//2. Optional: What happens when the frame closes?
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

//3. Create components and put them in the frame.
JLabel welcomeLabel = new JLabel("Welcome to JAVA!!");

contentPane.add(promptLabel);

JLabel nameLabel = new JLabel("Your Name will go Here!");
contentPane.add(nameLabel);
