Tutorial: Java theory and practice: A brief history of garbage
collection
In this installment of Java theory and practice, Brian Goetz describes the most common techniques for garbage collection.
Tutorial Details:
the garbage collection strategies employed by the 1.4 JVM, some performance implications of various garbage collection strategies, and how to assist the garbage collector to yield better performance.
The benefits of garbage collection are indisputable -- increased reliability, decoupling of memory management from class interface design, and less developer time spent chasing memory management errors. The well-known problems of dangling pointers and memory leaks simply do not occur in Java programs. However, garbage collection is not without its costs -- among them performance impact, pauses, configuration complexity, and nondeterministic finalization.
An ideal garbage collection implementation would be totally invisible -- there would be no garbage collection pauses, no CPU time would be lost to garbage collection, the garbage collector wouldn\'t interact negatively with virtual memory or the cache, and the heap wouldn\'t need to be any larger than the residency of the application.
