Using list in Java to implement a simple student management system

As a Java programmer, regardless of beginner or great God, student management system is a good example, beginners with arrays, lists and so on to write a simple student management system, the great God is to use the swing+ database to do the interface of the student management system, nonsense not much to say, Today, I use list to implement the student management system.

Student management system mainly for students, we first write the student object.

Package Testproject;public class Student {    String name;    String age;    Public String GetName () {        return name;    }    public void SetName (String name) {        this.name = name;    }    Public String Getage () {        return age;    }    public void Setage (String age) {        this.age = age;    }}

Here are some * get and set methods (more lazy to write two casually)

    System.out.println ("Welcome to Student management System");    System.out.println ("" 1 "registration");    System.out.println ("" 2 "View");    System.out.println ("3" and "Modified");    System.out.println ("" 4 "delete");    System.out.print ("Please select your action:");

The following is the main page of the implementation of the various functions crap, don't say much about code.

Package Testproject;import Java.util.arraylist;import Java.util.list;import Java.util.scanner;public class    Testdemo02 {/** * operator interface */static Scanner SCA = new Scanner (system.in);    static list<student> L = new arraylist<student> ();    static student C = new student ();    Static Boolean Stu = true;        public static void Main (string[] args) {System.out.println ("Welcome to Student management System");        System.out.println ("" 1 "registration");        System.out.println ("" 2 "View");        System.out.println ("3" and "Modified");        System.out.println ("" 4 "delete");        System.out.print ("Please select your action:");            while (Stu) {String stus = Sca.nextline ();                Switch (stus) {case "1": Add ();            Break                Case "2": sel ();            Break                Case "3": Set ();            Break                Case "4": Del ();            Break }}}/*** * Add function */Static void Add () {while (Stu) {System.out.println ("Please enter student name");            C.setname (Sca.nextline ());            System.out.println ("Please enter student age");            C.setage (Sca.nextline ());            System.out.println ("add success");            L.add (c);        Break }}/** * Query function * * * static void Sel () {for (student c:l) {System.out.println ("Name:" +c.        GetName () + "" + "Age:" +c.getage ());        }}/** * Delete function */static void Del () {System.out.println ("Please enter name to delete");        String names = Sca.nextline (); for (int i=0;i<l.size (); i++) {if (Names.equals (L.get (i). GetName ())) {System.out.println ("Find student                deleting ");                L.remove (i);            System.out.println ("delete succeeded");            }else {System.out.println ("deletion failed to find student");        }}}/** * Modify function */static void set () {System.out.println ("Please enter the name of the student to be modified"); String names = Sca.nextline(); for (int i=0;i<l.size (); i++) {if (Names.equals (L.get (i). GetName ())) {System.out.println ("Discover student                Being modified ");                System.out.println ("Please enter the modified name");                String name = Sca.nextline ();                L.get (i). SetName (name);                System.out.println ("Please enter the Modified age");                String age = Sca.nextline ();                L.get (i). Setage (age);            SYSTEM.OUT.PRINTLN ("modified successfully");            }else{System.out.println ("Student not Found" in the "Modification failed"); }        }    }}

Is it very easy to see these? Beginners are a good fit to get practiced hand.
A simple student management system is complete is not very simple?
