The Evolution of Garbage Collection Algorithms in Java
summary
Survey of Java garbage collection: explains why efficient memory allocation and reclamation matter for performance, then reviews historical and current GC algorithms used in the Java platform (past and present collectors and their approaches to allocation, tracing, and reclamation). Focus is on concrete GC techniques and their evolution rather than broader Java topics.
