JTextField setText Code Explanation

When Save button is clicked,a JOptionPane.showInputDialog shows up requesting user to enter his/her name.

The name is saved as String name and using [field.setText(name);] we are able to set Text in the JTextField.

Other methods used in this program:

• [field.setEnabled(false);]-Prevents user from directly entering text.
• [add.setBounds(50,100,100,20);]-sets JButton position on JFrame.
• [add.addActionListener(new ActionListener())]-Adds ActionListener to the JButton
