What are some best practices for optimizing Java applications?
To optimize Java applications, consider using efficient data structures, minimizing object creation, and leveraging the JVM's garbage collection.
Can you explain how garbage collection works in Java?
Garbage collection in Java automatically frees up memory by removing objects that are no longer in use, helping to prevent memory leaks.
What data structures are most efficient for performance?
Using HashMap for key-value pairs, ArrayList for dynamic arrays, and LinkedList for frequent insertions and deletions can enhance performance.
How can I measure the performance of my Java application?
You can use profiling tools like VisualVM or JProfiler to analyze memory usage, CPU load, and identify bottlenecks in your application.
