REpresentational State Transfer, or REST is an architectural standard for accessing and modifying resources on a server. These resources can be text, images, or data objects. REST APIs are used throughout the software industry to provide backend services to UIs or other services. Your project will use a REST API to manage the application data.

Before-Class Exercise

Setup the REST API build environment - individual
- Each team member will need to be able to build and execute a Maven-based Spring REST API project. You will likely be required to have access to maven and a specific (not necessarily the latest version) of Java, so before installing to be sure, CONFIRM THIS non-functional requirement with your instructor . These tools are setup on the machines in the SE labs or you can set them up on your own laptop referring to information on the resources page for installing Java and maven. If you are going to use your laptop, make sure to bring this to class.
  
  To demonstrate that you can run both of these tools, open a command or terminal window, and execute the following commands:
```
mvn --version
javac -version
java -version
```
  Note: If maven indicates that JAVA_HOME needs to be defined or later it can not find a Java compiler, you need to define the environment variable JAVA_HOME to point to the base of your installed JDK. On the SE lab machines, you can do this by selecting Start, type Accounts, User accounts -> Change my environment variables. You will have to find the latest JDK installed on the system. It will be either C:\Program Files\Java\jdk#.#.#_# or C:\Program Files (x86)\Java\jdk#.#.#_#. Set the JAVA_HOME environment variable to the proper directory.
- The development of your project will be done in the VS Code IDE. The REST API will be coded in Java. If you do not already have the Extension Pack for Java (by Microsoft) installed, go ahead and install it.
- Make a screen grab of the window showing the output generated by the mvn, javac, and jave commands and the VS Code Extension Pack for Java. Deposit these images in the myCourses Assignments folder, Setup the REST API build environment - individual, by the date specified on the schedule for your section.

In-Class Exercise

Build and run the sample REST API application - individual
- Your instructor will walk the entire class through the process of building and running the sample webapp from the command line. Your instructor will guide you through these instructions:
  - Download the Heroes REST API starter project and unzip to a directory of your choosing.
  - Open a terminal window (Command Prompt - Windows; Terminal - Mac) and navigate to the directory where you extracted the sample webapp files. This is the directory with the pom.xml file that describes how to build and execute the Heroes REST API.
  - Execute the command mvn compile exec:java which first builds the application and then starts the REST API running in a local jetty web server.
  - There should be no errors during the compile, and the last thing you see should be the a message indicating the the HeroesAPIApplication was started.
  - Open a web browser and navigate to http://localhost:8080/heroes/11. You should see the following in your browser window: {"id":11,"name":"Mr. Nice"} and the following in your terminal as the last line: GET /heroes/11
  - Take a screen capture of the command window showing the starting of the sample webapp. By the date specified on the schedule for your section, deposit the image in the myCourses Assignments folder, Build and run the Heroes REST API - individual.
- If time permits
