    Default Painfully simple Applet problem.

    Hey all, I'm trying to learn how to build applets, and I simply can't get my browser to run one! Originally I was using Chrome, but I switched to Firefox and got the same error.

    Here's the applet trying to load: ImageShack® - Online Photo and Video Hosting

    I "click for details" and this window comes up: ImageShack® - Online Photo and Video Hosting

    I click "details" and this comes up: ImageShack® - Online Photo and Video Hosting

    Unfortunately, I have no idea what the problem means....

    Here's my applet code and my html code:
    import java.applet.*;
    import java.awt.*;
     
    class MyApplet extends Applet {
     
    	Font bigFont;
    	Color whiteColor;
     
    	public void init() {
    		bigFont = new Font("Arial", Font.BOLD, 16);
    		whiteColor = Color.white;
    		setBackground(whiteColor);
    	}
     
    	public void paint(Graphics g) {
    		g.setFont(bigFont);
    		g.drawString("Austin Rose", 80, 20);
    	}
     
    	public void stop() {
     
    	}
    }

    <HTML>
     
    <HEAD> 
    <TITLE> Austin's Applet </TITLE>
    </HEAD>
     
    <BODY>
    <applet code="MyApplet.class" width="300" height="300">
    </BODY>
     
    </HTML>

    Any help is greatly appreciated!

    I think it is saying that your class has to be public

    The error description says that it can not access the modifiers "" of MyApplet class. Well, i am not sure what exactly the problem is but try to comment
    bigFont = new Font("Arial", Font.BOLD, 16);
    this line and in paint() method draw something else and see.

    The problem is in your paint method. Try this instead.

        public void paint (Graphics g) {
     
            //Cast the Graphics object into a Graphics2D object
            Graphics g2 = (Graphics2D) g;
     
            // Draw the string
            g2.drawString("Hello", 10, 10);
     
            //Finished painting
            g2.finalize();
        }

    And here is a full template that works for me if you have any more problems.

    import java.applet.Applet;
    import java.awt.*;
     
    public class MyApplet extends Applet {
     
        public void init() {} 
     
        public void stop() {} 
     
        public void destroy() {} 
     
        public void paint (Graphics g) {
     
            //Cast the Graphics object into a Graphics2D
            Graphics g2 = (Graphics2D) g;
     
            // Draw the string
            g2.drawString("Hello", 10, 10);
     
            //Finished painting
            g2.finalize();
        }
     
        public void run () {
              repaint();
        }
     
    }
