Generational Garbage Collection in HotSpot
This section describes the generational garbage collection architecture used in the HotSpot JVM. Young Generation stores objects with shorter lives and Tenured Generation stores objects with longer lives. 2022-10-01, ∼268🔥, 0💬

Tenured Generation Collection - Major GC
This section describes basic steps of a Tenured Generation Collection, also called a Major GC, which uses a simple 3-step Mark-Sweep-Compact algorithm on the entire Tenured Generation. 2022-10-01, ∼268🔥, 0💬

Young Generation Collection - Minor GC
This section describes basic steps of a Young Generation Collection, also called a Minor GC. The Young Generation is divided into 3 areas: Eden, Survivor Space 'From' and Survivor Space 'To'. 2022-10-01, ∼268🔥, 0💬
