Question

I have 2 class files called PaintMe.java and Starter.java.
PaintMe.java contains:

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

public class PaintMe extends Applet {
    public void paint(Graphics g) {
        g.setColor(Color.red);
        g.drawString("HELLOOO", 15, 25);
    }
}

Starter.java contains:

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


public class Starter {
    public static void main(String[] args) {
        PaintMe ring = new PaintMe();
        ring.paint();
    }
}

So question is, how can I paint my string with calling a paint method from Starter.java?

Answer 1

To get it to compile, change

ring.paint();

..to..

ring.repaint();

Notes

1. Don’t code using AWT in this millennium. Use Swing (which offers a JApplet).
2. Don’t start an applet from the main(String[]). An applet is started by the JRE when it is embedded in a web page (or launched using JWS). A GUI can be designed in a panel, that is then put in a free-floating application or applet. That is known as a hybrid. But both frame and applet separately add the GUI, which is (most often) a different class to either.
3. The main as it exists is useless. Unless the applet is added to a container and made visible, the code will run successfully but end in a few moments without displaying anything.

Update 1

..tried that, but it still doesn’t draw my string in the applet window.

Try this.

Source

// <applet code='PaintMe' width=300 height=50></applet>
import java.applet.Applet;
import java.awt.*;

public class PaintMe extends Applet {
    public void paint(Graphics g) {
        g.setColor(Color.red);
        g.drawString("HELLOOO", 15, 25);
    }
}

Prompt

> javac PaintMe.java
> appletviewer PaintMe.java

Update 2

..I need to have it started from Starter.java class.

I think that is a silly requirement, and it seems like JWS (as mentioned & linked in comments) launching a JFrame is the best way to view this GUI. OTOH, here is a (very) naive implementation of the Starter class that will show that applet on-screen.

It mixes AWT and Swing (bad), it does not attempt to implement any sort of applet context, and does not call the applet init/start/stop/destroy methods, but is enough to get the applet on-screen from another class.

import java.awt.Dimension;
import javax.swing.JOptionPane;

public class Starter {
    public static void main(String[] args) {
        PaintMe ring = new PaintMe();
        ring.setPreferredSize(new Dimension(250,30));
        JOptionPane.showMessageDialog(null, ring);
    }
}
