      JFrame frame = new JFrame();
      Container container;
      JButton btn;
      frame.setBounds(20, 20, 15, 15);
      container = frame.getContentPane();
      container.setLayout(new FlowLayout());
      btn = new JButton("Submit");
      JCheckBox checkBox1 = new JCheckBox("Graduate");
      JCheckBox checkBox2 = new JCheckBox("Post-Graduate");
      container.add(btn);
      container.add(checkBox1);
      container.add(checkBox2);
