Java 8 features and benefits
Lambda expressions: Lambda expressions are anonymous functions that can be used as parameters or variables. They enable a concise and functional style of programming that can simplify complex code and improve readability.
Method references: Method references are a shorthand way of referring to existing methods using the :: operator. They can be used in place of lambda expressions when the method name is already known.
Functional interfaces: Functional interfaces are interfaces that have only one abstract method. They can be used as targets for lambda expressions or method references. Java 8 provides many built-in functional interfaces for common operations, such as Predicate, Consumer, Supplier, Function, etc.
Stream API: Stream API is a new way of processing collections of data in a declarative and parallel manner. It supports various operations such as filtering, mapping, reducing, sorting, etc. that can be chained together to form pipelines.
Default methods: Default methods are methods that have a default implementation in an interface. They allow adding new functionality to existing interfaces without breaking backward compatibility.
Date/Time API: Date/Time API is a new set of classes and interfaces that provide a comprehensive and consistent model for handling date and time in Java. It supports various formats, time zones, calendars, periods, durations, etc.
Nashorn JavaScript engine: Nashorn JavaScript engine is a new implementation of the JavaScript language that runs on the Java virtual machine. It allows executing JavaScript code from Java applications or embedding Java code in JavaScript scripts.
These are just some of the highlights of Java 8 features. There are many more improvements and additions that make Java 8 a powerful and modern platform for developing applications. For more details, you can refer to , , or .
