Garbage Collection is process of reclaiming the runtime unused memory automatically. In other words, it is a way to destroy the unused objects. To do so, we were using free () function in C language and delete () in C++. But, in java it is performed automatically. So, java provides better memory management. fileslib. Garbage Collection as a Memory Management Technique. Garbage collection is one of the memory management techniques used in programming languages. It is an automatic memory management technique added as a feature for many programming languages. The garbage collector collects or reclaims the memory allocated to variables or objects but is no longer in use by the program; this is also termed garbage. Manual freeing of memory is not needed as garbage collection automatically releases the memory space after it is no longer required. Garbage collection handles memory allocation safely so that no objects use the contents of another object mistakenly. The constructors of newly created objects do not have to initialize all the data fields as garbage collection clears the memory of objects that were previously released. Periodically the garbage collector will run a garbage collection which checks if objects in memory are still reachable, remove objects that are not reachable, and reorganize the objects that are still alive to make more efficent usage of memory and improve future garbage collections. Garbage collectors considerably reduces the amount of time and effort developers must spend managing memory.
You can trigger a manual garbage collection process by using the gc.collect () method: >>> gc.get_count() (595, 2, 1) >>> gc.collect() 577 >>> gc.get_count() (18, 0, 0) Running a garbage collection process cleans up a huge amount of objects—there are 577 objects in the first generation and three more in the older generations.
