Java Learning 3 Create student properties: study number, name, telephone fully implement the object collection of additions and deletions to search. (Console to do)

First create a student class which includes get,set and constructors

/**
*
*/
Package WORK2;

/**
* @author Administrator
*
*/
Public final class Student {
Private String ID;
private int tell;
private String name;
/**
* Initialize Data
*/
Public Student (String id,int tell,string name) {//constructor assigns an initial value
TODO Auto-generated constructor stub
This.id=id;
This.tell=tell;
This.name=name;
}

/**
*
* @param incoming data set and get method, data security, gave the method to pass in the data itself
*/

public void SetId (String id) {
This.id=id;
}
public void Settell (int tell) {
This.tell=tell;
}
public void SetName (String name) {
This.name=name;
}
Public String getId () {
return ID;
}
public int Geitell () {
return tell;
}
Public String Geiname () {
return name;
}
}

In creating a MyClass class including adding additions and deletions to the search method

Package WORK2;

Import java.util.ArrayList;
Import java.util.List;

public class MyClass {
Set up a list container to load data
Private list<student> stulist;

Public MyClass () {
Stulist=new arraylist<student> ();//Create a Stu Object
}

public boolean ishere (Student stu) {//encapsulation method for judging a number
Boolean is=false;
for (Student s:stulist) {//traverse for each
if (Stu.getid (). Equals (S.getid ()))//The object data passed in the container = traversed object data exists, otherwise does not exist
Is=true;
}
return is;//returns judgment
}

Public boolean Add (Student stu) {
First, determine if there is
Boolean is=this.ishere (Stu);
if (!is) {
Stulist.add (Stu);
}
return!is;
}

public boolean upDate (Student stu) {
First, determine if there is
Boolean is=this.ishere (Stu);
for (Student s:stulist) {
if (Stu.getid (). Equals (S.getid ())) {
Stulist.remove (s);
Stulist.add (Stu);
}
}
return is;
}

public Boolean delete (String ID) {
Boolean issuc=false;
for (Student s:stulist) {
if (Id.equals (S.getid ())) {
Stulist.remove (s);
Issuc=true;
}
}
return ISSUC;
}

Public list<student> query () {
return this.stulist;


}
}

Finally create a mainframe class using the Model View Controller

By calling the method in MyClass to implement the

Package WORK2;

Import java.util.List;
Import Java.util.Scanner;

Import Javax.swing.plaf.synth.SynthStyle;

public class MainFrame {
Public MyClass mc;//Object
Private Scanner sc=new Scanner (system.in);
Public MainFrame () {
TODO Auto-generated constructor stub
Mc=new MyClass ();
}
Public Student GetInfo () {//constructor with parameters
System.out.println ("Please enter the study number");
String Id=sc.next ();
System.out.println ("Please enter the telephone");
int Tell=sc.nextint ();
System.out.println ("Please enter name");
String Name=sc.next ();
Student stu=new Student (ID, tell, name);//data encapsulated into objects,
return Stu;

}
public void Add () {
Student stu=this.getinfo ();//Receive data from the console
Boolean Is=mc.add (Stu);
if (IS) {
System.err.println ("add success");

}
Else
System.out.println ("Add failed");
}

public void Update () {
Student Stu=this.getinfo ();
Boolean is=mc.update (Stu);
if (IS) {
SYSTEM.OUT.PRINTLN ("Modification/success");
}else
SYSTEM.OUT.PRINTLN ("modification failed");
}
public void Delete () {
System.out.println ("Please enter the student's number to delete");
String Id=sc.next ();
Boolean is=mc.delete (ID);
if (IS) {
System.out.println ("delete succeeded");
}else
System.out.println ("Delete failed, student does not exist");

}

public void Quere () {
List<student> Stulist=mc.query ();
for (Student s:stulist) {
System.out.println ("ID:" +s.getid () + "Tell:" +s.geitell () + "Name:" +s.geiname ());

}
}

public void Start () {
Boolean is=true;
while (IS) {
System.out.println ("Enter the option you want to operate:");
System.out.println ("1, increase");
System.out.println ("2. Delete");
System.out.println ("3, modify");
System.out.println ("4, find");
System.out.println ("5, exit");
int Option=sc.nextint ();
Switch (option) {
Case 1:
System.out.println ("Start adding");
Add ();
Break

Case 2:
SYSTEM.OUT.PRINTLN ("Start modification");
Update ();
Break
Case 3:
System.out.println ("Start query");
Quere ();
Break
Case 4:
System.out.println ("start delete");
Delete ();
Break
Case 5:
Is=false;
System.out.println ("Welcome to use, see you next time!! ");
}
}

}
public static void Main (string[] args) {
MainFrame mf=new MainFrame ();
Mf.start ();
}

}
