• Young Generation, which is further divided in to:

    • Eden - the region when the objects are usually allocated when they are created;
    • Survivor Spaces - (to and from - one of which is always empty) - responsible for storing all live object remaining after collecting Young Generation (process is repeated several times until objects are finally considered old enough);
  • Old Generation - (Tenured Space) - responsible for live objects remaining after running GC on Survivor Spaces - those would be long-lived objects (usually user connections and associated data);
