What are the differences between data structures in C++ and Java?

C++ and Java have different approaches to data structures. C++ uses pointers and allows manual memory management, while Java has built-in garbage collection and uses references. This affects how you implement structures like linked lists and trees.

Can you give me an example of a linked list implementation in both languages?

Sure! In C++, a linked list node might look like this:

struct Node {
    int data;
    Node* next;
};

In Java, it would be:

class Node {
    int data;
    Node next;
}

What about the performance differences between them?

C++ generally offers better performance due to lower-level memory management, but Java's performance has improved significantly with JIT compilation. The choice often depends on the specific use case.

Which language is better for implementing complex data structures?

It depends on your needs. C++ gives you more control and efficiency, while Java provides ease of use and safety features. For complex data structures, C++ might be preferable if performance is critical.
