What is the difference between destructor and garbage collector in Java?

A destructor is a method in a program that is used to clean up after a class when it is no longer in use. This usually involves freeing up memory, deleting resources, and performing other necessary clean-up operations. A garbage collector is an automated process that reclaims memory allocated to objects that are no longer used in a program. Unlike destructors, garbage collectors are not tied to a particular class, but rather are handled by the JVM (Java Virtual Machine). Garbage collectors are used to manage memory in programs by identifying and removing as much as possible unused objects in order to free up space in the computer's memory.
