Applet is missing conditions

I am trying to create an airline reservation system applet  for a single airplane airline that seats 10.  As shown in my code below, the plane has seats 1-5 designated as smoking and 6-10 as non-smoking.  My problem is I can't figure out where or how to add a method(?) that would ask a person if he/she wants to move to another section if the section (i.e. , smoking) he/she wants to seat in is full.  The passenger needs to be able to choose between two options, one is YES which would assign him/her a seat in the other section and would print out his/her "boarding pass" and NO which would then output a message "Next flight leaves in 3 hours."  

//Airline.java
  import java.awt.*;
  import java.applet.Applet;

  public class Airline extends Applet {
     int seats[];
     int type;
     String smoker, nsmoker;
     Label prompt1;
     TextField input1;
     Label prompt2;
     TextField input2;
     Button button1, button2;

     public void init()
     {
        seats = new int [10];
       
        for (int i = 0; i <= 10; i++ );
        seats[i] = i

        prompt1 = new Label ( "Please enter seat type" );
        input1 = new TextField (5);
        prompt2 = new Label ( "Your seating info:" );
        input2 = new TextField (25);
        button1 = new Button( "Yes" );
        button2 = new Button( "No" );
        add(prompt1);
        add(input1);
        add(prompt2);
        add(input2);
        add(button1);
        add(button2);
     }
     
     public void paint( Graphics g )
     {  
        g.drawString( "Welcome to Alpha Airlines", 40, 105 );
        g.drawString( "Airline Reservation System", 40, 120 );
        g.drawString( "Please type 1 for smoking", 40, 145 );
        g.drawString( "Please type 2 for nonsmoking", 40, 160 );
     }
     
     public boolean action( Event e, Object o)
     {
        if ( e.target == input1 ) {
           type = Integer.parseInt(input1.getText() );
       
               if ( type == 1 )
                  input2.setText( "seat #" + nsmoker + "- non-smoking" );
                  nsmoker = findSeat1(Integer.parseInt (type) );    
               else if ( type == 2 )
                  input2.setText( "seat #" + smoker + "- smoking" );
                  smoker = findSeat2(Integer.parseInt (type) );
        }
        return true;
     }            
     
     public int findSeat1( int x )
     {
         for ( int x = 1; x <=5; x++ )
             if ( seats[x] <= 5 )
                return x;
             else
                input2.setText( "All non-smoking seats taken.  Move to smoking?");            
     }

     public int findSeat2( int y )
     {
         for ( int y = 6; y <=10; y++ )
             if ( seats[y] <= 10 )
                return y;
             else
                input2.setText( "All smoking seats taken.  Move to non-smoking?");    
     }      
  }

I would probably just write some sort of Dialog into your code to get a boolean response. This is just a simple example but you'll need to write some extra code to handle the events. There's a good example of this yes/no type Dialog in David Flanagan's "Java in a Nutshell" book from O'Reilly. Basically if the user clicks "YES" you return true and if they click "NO" you return false.


public int findSeat1( int x ) {
  for ( int x = 1; x <=5; x++ ) {
    if ( seats[x] <= 5 ) return x;
  }
  else {
    input2.setText( "All non-smoking seats taken.");
    if (askDialog("Do you want a smoking seat")==true) {
      findSeat2();
    }
  }
}

public boolean askDialog(String str){
  Dialog d=new Dialog();
  d.setLayout(new BorderLayout());
  d.add("Center",new Label(str);
  Button yes=new Button("YES");
  Button no=new Button("NO");
  Panel p=new Panel();
  p.add("West"),no);
  p.add("East",yes);
  d.add("South",p);
  d.pack();
  d.show();
}
