Problem with methods to do graphics.

[Brian Walsh]

Hi again...
Sorry to bug you guys about the same old program but I am having having problems getting to the methods of Guest.java to do graphic commands. It all comppiled fine but when Diner.java implements
"placeCheck();" & "colorCheck(page);" it does'nt show up in the applet when I run it.
Here is:
Guest.java
Diner.java

THANK YOU SOOOOO MUCH FOR YOUR HELP!!!

 import java.applet.Applet;
import java.awt.*;
public class Guest extends Object
{
   private int place;
   private int  gender ;
   private String owner;
   private int placeX;
   private int placeY;
   private int width = 50;
   private int x = 54, y = 73;
   private int tableWidth = 79, tableHeight = 140;
   //-----------------------------------------------------------------
   //  Sets up the account by defining its owner, account number,
   //  and initial balance.
   //-----------------------------------------------------------------
   public Guest (String owner, int gender, double place)
   {
   }

   public int colorCheck (Graphics page)//draws circle according to sex
   {
         switch (gender)
         {
 case 1: //male
 {
 page.setColor (Color.blue);
     page.fillOval (placeX, placeY, width, width);
 page.setColor (Color.black);
 page.drawString (owner, placeX, placeY);
 break;
     }
case 2://female
{
page.setColor (Color.pink);
    page.fillOval (placeX, placeY, width, width);
    page.setColor (Color.black);
    page.drawString ( owner, placeX, placeY);
    break;
    }
          }
           return gender;
   }

   public int placeCheck ()//draws spot according to variable "place."
      {
            switch (place)
            {
   case 1: //place 1
    {
   placeX = 39;
   placeY = 90;
   break;
        }
   case 2://place 2
   {
   placeX = 39;
   placeY = 140;
   break;
       }
       case 3: //place 3
    {
   placeX = 148;
   placeY = 90;
   break;
       }
       case 4: //place 4
    {
placeX = 148;
placeY = 140;
break;
       }
             }
               return gender;
        }

} 

 import java.applet.Applet;
import java.awt.*;
import Guest;

public class Diner extends Applet
{
   //-----------------------------------------------------------------
   //  Creates guests at party!!!
   //-----------------------------------------------------------------
   public void paint (Graphics page)
   {
      Guest webly= new Guest ("Webly", 2, 1);
      Guest brian = new Guest ("Brian", 1, 2);
      Guest mom = new Guest ("Mom", 2, 3);
   //-----------------------------------------------------------------
   //  Makes a Table
   //-----------------------------------------------------------------
      page.setColor (Color.black);
  page.drawRect ( 54, 73, 79,140 );
   //-----------------------------------------------------------------
   //  Calls methods for showing guests
   //-----------------------------------------------------------------
      webly.placeCheck();
      webly.colorCheck(page);
      brian.placeCheck();
      brian.colorCheck(page);
      mom.placeCheck();
      mom.colorCheck(page);

Moving this to applets

Hi Brian,
You are missing the part about transferring the constructor parameters to the class variables. You are not doing that; therefore you are only dealing with default class values. Do this for your Guest constructor and things should work out.

  
  public Guest (String owner, int gender, int place)   
  {   
    this.owner = owner;
    this.gender = gender;
    this.place = place;
  }

For some reason your constructor was accepting double for place and your class was defining it as integer. I went with integer.
The drawing was close but not quite right. Good start though!
Regards,
Manfred.
