Hi i have created a private class "PathakP" but i am getting PathakP cannot be resolved to a type : Ok i tried to create a dialog box with Jbutton but when i am adding actionListener to it and passing the class to button which i have created to implements ActionListener i am getting "PathakP(Class Name) cannot be resolved to a type"

the code i have used is 

       import java.awt.*;

       import javax.swing.*;

       import java.awt.event.*;

       public class GUI1 extends JFrame {

	   private JTextField J;
	   private Font pf,bf,itf,bif;
	   private JRadioButton pb,bb,ib,bib;
	   private ButtonGroup B;
	   private JButton ab;
	
	    public  GUI1(){
		super("To check the Font styles" );
		setLayout(new FlowLayout());
		
		 J=new JTextField("This is the Text who's Font will be Changed pahtak is           with me ",40);
		add(J);
		pb=new JRadioButton("Plain Button",true);
		bb=new JRadioButton("Bold Button",false);
		bib=new JRadioButton("Bold & Italic Button",false);
		ib=new JRadioButton("Italic Button",false);
		ab=new JButton("PathakButton");
		add(ab);
				
		add(pb);
		add(bb);
		add(bib);
		add(ib);
		
		B=new ButtonGroup();
		B.add(pb);
		B.add(bb);
		B.add(bib);
		B.add(ib);
		
		pf=new Font("Serif",Font.PLAIN,15);
		bf=new Font("Serif",Font.BOLD,15);
		itf=new Font("Serif",Font.ITALIC,15);
		bif=new Font("Serif",Font.BOLD+Font.ITALIC,16);
		J.setFont(pf);		
		
		
		pb.addItemListener(new HandlerClass(pf));
		bb.addItemListener(new HandlerClass(bf));
		bib.addItemListener(new HandlerClass(bif));
		ib.addItemListener(new HandlerClass(itf));
		
		ab.addActionListener(new PathakP());
	}
        private class HandlerClass implements  ItemListener{
      private Font font;
	  public HandlerClass(Font f){
		font=f;
	}
	
	  public void itemStateChanged(ItemEvent e) {
		// TODO Auto-generated method stub
		J.setFont(font);
	}
	
	     private class PathakP implements ActionListener{

	
		public void actionPerformed(ActionEvent ae) {
			
			JOptionPane.showMessageDialog(null, "This is just JOptionPane example");
		}
		
	}
	
	
}
	
}

Main Class

import javax.swing.*;
public class Apples {

	public static void main(String[] args) {
		GUI1 G=new GUI1();
		G.setVisible(true);
		G.setSize(500,250);
		G.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

	}

}
-----------------
i don't believe there is any error in the main class
i can troubleshoot this error by just creating another class outside but i want to know why it is not taking the class i have created and show unused in it
