Java: Stack with weak references Code Answer

Hello Developer, Hope you guys are doing great. Today at Tutorial Guruji Official website, we are sharing the answer of Java: Stack with weak references without wasting too much if your time.

The question is published on by Tutorial Guruji team.

In Java there is a data structure called a WeakHashMap that stores weak references as keys. Whenever the weak references are taken out of memory the entry is removed from the map.

If I have a data structure such as a Stack or a Set where I am storing weak references, will their entries be automatically removed when the weak reference is taken out of memory?

Below is an example of a Stack that stores weak references.

Stack<WeakReference<Object>> objStack = new Stack<WeakReference<Object>>();


Yes. What you’re describing is a property of weak references in general, not WeakHashMap specifically.

From the API:

Suppose that the garbage collector determines at a certain point in time that an object is weakly reachable. At that time it will atomically clear all weak references to that object…
