    Default To Create and Admin an database

    Hi

    Assignement:

    Im trying to create an database that contains personal information to several clients using an java program. But im stuck and i need help.

    I have created two classes: Database and Client

    - My problems is as followed:

    1 - Creating a method "AddUser", which can register a new "client" to the database.

    2- Creating a method "RemoveUser" which makes it possible to delete a excisting client from the database.

    3- Creating a method"showClientList", which will with the help of System.out.println( ) method, print out a list in the following format:

    Client number______ Name
    --------------------------------------
    00001____________Thomas
    00002____________ Jeff

    It very important that you only print out people that allready excists in the database. and not for the "empty spaces"

    4 - Create a method "printOutOldest", which will print out the oldest client, by the age.


    This is the foundation for the program:

    Class: Client.


    public class Client
    {
    private String name;
    private int clientNumber;
    private int age;

    public Client(String name, int clientNumber, int age)
    {
    this.name = name;
    this.clientNumber = clientnumber;
    this.age = age;
    }

    }


    Class: Database

    import.java.util.Scanner;

    public class Database
    {
    private Scanner input;
    private Client [ ] users;

    public Database( )
    {
    input = newScanner(system.in);
    users = newClient [20]

    }


    public void addUser( )
    {
    }

    public void removeUser( )
    {

    }

    public void showClientList
    {

    }

    public public void printOutOldest( )
    {

    }

    }
