Data structures play a crucial role in computer science and software engineering, enabling efficient storage and retrieval of information. In this discussion, let's compare and contrast two important data structures in Java: AVL trees and hashing.

Given a specific problem or application requirement, how would you decide whether to use AVL trees or hashing in Java? Discuss the factors to consider and the trade$-$offs involved. Explore real$-$world applications where AVL trees or hashing are particularly well$-$suited. Discuss examples from databases, caching systems, and other software engineering domains.

Engage in thoughtful discussions and exchange ideas. Respond to two of your classmates' posts by providing valuable feedback.
