Java's garbage collection optimizes memory management. Mastering it boosts performance. Key techniques: G1GC, object pooling, value types, and weak references. Avoid finalize(). Use profiling tools. Experiment with thread-local allocations and off-heap memory for best results.

Microservices offer scalability but require resilience. Netflix Hystrix provides circuit breakers, fallbacks, and bulkheads for Java developers. It enables graceful failure handling, isolation, and monitoring, crucial for robust distributed systems.

ELK stack transforms logging: Elasticsearch searches, Logstash processes, Kibana visualizes. Structured logs, proper levels, and security are crucial. Logs offer insights beyond debugging, aiding in application understanding and improvement.

Java's security features fortify apps against cyber threats. Security Manager, Access Controller, JCA, JAAS, and JSSE provide robust protection. Custom security implementations, logging, and input validation enhance defenses. Java's design inherently prevents common vulnerabilities.

Java's advanced I/O capabilities offer powerful tools but can be tricky. Key lessons: use try-with-resources, handle exceptions properly, be mindful of encoding, and test thoroughly for real-world conditions.
