Question

Quizplus · Accepted Answer

A lock is used to ensure mutual exclusion or thread safety in multi-threaded environments where multiple threads may access the same object and modify its state concurrently. It ensures that only one thread can have access to the object's methods at one time, preventing race conditions and maintaining consistency. The other options, such as increased sharing, speed increase, and privacy protection, are not the primary purpose of using a lock in an object's methods.
