Thread: 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( )
{

}

}

Have you even started this yet? No one is going to complete your assignment for you.
Please post as much code as you can and tell us where you are stuck.. We can take it from there.

public void addUser()
{
int age;
int clientNumber;


System.out.println("Input name: ");
String name = input.next();
System.out.println("Input clientnumber: ");
clientNumber = input.nextInt();
System.out.println("Input age: ");
age = input.nextInt();

new Client(name, clientNumber, age);
}
