What is the significance of the Garbage Collector in Java? How does it work?

The Garbage Collector is an automatic memory management tool that reclaims memory by removing unused heap objects.

• The Garbage Collector tracks all references to each object on the heap.
• If there are no references left for an object, it is marked as safe for deletion.
• In the next round of garbage collection, the collector checks all objects marked for deletion and reclaims memory from those objects.
