Java8 was released by Oracle Bone Inscriptions Company on March 18, 2065438. It not only supports functional programming, but also adds operations such as date API and StreamAPI. Here, Fat Tiger will show you some new features of Java8.
The ava8API adds a new abstraction called Stream, which allows you to process data declaratively. This style regards the set of elements to be processed as a stream, which is transmitted in the pipeline and can be processed at the nodes of the pipeline, such as filtering, sorting, aggregation and other operations.
Java8 adds the default method of the interface. Simply put, the default method is that the interface can have an implementation method, and there is no need to implement the method of the class.
