Web22 jul. 2024 · Introduction. Garbage Collection (GC) is a form of automatic memory management. Its aim is to reclaim garbage or memory occupied by objects that are no longer in use by the program. Garbage collection was invented by John McCarthy around 1959 to simplify manual memory management in Lisp . It has a longer history than Java. Web30 mei 2015 · Tracing garbage collection (i.e. what is most often referred to as simply garbage collection) involves keeping a list of all root objects (i.e. those stored in global variables, the local variables of the main procedure, etc) and tracing which objects are reachable (marking each object encountered) from those root objects. monkey meadows wallpaper
