What are some specific techniques I can use?

You can minimize object creation, use object pooling, and tune JVM parameters like -Xms and -Xmx to manage heap size effectively.

How do I monitor garbage collection performance?

You can use tools like VisualVM or Java Mission Control to monitor garbage collection performance and analyze memory usage.

Are there any common pitfalls to avoid?

Yes, avoid creating too many short-lived objects, as this can lead to frequent garbage collections, impacting performance.
