Java Memory Management, with its integral garbage collection, is one among the language's finest achievements. It lets developers build new objects without having to worry much about memory management, allocation and deallocation which is due to the fact that the garbage collector automatically reclaims memory for use. This allows quicker application development with less boilerplate code, whereas eliminating memory leaks and different memory-related issues.
Java garbage collection appears to work well, making and removing several objects. Most of the times all memory-management problems are resolved, but typically at the cost of making serious performance issues. Creating a garbage collection convertible to all or any sorts of situations has led to an intricate and hard-to-optimize system. To understand comprehensive knowledge of working of Java's garbage collection, it is recommended to learn Java first to understand the fundamentals of Java.
Most of the times people usually think that garbage collection collects and discards dead objects. But actually what happens is Java garbage collection does the opposite! Typically the live objects are tracked and everything else moved to garbage. This basic misunderstanding will cause several performance issues.
