Why Are Strings Immutable in Java? The Full Explanation You Need.

It's a classic Java interview question, but it's also a critical piece of the language's design. In this comprehensive guide, we're not just telling you that Strings are immutable—we're showing you why it's one of the best decisions the creators of Java ever made.

In this video, we'll cover:

What "immutability" actually means (and what happens when you "change" a String).

Memory Efficiency: A deep dive into the String Constant Pool and how it saves valuable heap space.

Security: How immutable Strings protect your application from security vulnerabilities.

Performance & Caching: Why systems like HashMaps depend on Strings being immutable.

Thread Safety: How immutability makes your multi-threaded code simpler and safer.

Whether you're a computer science student, preparing for a technical interview, or just want to become a better Java developer, this video will clear up all your confusion.
