Kas saaksite selgitada Java automaatse mälu haldamise mehhanismi, mida tuntakse kui prügikoristajat?

Java's Garbage Collector (GC) is an automatic memory management mechanism that frees memory occupied by objects that are no longer used by the program.

When objects are created, they are placed in the heap. If there are no more references to an object from active code, it is considered unreachable and can be deleted.

The garbage collector periodically scans the heap, identifies such objects, and releases the memory they occupy, preventing memory leaks and easing the developer's task in memory management.

The process generally looks like this:

1. Objects are created and used.
2. When references to an object are lost, it becomes a candidate for deletion.
3. GC is triggered and cleans up the memory.

This allows you not to worry about explicitly deleting objects, as in languages with manual memory management.
