[rithish]

the errors are
Exception in thread "main" java.lang.Error: Unresolved compilation problems:

The type new ActionListener(){} must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)
The type new ActionListener(){} must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)

[mKorbel]

at begining change classname from log to MyLog, to avdiods the conflict with reserved words for some Java Method Name

public void actionPerformed(ActionEvent e) {

create a new class which contains just one TopLayoutCOntainer (JFrame, JDialog...) in type to the main method and inside actionPerformed

MyLo ml = new MyLog
ml.setVisible(true);// not neccesary for JFrame if contructor contains that

[JamesCherrill]

Your compile error is because

"ActionListener(){} must implement the inherited abstract method ActionListener.actionPerformed(ActionEvent)"

and you implemented actionperformed(ActionEvent)

(Java is case-sensitive)

[rithish]

create a new class which contains just one TopLayoutCOntainer (JFrame, JDialog...) in type to the main method and inside actionPerformed

i dont understand what u said sir

[mKorbel]

are you check

public void actionperformed(ActionEvent ae){

vs

public void actionPerformed(ActionEvent e) {

[mKorbel]

this one I meant

import java.awt.*;
import javax.swing.*;
import java.awt.event.*;

public class MyLog extends JFrame {

    private static final long serialVersionUID = 1L;

    public MyLog() {
        MyGui mg = new MyGui();
    }

    private class MyGui {

        private final JFrame frm;
        private final JPanel panel;
        private final JButton b1;

        public MyGui() {
            b1 = new JButton("ok");
            b1.addActionListener(new ActionListener() {

                public void actionPerformed(ActionEvent ae) {
                    MyGui mg = new MyGui();
                }
            });
            b1.setPreferredSize(new Dimension(200, 45));
            panel = new JPanel(new BorderLayout());
            panel.add(b1, BorderLayout.SOUTH);
            frm = new JFrame("MyFrame");
            frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
            frm.setPreferredSize(new Dimension(400, 300));
            frm.add(panel, BorderLayout.CENTER);
            frm.pack();
            frm.setVisible(true);
        }
    }

    public static void main(String args[]) {

    }
}
