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%.
