Java Thread Self-Join Deadlock

Question

Which of the following best describes the outcome of the `Thread.currentThread().join()` call in the code segment below?

```java
public class SelfJoin {
    public static void main(String[] args) {
        try {
            // The current thread waits for its own termination
            Thread.currentThread().join();
        } catch (InterruptedException e) {
            Thread.currentThread().interrupt();
        }
        System.out.println("This line will never be printed.");
    }
}
```

Accepted Answer

Calling join() on the current thread causes it to wait for itself indefinitely, resulting in a deadlock.

Answer

The code will throw a runtime exception unrelated to deadlock because join() is misused here.

Answer

join() introduces a brief sleep that delays the thread momentarily before resuming execution.

Answer

Using join() on the current thread is a best practice for ensuring proper synchronization.
