Question

What is the best way to release a thread object once you are done using it:

A.) Assign null to Thread variable.

B.) Use stop() method of Thread class.

C.) Use suspend() method of Thread class.

D.) Use resume() method of Thread class.

Answer 1

The best way to release a thread object after use is to assign null to the Thread variable, allowing the garbage collector to reclaim the memory. The stop() and suspend() methods are not recommended because they are unsafe and deprecated.

Step-by-step explanation:

The best way to release a thread object in Java once you are done using it is to ensure that the thread completes its run method. Threads in Java are garbage collected when there are no more references to them, and they have completed their execution. Therefore, the correct answer is: A.) Assign null to Thread variable. This allows the garbage collector to reclaim the thread object's memory when it is no longer in use. It's important to note that you do not need to manually stop a thread using deprecated methods like stop() or suspend(), as these are unsafe and can leave shared data in an inconsistent state. These methods are also deprecated. Instead, you should write your thread code in a way that allows the thread to complete naturally, for instance, by finishing the run method or by responding to an interrupt.
