Java8
Java 8 was introduced to modernize Java by adding functional programming features, improving performance, and making the language more concise, readable, and expressive. It aimed to reduce boilerplate code, improve parallel processing, and enable more declarative coding styles—especially important for handling large data collections and multi-core processors.
