What are some tools to detect memory leaks?

Tools like VisualVM, Eclipse Memory Analyzer, and Valgrind can help detect memory leaks by analyzing memory usage and identifying unreferenced objects.

How can I prevent memory leaks in my applications?

To prevent memory leaks, ensure to nullify references when objects are no longer needed, use weak references, and regularly profile your application for memory usage.
