3 sty 2023 · Timers. Timers are used to perform actions periodically, after an initial delay, or both. Also, actions can be performed only once, if desired. Here are some reminders regarding the two flavors of timers, as used in Swing applications: javax.swing.Timer.
A javax.swing.Timer object calls an action listener at regular intervals or only once. For example, it can be used to show frames of an animation many times per second, repaint a clock every second, or check a server every hour.
A Swing timer (an instance of javax.swing.Timer) fires one or more action events after a specified delay. Do not confuse Swing timers with the general-purpose timer facility in the java.util package.
You can find further documentation and several examples of using timers by visiting How to Use Timers, a section in The Java Tutorial. For more examples and help in choosing between this Timer class and java.util.Timer, see Using Timers in Swing Applications, an article in The Swing Connection.
