Java Yield Use Cases Explained
In Java, the yield keyword is used for thread cooperation, allowing the current thread to pause execution and give up CPU resources to other threads. Yield scenarios include:
- Controlling thread priority: In cases where multiple threads have the same priority, you can use the “yield” command to relinquish CPU resources to other threads to prevent one thread from monopolizing resources.
- Cooperation between threads: In multi-threaded programming, there are times when multiple threads need to be executed in a certain order, and we can use yield to control the execution sequence of threads.
- Improve the efficiency of thread execution: When a thread is working on a long task and other threads have quicker tasks to complete, using yield at appropriate points in the long task can give other threads a chance to run, ultimately boosting overall execution efficiency.
It is important to note that the yield method only suspends the execution of the current thread and does not guarantee that other threads will immediately execute. The specific thread scheduling is still determined by the operating system.
