A comprehensive technical guide to selecting Java garbage collectors (GC) based on workload characteristics across JDK 8-25. Covers five primary workload categories: microservices, legacy JEE, stateful UI, data-intensive batch processing, and ultra-low latency systems. Provides mathematical tuning models, performance trade-offs, and migration strategies from legacy collectors (CMS, Parallel) to modern options (G1, ZGC, Generational ZGC). Includes detailed analysis of throughput vs. latency trade-offs, memory overhead, CPU costs, and version-specific optimization roadmaps. Emphasizes that Generational ZGC (JDK 21+) represents a significant advancement for high-performance workloads, while G1 remains optimal for memory-constrained environments.
