Lambda expressions, also known as closures, are anonymous functions that can be treated as values. They enable developers to write concise, expressive code, making it easier to work with data collections. Lambda expressions are a key component of functional programming, a paradigm shift from Java’s traditional object-oriented approach.
Functional Programming
Functional programming is a programming paradigm that emphasizes immutability, recursion, and higher-order functions. Java 8’s functional programming features, including lambda expressions, method references, and functional interfaces, allow developers to write more concise, more efficient, and more expressive code.
Java Time API
The Java Time API, also known as JSR-310, is a comprehensive API for working with dates and times. It provides a more intuitive and flexible way of handling date and time calculations, making it easier to work with datetime-related data.
Nashorn JavaScript Engine
Nashorn is a high-performance JavaScript engine that replaced the Rhino engine used in previous Java versions. Nashorn provides better performance, improved security, and enhanced compatibility with modern JavaScript standards.
Stream API
The Stream API is a powerful tool for working with data collections. It enables developers to process large datasets in a more efficient, more concise, and more expressive way, making it an essential feature for data-intensive applications.
Optional Class
The Optional class is a new utility class that helps developers avoid null pointer exceptions. It provides a more elegant way of handling optional values, making code more robust and less prone to errors.
