\n");
   			System.out.println(tmp);
   			bw.flush();
   			bw.close();
   		}catch(Exception ex){
   			ex.printStackTrace();
   		}
   		
   	}
   	public void deleByEmp(Employee e){
   		for(int i = 0;i<ls.size();i++){
   			if(ls.get(i).getName().equals(e.getName())){
   				ls.remove(i);
   				System.out.println("删除成功！");
   				break;
   			}
   			if(i==ls.size()-1)
   				System.out.println("无该用户！");
   		}
   	}
   	public void deleByName(String name){
   		for(int i = 0;i<ls.size();i++){
   			if(ls.get(i).getName().equals(name)){
   				ls.remove(i);
   				System.out.println("删除成功！");
   				break;
   			}
   			if(i==ls.size()-1)
   				System.out.println("无该用户！");
   		}
   	}
   	public void findEmp(String name){
   		for(Employee e:ls){
   //			System.out.println(e.getName());
   			if(e.getName().equals(name)){
   				System.out.println(e.toString());
   				return ;
   			}
   		}
   		System.out.println("查无此人！");
   	}
   	public void showAll(){
   		for(Employee e : ls){
   			System.out.println(e.toString());
   			System.out.println();
   		}
   	}
   }
   

3. MainTest类用于测试

   public class MainTest {
   	public static void main(String[] args) {
   		int op = -1;
   		Emp_Manage ema = new Emp_Manage();
   		Scanner s = new Scanner(System.in);
   		while(op!=0){
               System.out.println("薪酬管理系统");
               System.out.println("---------------------------------------");
               System.out.println("1.添加新员工");
               System.out.println("2.显示所有员工信息");
               System.out.println("3.根据工号删除该员工的信息");
               System.out.println("0.结束！");
               System.out.println("---------------------------------------");
               System.out.println("请选择序号：");
               op = s.nextInt();
               
               if(op==1){
               	System.out.println("请输入姓名：");
               	String name = s.next();
               	
               	System.out.println("请输入年龄：");
               	int age = s.nextInt();
               	
               	System.out.println("请输入工资：");
               	double salary = s.nextDouble();
               	
               	Employee tmp = new Worker(name,age,salary);
               	ema.add(tmp);
               }else if(op == 2){
               	ema.showAll();
               }else if(op == 3){
               	System.out.println("请输入要删除用户的姓名：");
               	String name = s.next();
               	ema.deleByName(name);
               }
   		}
   		s.close();
   		
   	}
   }
