What are the key differences between Java Collections and C++ STL?

Java Collections Framework provides a set of classes and interfaces for storing and manipulating groups of data, while C++ Standard Template Library (STL) offers a collection of template classes and functions for similar purposes. Key differences include syntax, memory management, and performance.

Can you explain the memory management differences?

In Java, memory management is handled by the garbage collector, which automatically deallocates memory. In contrast, C++ requires manual memory management, where developers must allocate and deallocate memory using 'new' and 'delete'.

Which one is better for performance?

Performance can vary based on the use case. C++ STL generally offers better performance due to lower-level memory management and less overhead, while Java Collections may be easier to use and integrate with other Java features.

Are there any specific use cases where one is preferred over the other?

Yes, C++ STL is often preferred in systems programming and performance-critical applications, while Java Collections are favored in enterprise applications and environments where ease of use and safety are priorities.
