Description: A daemon thread in Java is a type of thread that runs in the background and has a lower priority compared to normal user threads. Its main function is to perform non-critical tasks for the application, such as garbage collection or background task management. Unlike user threads, daemon threads do not prevent the application from closing; that is, if all user threads have finished executing, the Java Virtual Machine (JVM) will stop, even if there are daemon threads running. This makes them a useful tool for tasks that need to run continuously but are not essential for the program’s completion. Daemon threads are created using the Thread class and are configured as daemons using the setDaemon(true) method. This feature allows developers to optimize resource usage and improve the efficiency of their applications, ensuring that background tasks are performed without interfering with the main program execution.
