Applet can't be instantiated

I am using a applet to create a GUI but whenever I am running the code it is showing "Applet not initialized". Error: load: home_1.class can't be instantiated.

The error is

 java.lang.InstantiationException
        at sun.reflect.InstantiationExceptionConstructorAccessorImpl.
newInstance(Unknown Source)
        at java.lang.reflect.Constructor.newInstance(Unknown Source)
        at java.lang.Class.newInstance(Unknown Source)
        at sun.applet.AppletPanel.createApplet(Unknown Source)
        at sun.applet.AppletPanel.runLoader(Unknown Source)
        at sun.applet.AppletPanel.run(Unknown Source)
        at java.lang.Thread.run(Unknown Source)

The code is...

import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public abstract class home_1 extends Applet implements ItemListener 
{
    Checkbox EPL,LALIGA,BUNDESH;
    CheckboxGroup menu;
    String msg="";
    public void init()
    {
        menu = new CheckboxGroup();
        EPL = new Checkbox("English Premier League",menu,true);
        LALIGA = new Checkbox("La Liga",menu,false);
        add(EPL);
        add(LALIGA);
        EPL.addItemListener(this);
        LALIGA.addItemListener(this);
    }
    public void itemStateChanged(ItemEvent ie)
    {
        repaint();
    }
    public void paint(Graphics g)
    {
        msg = "Current Selection: ";
        msg+=menu.getSelectedCheckbox().getLabel();
        g.drawString(msg,6,6);
    }

}

public abstract class home_1 and you're surprised it doesn't work?

abstract classes can't be instantiated...

Also, you must call super.paint(g) as the first line of your paint method.
