each garbage collection, only Small Amount survival, then choose the replication algorithm, only need to pay a small number of surviving objects copy cost can be completed collection. In the old age, because of the high survival rate of the object and the lack of additional space to guarantee it, it must be recycled using the "mark-clean" or "mark-sweep" algorithm. Garbage collector　　if the collection algorithm is the method of memory recycling, the garbage collector is the specific implementat
