CHAPTER 61 — GUI Applications

The example program in the previous chapter (which repeats what the user enters) is not very useful. This chapter develops two applications that are just on the fringe of being useful. Along the way, it discusses several additional topics in Swing programming.

Chapter Topics:

• Example: Temperature conversion application.
• Obtaining numeric values from JTextFields.
• Writing results into JTextFields.
• ActionListener for a JTextField.
• Example: Calories from fat calculation.
• Using a JButton with JTextField input.
• Finding the right size for a frame.
