---

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.

Objectives

Interactive Java & JShell: Writing Java Programs with the Interactive JShell discover the key concepts covered in this course set up JShell and execute basic Java commands in the interactive environment create and invoke functions in the JShell define a function that includes a forward reference and recognize the limitations of such methods adjust feedback modes to regulate the output produced after running code snippets use the auto-complete feature to automatically fill in code details recognize how imports work in JShell and how objects can be instantiated create and use classes or types in JShell in order to work with bespoke entities describe how objects are affected when the classes they are built out of are modified read in data from a CSV file into a JShell program export and save data in your program out to a file gather together snippets of previously executed code to create a JShell script summarize the key concepts covered in this course
