Hello I just began learning java just a couple days ago, [it is basicly my first language] I seem to have a problem with this tutorial on applets (my applet is broken :tear: ) http://www.mandomartis.com/onlinecourses/basicgamedev/chapter2/chapter2.html

 

It tells me to compile this to a class....

import java.applet.*;

import java.awt.*;



public class myapplet extends Applet {





public void init()

{

   System.out.println("Hello Sweden!");

}



}

 

 

and make an html of this and then open the html

 

<HTML>

<HEAD><TITLE>My first applet</TITLE></HEAD>

<BODY>

<APPLET CODE="myapplet.class" WIDTH=100 HEIGHT=100>

</APPLET>

</BODY>

</HTML>

 

It appears I am getting an error because I do not have a main class but I am not shure, I am doing exactly as the tutorial says is there something I should add. And if it is the main class how and where should I add it.

 

All help is greatly appreciated,

 

Regards, iMi

public static void main (String args[]) // <-- thats how you make a main

{

// code here

}

 

edit: Or thats how you do it w/ most Java, may be different for an applet

    import java.applet.Applet;

public class myapplet extends Applet {

   public void init() {
       System.out.println("Hello Sweden!");
   }

}

     

    In an applet, System.out.println() prints to the java console, obviously this is not what you want.

     

    In this case we need to draw a string, a picture of a penis, etc, when paint() is called....

     

    import java.applet.Applet;
import java.awt.Graphics;

public class myapplet extends Applet {

   public void init() {
   }

   public void paint(Graphics g) {
       g.drawString("Hello Sweden!", 20, 20);
   }

}

     

    Now the code in paint() will draw the string "Hello Sweden!" at x:20 and y:20, however, this still not work. You need to set the size of the applet.

     

    import java.applet.Applet;
import java.awt.Graphics;

public class myapplet extends Applet {

   public void init() {
       setSize(250, 250);
   }

   public void paint(Graphics g) {
       g.drawString("Hello Sweden!", 20, 20);
   }

}

     

    Now it has the ability to draw the string somewhere.
