• It is exactly same as HashMap except below difference:
    • In the case of HashMap, even though object doesn’t have any reference it is not eligible for GC if it is associated with HashMap i.e HashMap dominates GarbageCollector
    • But in the case of weak hashmap if the object doesn’t contain any references, it is eligible for GC even though the object associated with WeakHashMap i.e GarbageCollector dominates WeakHashMap
