What is the main objective of garbage collection in java?

By | March 5, 2023

The main objective of garbage collection in Java is to automatically manage the memory allocation and deallocation process of objects at runtime.

In Java, when an object is created, it is allocated memory in the heap. However, once an object is no longer needed or is no longer accessible by any part of the program, that memory becomes unnecessary and can be reclaimed. Garbage collection is the process of identifying and freeing up memory that is no longer being used by the program.

By automatically managing memory allocation and deallocation, garbage collection helps to prevent memory leaks, where memory is allocated but never freed, and reduces the likelihood of runtime errors due to null pointer exceptions and other memory-related issues. This makes Java a more secure and reliable programming language, with less risk of crashes or system instability due to memory issues.
