GC overview

In the intricate landscape of JVM internals, the GC role stands as a critical component, influencing the efficiency and reliability of Java applications. Our exploration delves into the fundamental concept of garbage collection and its pivotal role in managing memory within the JVM.

At its core, the purpose of the GC is to automatically reclaim memory occupied by objects no longer in use by the program. In languages such as Java, which employ automatic memory management, developers are spared the burden of explicitly deallocating memory, enhancing productivity and reducing the likelihood of memory-related errors.

Imagine a scenario where each dynamically allocated object had to be manually deallocated by the programmer. Not only does this introduce a considerable cognitive load, but it also opens the door to memory leaks and inefficiencies. In the absence of a GC, the responsibility of memory management falls entirely on the developer’s shoulders, increasing...
