Java timer scheduleatfixedrate

Java provides built-in timer functionality through the and classes. These allow us to schedule tasks for future execution or repeated execution at fixed intervals. Let’s explore how to use timers in Java.

The first timer will fire ~2 seconds after we start the program, but the second should be cancelled before it has a chance to fire.

In this Java example, we use to create timers and to define the tasks that should be executed when the timers fire.

The method is used to set when the timer should fire.

We use to pause the main thread, allowing time for the timers to fire or to demonstrate that a cancelled timer doesn’t fire.

Note that in Java, we need to explicitly cancel the Timer objects at the end to clean up the timer threads.

This is not necessary in languages with garbage collection for threads, but it’s a good practice in Java to prevent potential memory leaks.
