Lab Overview

Being able to code productively with Java Collections is an essential skill needed to create robust, bug-free, and performant applications.

This lab is designed to deepen your Java Collections knowledge. You will be required to complete the following Java coding exercise:

• Exercise 1 - Comparators: Complete the Comparator code required to implement a custom sorting algorithm used to order a deck of cards
• Exercise 2 - SimpleGame: Complete the Collection code required to implement a simple interactive console-based card game
• Exercise 3 - UsingCollections: Complete the collection based code required to read in a Movie dataset stored on the filesystem and implement various querying capabilities exposed as a service

Note: Each exercise is supplied with a fully completed solution code for reference when required.

Lab Objectives

Upon completion of this lab, you will be able to:

• Be able to work confidently with Java Collections
• Implement custom sorting algorithms using Comparators
• Understand the benefits of working with Java Collections and associated Interfaces
• Run and debug the Java code and examine the results that are printed to the console

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 following lab exercises:
  
  • Exercise 1 - Comparators
  • Exercise 2 - SimpleGame
  • Exercise 3 - UsingCollections

Updates

June 16th, 2018 - Optimized creation of lab resources to reduce the time it takes to access the browser IDE by 60%.
