When an object is assigned to null, it indicates that there are no longer any references pointing to that object. In the context of garbage collection, this means that the object becomes eligible for garbage collection. The garbage collector is responsible for automatically reclaiming memory that is no longer in use, and when an object has no references, it can be identified as such. Once an object is discovered to have no active references, the garbage collector can reclaim the memory at some point in the future. It is important to note that just being eligible for garbage collection does not guarantee immediate deallocation; it means that the object will eventually be cleared when the garbage collector runs. In this scenario, since the object is set to null and no other references exist, it is indeed marked as eligible for garbage collection. This helps manage memory efficiently, especially in environments like Java or C#, where memory must be managed dynamically during runtime.
