Garbage Collection - Tutorial

Garbage Collection - Tutorial  
ABSTRACT
 
One of the compelling features of Java is its support for memory management by means of a garbage collector, which automatically releases heap memory that is no longer used. Usually, Java programmers don’t care a lot about the garbage collector and treat it as a black box that simply does its job.  However, garbage collection does not come for free; it takes time and consumes resources.  Occasionally, it turns out that the garbage collector contributes to the performance degradation of an application; basically the application spends more time with garbage collection than necessary.  In those cases, it is helpful to understand the garbage collector’s functionality and to know how to control and tune its behavior. 

In this tutorial we will first give an overview of the classic garbage collection algorithms (reference counting, mark & sweep, mark & compact, copying, generational, incremental, and concurrent GC) before we delve into the more practical issue of exploring the tuning options that the Sun JVM has to offer. This includes new tuning options introduced in Java 5.0 as "garbage collector ergonomics".
