Java实现员工信息管理系统

Java实现员⼯信息管理系统在Java SE中，对IO流与集合的操作在应⽤中⽐较重要。

接下来，我以⼀个⼩型项⽬的形式，演⽰IO流、集合等知识点在实践中的运⽤。

该项⽬名称为“员⼯信息管理系统”（或“员⼯收录系统”），主要是通过输⼊员⼯的id、姓名信息，实现简单的增删改查功能。

该项⽬主要在DOS窗⼝的控制台或者Eclipse的控制台上进⾏操作。

操作界⾯如下：该项⽬的⽂件结构如下：Step 1：⼊⼝类SystemMain的代码为：package empsystem;import java.util.Scanner;/*** 主界⾯* ⼀个Scanner录⼊对象* Employ类* ⽂件路径* 查重SearchID* @author 李章勇**/public class SystemMain {private Scanner sc=new Scanner(System.in);public SystemMain() {showWelcome();}public void showWelcome(){System.out.println("----员⼯收录系统");System.out.println("1.增加员⼯功能");System.out.println("2.查看员⼯功能");System.out.println("3.修改员⼯功能");System.out.println("4.删除员⼯功能");System.out.println("5.退出系统");String choice=sc.nextLine();switch(choice){case "1":System.out.println("您选择了增加⽤户功能");//Addnew Add();break;case "2":System.out.println("您选择了查看⽤户功能");//Searchnew ShowEmp();break;case "3":System.out.println("您选择了修改⽤户功能");//Modifynew Modify();break;case "4":System.out.println("您选择了删除⽤户功能");//删除⽤户Deletenew Delete();break;case "5":System.out.println("您选择了退出系统");return;default:System.out.println("⽆此功能");break;}}}Step 2：写⽂件路径FilePath接⼝。
