java applet help

  Asked By: Muaz    Date: Feb 17    Category: Java    Views: 1012
  

am doing a simple hotel boooking system shown below. i am having
trouble writing 2 of my methods. the listrooms method and the
addclient method, can anyone help. the add client method should read
the text field and store the name in the specified location of a
array which i have set up, but if that certain location of a array
is boked then then it should give an error message. if a rom number
outside the range of the array is entered it should also give a
error message. the other method( list rooms) should display each
client and room they occupy and display them into the text fields
each time the list button is pressed
i have'nt got a clue where to start with writing them. any tips or
help would be wounderful

import java.applet.Applet;
import java.awt.*;
import java.awt.event.*;
public class Hotel1 extends Applet implements ActionListener
{


static String names[] = new String[10 ;

TextField nameofoccupant = new TextField ("name of occupant", 25);
TextField roomnum = new TextField ("room number", 5);

Button b1 = new Button ("reset");
Button b2 = new Button ("list rooms");
Button b3 = new Button ("add client");
Button b4 = new Button ("search by name");
Button b5 = new Button ("search by room number");



public void init()
{
setSize(600,400);
setBackground(Color.white);

add(b1);
add(b2);
add(b3);
add(b4);
add(b5);

add(nameofoccupant);
add(roomnum);
nameofoccupant.addActionListener(this);
roomnum.addActionListener(this);
}


public void paint ( Graphics g)
{
g.drawString("______________________",200,280);
g.drawString("MY HOTEL LIMITED",200,300);
g.drawString("______________________",200,320);
g.drawString("number of rooms---- 15", 100,150);
g.drawString("number of avaliable rooms----", 100,190);



}





public void listrooms()
{


}


public void addclient()
{


}


public void actionPerformed(java.awt.event.ActionEvent actionEvent) {
}

public void mouseClicked(java.awt.event.MouseEvent mouseEvent) {
}

public void mouseEntered(java.awt.event.MouseEvent mouseEvent) {
}

public void mouseExited(java.awt.event.MouseEvent mouseEvent) {
}

public void mousePressed(java.awt.event.MouseEvent mouseEvent) {
}

You did not use the file,filereader method
without this you cannot write the programme
you can write with this help  in the search  method
use try and catch(Exception name) //outofArraybound
message.
