As we learned in the preceding section, there isn't one but four different garbage collectors. Each one has its own advantages and disadvantages. The one thing these collectors have in common is that they split the managed heap into different segments with the assumption that objects are short-lived and should be removed shortly. Let's see four different algorithms of GC.
GC methods and policies
Serial collector
The Serial collector is the simplest GC implementation, mainly designed for single-threaded environments and small heaps. This GC implementation freezes all application threads whenever it's working. Hence, it's not a good idea to use it in multithreaded applications, such as server environments...
