What is 'daemon' thread in Java?

  1. A high-priority thread

  2. A background service thread

  3. A thread that runs in debug mode

  4. A thread that cannot be stopped

The correct answer is: A background service thread

A 'daemon' thread in Java is a type of thread that runs in the background and provides services to other threads. This means that it is not a high-priority thread that has preferential access to CPU resources. Option A is incorrect because while 'daemon' threads may have higher priority than user threads, they are not considered high-priority threads in the traditional sense. Option C is incorrect because 'daemon' threads can run in either debug or non-debug mode. Option D is also incorrect because 'daemon' threads can be stopped by the JVM when all user threads have finished executing.
