Objects are created and Java allocates system memory for storing that object. If the object is not used, the memory allocated to it is considered wasted. This is something we want to avoid. Even with small applications, this type of wasted memory can lead to poor performance and even out-of-memory issues.
Our goal is to deallocate or release the memory, any previously allocated memory that we no longer need. Fortunately, with Java, there is a mechanism for handling this issue. It is called garbage collection.
When an object, such as our myObjectName example, no longer has any references pointing to it, the system will reallocate the associated memory.
