This article mainly introduces the relevant knowledge of java how to achieve the student dormitory system, the content is detailed and easy to understand, the operation is simple and fast, and has a certain reference value. I believe you will gain something after reading this java article on how to achieve the student dormitory system. Let's take a look at it.

Student class code

Student.java

Package dormitory;public class Student {private String id; private String name; private String sex; private String dormid; public String getId () {return id;} public void setId (String id) {this.id = id;} public String getName () {return name;} public void setName (String name) {this.name = name } public String getSex () {return sex;} public void setSex (String sex) {this.sex = sex;} public String getDormid () {return dormid;} public void setDormid (String dormid) {this.dormid = dormid;}}

Main operation code

IntailStudent.java

Package dormitory;import java.awt.List;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.FileNotFoundException;import java.io.FileReader;import java.io.FileWriter;import java.io.IOException;import java.util.ArrayList;import java.util.Iterator;import java.util.Scanner;import javax.print.DocFlavor.INPUT_STREAM;import javax.swing.event.ListSelectionEvent;import org.omg.PortableInterceptor.IORInterceptor;public class InitailStudent {private static int naughty; private static Student [] stu=new Student [100] / / main function public static void main (String [] args) throws IOException {boolean a false; boolean bounded false; InitailStudent student=new InitailStudent (); student.judge (a, b);} / login function private void judge (boolean a, boolean b) throws IOException {do {System.out.println ("Welcome to the login page!") ; Scanner input=new Scanner (System.in); System.out.println ("Please enter account:"); String account=input.nextLine (); System.out.println ("Please enter password:"); String code=input.nextLine (); a=account.equals ("admin"); b=code.equals ("admin");} while (! (a==true&&b==true)) Menu ();} / / system menu page private void Menu () throws IOException {Scanner input=new Scanner (System.in); System.out.println ("- Welcome to the dormitory management system -"); System.out.println ("- Please select the following actions -") System.out.println ("--1.
