JAVA 8 Features Tutorial | Functional Interfaces | Lambda Expressions | Optional Class | Stream API
Показать описание
Java 8 Version introduced a significant number of features that changed the way developers write Java applications. Here are some of the key features:
Default and Static Methods in Interfaces: Java 8 allows you to define default and static methods within interfaces. This enables you to add common functionality to interfaces without breaking existing implementations.
Functional Interfaces: These interfaces have a single abstract method, making them ideal targets for lambda expressions. Java 8 introduced some built-in functional interfaces like Predicate, Function, and Consumer.
Lambda Expressions: These concise anonymous functions allow you to write cleaner and more functional code. They are particularly useful with the Stream API (discussed below).
Optional Class: This class helps deal with null references in a more robust way. It provides methods to check for null values and handle them safely.
Stream API: This API provides a powerful way to process collections of data in a declarative manner. Streams allow you to filter, map, and reduce collections using a chain of operations.
