Java yield Keyword: Purpose Explained

In Java, the purpose of the yield keyword is to relinquish the current thread’s execution rights, allowing other threads with the same priority to have a chance to execute. By using the yield keyword, programs can facilitate cooperation between multiple threads, improving the efficiency and fairness of thread execution.

Specifically, when a thread calls the yield method, it suspends the currently executing thread and gives the chance for other threads to run. However, it does not guarantee that other threads will immediately execute – it just increases the probability of them being selected. Once the other threads finish executing, the thread that originally called the yield method can continue running.

It is important to note that the yield method is just a suggestion and not mandatory. Therefore, the specific outcome still depends on the operating system’s scheduler. In some cases, calling the yield method may have no effect.

In summary, the purpose of the yield keyword is to release the current thread’s execution rights, increasing the probability of other threads being selected, thereby improving the efficiency and fairness of thread execution.
