Most Java developers use a full-fledged IDE to build complex Java applications. However, there will be many occasions where you need to test snippets of Java code quickly or build a small script without the overhead of having to develop, compile, and execute programs. This is where JShell comes in. In this course, practice using JShell to run snippets of Java code and get immediate results. Use various features of JShell, from the declaration of functions, available feedback modes, and the auto-complete feature. Define a class in various iterations until you're satisfied with its behavior. Then, compile several snippets of previously run Java code to build a JShell script that reads data from one file, transforms it, and writes it into another file. When you're done with this course, you'll be able to use JShell to write your Java programs.
