Description
This lab provides you with exposure to Exceptions and Exception Handling when developing with the Java programming language. You will be required to complete the following guided coding exercises:
- Exercise 1 - Exceptions: Implement exception handling for resource management using a try-catch-block statement
- Exercise 2 - Exceptional: Implement a subclassed Exception class for customized exception handling
Note: Each exercise comes with the fully completed solution code when required or assistance is needed.
Lab Objectives
Upon completion of this lab, you will be able to:
- Write Java code that can handle runtime exceptions gracefully
- Create customized Exception-based classes
You should:
- Be comfortable with using a browser-based IDE
Lab Environment
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 2 lab exercises:
- Exercise 1 - Exceptions
- Exercise 2 - Exceptional
Updates
June 16th, 2018 - Optimized creation of lab resources to reduce the time it takes to access the browser IDE by 60%.
