For Java garbage collection mechanism, this long ago learned, and understand, for a long time not to be thrown back to the island of the claw, here or down, convenient to check again later, do not waste too much time.To understand the Java garbage collection mechanism, you need to know the differences between versions
in which the system automatically processes memory-garbage collection (Gc,garbage Collection). Now many platforms and languages support garbage collection mechanisms such as JVMs, CLR, Python
concept of root set. The Garbage Collector Based on the tracing algorithm scans the root set to identify which objects are reachable and which objects are not reachable, and marks the reachable objects in some way, for example, you can set one or more places for each reachable object. In the scanning and identification process, the garbage
