For label you need to create and initialize the JLabel class object and add it to container. Inorder to do that you need to import javax.swing.*
So the code must contain the following lines to add label and text field
JLabel l1=new JLabel("Enter name");
JTextField tf1=new JTextField(10);
con.add(l1);
con.add(tf1);

I am very new to Java, I followed your instruction and this is what I came up with, am I missing something?
print("{
JFrame f = new JFrame();
JLabel l1 = new JLabel();
JTextField tf1 = new JTextField ();
SchoolOption f1 = new SchoolOption();
Color c = new Color(128,0,0);
Container con = f.getContentPane();
con.setBackground(c);
con.add(l1);
con.add(tf1);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setSize(400, 120);
f.setTitle("Bloomfield College Student Registration System");
f.setResizable(false);
f.setLocationRelativeTo(null);
f.setVisible(true);
l1.setVisible(true);
//tf1.setVisible(true)
}");
