Quick Answer
Java memory optimization: use primitives instead of wrappers where possible, avoid unnecessary object creation, reuse objects (object pools for expensive objects), use StringBuilder instead of String concatenation in loops, be aware of autoboxing in collections, use weak/soft references for caches, tune GC with appropriate heap sizes and GC algorithm for your workload.
Answer
Use primitive types when possible. Avoid unnecessary object creation. Apply lazy initialization and caching. Choose efficient collections. Minimize object retention to help GC.
