What are some effective Java performance tuning techniques?

What are some effective Java performance tuning techniques?

There are several techniques to improve Java performance, such as optimizing garbage collection, using efficient data structures, and minimizing object creation.

Can you explain how garbage collection optimization works?

Garbage collection optimization involves tuning the JVM's garbage collector settings to reduce pause times and improve throughput. This can include selecting the right garbage collector and adjusting parameters like heap size.

What data structures are considered efficient in Java?

Efficient data structures in Java include ArrayList for dynamic arrays, HashMap for key-value pairs, and LinkedList for frequent insertions and deletions.

How can I minimize object creation in my Java application?

To minimize object creation, you can reuse objects, use primitive types instead of wrapper classes, and implement object pools for frequently used objects.
