What is the role of garbage collector in memory management in automatic programming systems?

The Garbage Collector (GC) in automatic programming systems is responsible for automatic memory management. Its role is to detect and free memory that is no longer used by the program to prevent memory leaks and overflow.

In Android (and Java in general), the programmer does not manually manage memory; instead, the GC periodically checks objects in memory and deletes those that are no longer referenced. This frees up resources and allows the application to run efficiently without crashes due to lack of memory.

For example, if you create an object and then stop referencing it, the garbage collector will eventually delete this object, freeing up memory.

Thus, GC simplifies development by reducing the risk of errors related to memory management.
