public void actionPerformed(ActionEvent e)
     //String x=txt1.getText();
     //String y=txt2.getText();
     String s ="(Select XPosition from data where parameter=ST01)";
     String s1 ="(Select YPosition from data where parameter=ST01)";
     int i = Integer.parseInt(s);
     int j = Integer.parseInt(s1);
     String str = e.getActionCommand();
     if(str.equals("btn1"))
          cr = new Circle();
          cr.setSize(30,30);
          cr.setLocation(i,j); // here its problem
          p2.add(cr);
          show();
