//creating container
      Container c=this.getContentPane();
c.setLayout(null);

                //creating textfield and set their layout
t1=new JTextField();
t1.setBounds(200,100,130,20);

                 //creating label and set their layout
l1= new JLabel("what is your name");
l1.setBounds(50,100,250,30);
