Want to get more out of the Java language and platform? In this platform- and framework-neutral course, instructor Bethan Palmer digs into some of the language’s more advanced features, helping you expand your programming skills as she equips you with techniques you can use when building applications anywhere Java is used: in web, mobile, and desktop applications. Bethan covers a variety of topics, including generics, working with the Collections Framework, and functional programming. Plus, learn about I/O in Java, working with files and directories, and structuring applications using the modular system available in Java.

- [Instructor] Streams provide a clean and simple way to iterate over a collection in Java. Instead of using a forEach loop, streams allow functional programming techniques to be used. These streams are not to be confused with input and output streams which are something completely different. For example, this is a forEach loop, which iterates over a collection of books. If the author of the book's name begins with the letter J, then the two-string method of book is called and printed to the terminal. When I use a forEach loop like this in Java, it uses something called external iteration. What actually happens under the hood is an iterator object is created. The iterator object controls the iteration process. For each item in the collection, it checks if the book's author begins with J. If it does, it goes to the print statements. And if not, then it does nothing. Then it checks if there is a next item in the collection. If there is, then it calls the next method to move to the next…
