Java WeakReference is a class that provides a reference to an object that does not prevent it from being garbage-collected. It is part of Java's java.lang.ref package and is used in scenarios like caching, where an object should be eligible for garbage collection if there are no strong references to it. Introduced in Java 1997 with Java 1.2, WeakReference is often used to avoid memory leaks in long-running applications.
