19 Differences between Applets and GUI Applications Applets Derived from JApplet No main method Uses init method Displayed by HTML Sets title in HTML Size set in HTML Applet closes when HTML doc closes GUI applications Class extends JFrame Invokes main method Uses constructors Uses method setvisible Uses settitle method Uses method setsize Closes with Exit button Java Programming: From Problem Analysis to Program Design, 5e 37 Converting a GUI Application to an Applet Change JFrame to JApplet Change constructor to method init Remove method calls such as setvisible, settitle, setsize Remove the method main If applicable, remove Exit button/all code associated with it (e.g., action listener) Java Programming: From Problem Analysis to Program Design, 5e 38 19
20 Additional GUI Components JTextArea JCheckBox JRadioButton JComboBox JList Java Programming: From Problem Analysis to Program Design, 5e 39 JTextArea Can collect multiple lines of input from user Can display multiple lines of output Pressing Enter key separates lines of text Each line ends with newline character \n Derived from class JTextComponent Java Programming: From Problem Analysis to Program Design, 5e 40 20
