Java Stream API for Bulk Data Operations on Collections; Java Time API; Collection API improvements; Concurrency API improvements; Java IO improvements; Miscellaneous Core API improvements; Let’s have a brief look on these Java 8 features. I will provide some code snippets for better understanding, so if you want to run programs in Java 8, you will have to setup Java 8 environment by following steps.

interface MyInterface { /* * This is a default method so we need not to implement this method in the implementation classes */ default void newMethod() { System.out.println("Newly added default method in Interface"); } /* * This is a static method.

Particularly offensive to me is the fact that Stream does not implement Iterable (despite actually having method iterator) and cannot be used in a for-each, only with a forEach(). I recommend casting Streams into Iterables with (Iterable<T>)stream::iterator.

This post will introduce various features and changes in Java SE 8, and will cover default methods, functional interfaces, lamda expressions, and streams.

Java uses the concept of stream to make I/O operation fast. The java.io package contains all the classes required for input and output operations. We can perform file handling in java by Java I/O API. Stream. A stream is a sequence of data.In Java a stream is composed of bytes.
