The tutorial show you many ways to convert an InputStream to String, including using Java 8 Stream.
Earlier in the tutorial Solution for find the N-th Fibonacci number, we have already known the methods that can be easily implemented with recursion and iteration. Today we will see a solution which demonstrates the power of recursion, and the iterative solution may not be a clearer method: Towers of Hanoi.

Regular expression (regex) defines patterns to recognise strings. Those patterns can be anything: a character, a specific string, a group of special characters or a combination of them. We can use Regular expression for searching, extracting, and modifying text.
This tutorial shows you an overview of Regular Expression Syntax.
Java supports a function: java.io.File.delete() to delete a File or an empty directory. But with non-empty folders, we need to implement function to delete them. In the tutorial, JavaSampleApproach will show you how to develop a recursive funtion to delete non-empty Folder.
