Airline Reservation System

Question

An Airline wants to design a reservation system based on the following conditions:
�h Each Plane has capacity of 10 seats.
�h Applet should display the following options at the top of applet window
��Please type 1 for ��Non-Smoking��
��Please type 2 for ��Smoking��
Note: Types 1 and 2 are inputs and this will be accepted through a text field, if person types any wrong option type (other than 1 or 2), display a message at the status bar (last bottom line of window) that ��Invalid Input��.
�h If a person types 1, program should assign a seat in the Non-Smoking section (seats 1 to 5) of the plane
�h If a person types 2, program should assign a seat in the Smoking section (seats 6 to 10) of the plane
�h Use a single dimensional array to represent the seating chart of the plane and initialize all the elements of array to 0 (zero) which indicates that all the seats are available.
�h As each seat is assigned, set the corresponding element of array to 1 which indicates that this seat is no longer available.
Note: After proper seat assignment, display message at the bottom line of window (status bar) , for example : ��Smoking Seat # 6�� OR ��Non-Smoking Seat # 2�� etc�K
�h Program should never assign a seat that has already been assigned.
�h When the Smoking section of Plane is full, Program should ask the person if it is acceptable to be placed in the non-smoking section and (vice versa as well)
Note: Display message �� Smoking is full, Non-Smoking ?��
          �� Non-Smoking is full, Smoking ?��
If answer to any of the above question is yes, make appropriate seat
assignment in the program.
If answer to any of the above question is No, display the message at the
status bar of Applet window (very bottom of window) that ��Next Fight leaves
in 3 hours��
Some important points to consider
1: As this is an applet program, it will have a full Graphical and Event handling capability.
2: Your important GUI components (use all Swing classes for GUI) in this applet program are:
a text field for input ( 1 or 2)
two Labels to indicate the options to user (see above 2nd bullet)
two buttons which will be pressed in response to the questions as mentioned
above in bullet no. 8
Note: Please note that when your applet will start, initially these buttons will not function (make these buttons as disabled). Make them active (enabled) when either section of plane (Smoking or non-smoking) is full and you generate a message as stated above in last bullet 8.
3: When applet will start, both buttons will be disabled and only activity on applet window will be through the input field (where user can either input 1 or 2)
4: Please note that input text field can also be registered for action event listener as you normally do for buttons, for example.
Therefore, when you will type 1 or 2 in the input field and press <ENTER> key, based on the event handling process, proper seat will be assigned and message will be displayed on the status bar as mentioned above in bullet No. 6.
5: Every message will always be displayed in the status bar of applet window (very bottom line of the window)
6: In your HTML file, use Width and Height parameters both 200 pixels.

Answer 1

How is this for a start
import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Reserv extends JApplet implements ActionListener
     JTextField type   = new JTextField(1);
     JTextField status = new JTextField("");
     int        sits[] = new int[10];
     JLabel     lab1   = new JLabel("Please type 1 for Non-Smoking");
     JLabel     lab2   = new JLabel("Please type 2 for Smoking");
public void init()
     getContentPane().setLayout(null);
     lab1.setBounds(5,10,190,21);
     lab2.setBounds(5,30,190,21);
     type.setBounds(200,30,20,21);
     type.addActionListener(this);
     getContentPane().add(lab1);
     getContentPane().add(lab2);
     getContentPane().add(type);
     status.setBounds(1,180,350,21);
     status.setBackground(Color.red);
     status.setForeground(Color.white);
     getContentPane().add(status);
     status.setEditable(false);
public void actionPerformed(ActionEvent ae)
     status.setText("");
     if (type.getText().equals("1"))
//          findNoSmoke();
          return;
     if (type.getText().equals("2"))
//          findSmoke();
          return;
     status.setText("Invalid Input");
