Java 8 New Features

Java 8 was a significant release that introduced several new features to the Java programming language. Some of the notable features include:

Lambda expressions: These enable you to treat blocks of code as if they were method arguments, making it easier to write code that works with collections of data.

Stream API: This API allows you to process collections of data in a declarative way, making it easier to write efficient and maintainable code.

Default methods: This feature allows interfaces to have code implemented in them, which can be inherited by classes that implement the interface.

Optional class: This is a utility class that is used to represent the absence of a value in situations where a null value would otherwise be used.

Nashorn JavaScript engine: This is a new engine for executing JavaScript code that is built into the Java runtime.

Concurrent Accumulators: These are classes that allow you to perform atomic updates on variables that are shared by multiple threads.

Date and Time API: This API provides a more intuitive way to work with dates and times, and replaces the old java.util.Date class.

Other features: Java 8 also includes several other features, such as improved type inference, a new way to work with strings, and improved support for parallelism and concurrency.
