Mark-Compacting Approach

Mark Compacting approach combines Mark-sweeping and copying in a way that to solve the drawback of requiring twice as much memory in copying collectors. First, reachable objects are marked, then a compacting step relocates the reachable (marked) objects towards the beginning of the heap area. So all the live objects are at the beginning of heap area.
