Question
Select the correct answer
What does not prevent JVM from terminating?
Options:
- Process
- User Thread
- JVM Thread
- Daemon Thread
Solution
The correct answer is Daemon Thread.
Here's why:
-
Process: A running Java application is considered a process, and JVM will not terminate until this process finishes its execution.
-
User Thread: User threads (also known as non-daemon threads) are the threads in the foreground that perform the main operations of the application. JVM waits for all user threads to complete their execution before it terminates.
-
JVM Thread: JVM threads are the threads created by JVM for its internal operations. JVM will not terminate until these threads finish their execution.
-
Daemon Thread: Daemon threads are the threads that run in the background and perform tasks such as garbage collection. The JVM does not wait for daemon threads to finish their execution. If all user threads finish their execution, JVM can terminate even if daemon threads are still running. Therefore, Daemon Thread does not prevent JVM from terminating.
