Question

Why Am I getting an error. In eclipse it says constructor call should be the first line. It is the first line. or you can not extend Main?

import javax.swing.JFrame;
import javax.swing.JLabel;

    public class Main extends JFrame{

        /**
         * @param args
         */
        public static void main(String[] args) {
            // TODO Auto-generated method stub
            //JLabel testLabel1 = new JLabel();
            public Main(){
                super("title bar");
            }
        }

    }

Answer 1

Your Main constructor should sit outside of the main method. Like so:

public class Main extends JFrame {
    public Main() {
        super("title bar");
    }

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        //JLabel testLabel1 = new JLabel();
    }
}
