This lab introduces you to JShell, an interactive REPL Java utility. You will be required to complete the following guided coding exercises:
- Exercise 1 - Starting and Stopping: Learn how to start and stop JShell
- Exercise 2 - Feedback Modes: Learn how to configure different feedback modes to help with your interaction with JShell
- Exercise 3 - Snippets: Declare and use Java statements, variables, methods, expressions, and class definitions
- Exercise 4 - Commands: Learn to use the various JShell commands to control the session
Upon completion of this lab, you will be able to:
- Confidently use the JShell for exploratory Java coding and prototyping
- Be comfortable with using a browser-based IDE
- Be comfortable with using the integrated terminal
This lab will start with the following AWS resources provisioned automatically for you:
- A single EC2 instance, named ide.java.platform.instance, which will have a public IP address attached. This instance will host a web-based Java IDE (based on the Visual Code editor).
To achieve the lab end state, you will be walked through the process of:
- Using your local browser, access the web-based Java IDE served from the ide.java.platform.instance
- Completing the 4 lab exercises:
- Exercise 1 - Starting and Stopping
- Exercise 2 - Feedback Modes
- Exercise 3 - Snippets
- Exercise 4 - Commands
June 16th, 2018 - Optimized creation of lab resources to reduce the time it takes to access the browser IDE by 60%.
