Java Semaphore is a synchronization object used to manage access to shared resources by multiple threads. It controls access by maintaining a set of permits, where a thread can acquire a permit before proceeding and release it when finished. Introduced in Java 2004 with Java 5, Semaphore is part of the java.util.concurrent package and is particularly useful in controlling resource pooling and limiting concurrent access to critical sections in multithreaded programs.
