The java.util.concurrent.Semaphore class is a synchronization mechanism provided by the Java programming language. It allows multiple threads to access a certain resource or a fixed number of resources simultaneously. A Semaphore maintains a set of permits and manages access to the resource based on the available permits. Threads can acquire permits from the Semaphore to gain access to the resource and release them when they are done. If no permits are available, the acquiring thread will wait until a permit becomes available. Semaphores are often used in concurrent programming scenarios where limited resources need to be shared among multiple threads in a controlled manner to prevent race conditions and ensure thread safety.
