Java 8, released on March 18, 2014, introduced major enhancements that transformed Java into a more functional programming-friendly language while improving APIs, performance, and developer productivity.
1. Lambda Expressions Enable concise implementation of functional interfaces (Single Abstract Method interfaces). They simplify iteration, filtering, and data manipulation.
List<String> names = Arrays.asList("John", "Jane", "Jack");
names.forEach(n -> System.out.println(n));

2. Functional Interfaces Interfaces with a single abstract method, annotated with @FunctionalInterface. Examples: Predicate<T>, Function<T,R>, Supplier<T>, Consumer<T>.
3. Method References A shorthand for lambdas that call existing methods. Types:
Static: Math::max
Instance: str::length
Arbitrary object: String::toLowerCase
Constructor: ArrayList::new
4. Stream API Provides a declarative way to process collections with operations like filter, map, reduce, and supports parallel processing.

Lambda Expressions:
Lambda expressions provide a clear and concise way to represent a method of a functional interface (an interface with a single abstract method). They enable functional programming in Java, allowing developers to write more readable and less verbose code. For example, a lambda expression can replace an anonymous class implementation of a functional interface.
Stream API:
The Stream API allows for efficient data manipulation and processing. It provides a functional approach to processing sequences of elements (like collections) and supports operations such as filtering, mapping, and reducing. This makes it easier to work with large data sets and perform complex data transformations in a more readable manner.
Optional Class:
The Optional class is a container object which may or may not contain a value. It helps to avoid NullPointerExceptions by providing a way to express the absence of a value without using null. This encourages better handling of optional values and improves code readability.
Default and Static Methods in Interfaces:
Java 8 allows interfaces to have default methods (methods with a body) and static methods. This means that new methods can be added to interfaces without breaking existing implementations. Default methods provide a way to evolve interfaces while maintaining backward compatibility.
Method References:
Method references provide a shorthand notation of a lambda expression to call a method. They enhance the readability of the code by allowing developers to refer to methods directly without needing to write a full lambda expression.
New Date and Time API:
Java 8 introduced a new Date and Time API (java.time package) that addresses the shortcomings of the old java.util.Date and java.util.Calendar classes. This new API is more comprehensive and provides better handling of date and time operations.
Nashorn JavaScript Engine:
Java 8 includes a new lightweight JavaScript engine called Nashorn, which allows developers to embed JavaScript code within Java applications and execute it with high performance.
Concurrency Enhancements:
Java 8 introduced new classes in the java.util.concurrent package, such as CompletableFuture, which simplifies asynchronous programming and allows for better handling of concurrent tasks.These features collectively enhance Java's capabilities, making it more powerful and easier to use for developers, especially in the context of functional programming and data processing. For a deeper dive into each feature, you can refer to resources like GeeksforGeeks and W3Schools.
