■ Caution The JPasswordField also has a deprecated read-only text property, which you should avoid

using. You should use the password property instead, because it returns a char[] that can be cleared
immediately after usage. A String must wait for the garbage collector to dispose of it.

Customizing a JPasswordField Look and Feel
The JPasswordField is a subclass of a JTextField . It has the same appearance under all the
predefined look and feel types as the JTextField (see Figure 15-15). The one difference is that
the current echoChar property setting masks the content. This is shown in Figure 15-16. The top
text component is a JTextField ; the bottom one is a JPasswordField .
