This is what I modified ur program and executed....
import java.util.ArrayList;
import java.util.Iterator;
import java.awt.*;
import javax.swing.*;
class Complete extends JPanel
JFrame jf1;
Graphics gg;
String name;
ArrayList attributes;     
ArrayList operations;
Point p;
Iterator itr;
/*Complete(ArrayList attr,ArrayList oper,String nm)     {
     jf1 = new JFrame();     
     JButton hi = new JButton("Hi");
     this.setBackground(Color.WHITE);
     this.setLayout(new BorderLayout());
     this.setBorder(BorderFactory.createLineBorder (Color.blue, 2));      
     this.add(hi);
     jf1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
     jf1.setVisible(true);
     jf1.add(this);
     attributes=attr;
     operations=oper;
     name=nm;     
     public Complete() {
          // TODO Auto-generated constructor stub
     public void paintComponent(Graphics g)     {
     super.paintComponent(g);
gg = (Graphics2D)g;
     p=this.getLocationOnScreen();     
     p.x=p.x+30;
     System.out.println("inside this");
     public static void main(String[] args){
          Complete cmp = new Complete();     
          cmp.Call();
     void Call(){
          attributes = new ArrayList();
          operations = new ArrayList();
          attributes.add(new Integer(1));
          attributes.add(new Integer(2));
          attributes.add(new Integer(3));
          operations.add(new String("Hi"));
          operations.add(new String("Bye"));
          operations.add(new String("Run"));
          Complete(attributes, operations, "Intoto");
     private void Complete(ArrayList attr,ArrayList oper,String nm) {
          jf1 = new JFrame();     
          this.setBackground(Color.WHITE);
          this.setBorder(BorderFactory.createLineBorder (Color.blue, 2));      
          JButton hi = new JButton("Hi");
          this.setBackground(Color.WHITE);
          this.setLayout(new BorderLayout());
          this.setBorder(BorderFactory.createLineBorder (Color.blue, 2));      
          this.add(hi);
          jf1.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          jf1.setVisible(true);
          jf1.add(this);
          jf1.setSize(50, 100);
          attributes=attr;
