Java Memory Heap
The Sun JVM heap is divided into two parts:
• The Old Generation, sometimes called the “Tenured Space.”
• The Young Generation, sometimes called the “New Space.”
The Young Generation is further subdivided into three partitions: Eden and two survivor spaces, called the “From Space” and the “To Space.” Objects are created in Eden. When Eden is full, live objects are copied to the From Space. When Eden is full again, objects in the From Space are copied to the To Space. Finally, if the object survives when Eden is full, the object is moved to the Old Generation.
