+# Spring Boot REST API Exercise
+
+## Goal
+
+The goal of this exercise is to learn how to use GitHub Copilot, using an exercise that consist of building a REST API using Spring Boot.
+
+## Exercises
+
+We have created a Spring Boot project with some files already created, you can find the project in the folder **exercisefiles/springboot**. 
+
+Let's start copiloting!!!
+
+### 1. Create the code to handle a simple GET request
+
+Move to the 'DemoController.java' file and start writing the code to handle a simple GET request. In this first exercise, we have provided a comment that describes the code you need to generate. Just press enter and wait a couple of seconds, Copilot will generate the code for you.
+
+There is already a unit test implemented for this exercise, you can run it using the command `mvn test` before and after to validate that the code generated by Copilot is correct.
+
+Then, create a new unit test for the case when no key is provided in the request.
+
+After every exercise, feel free to package and run your application to test it.
+
+Package: `mvn package`
+
+Run: `mvn spring-boot:run`
+
+Test: `curl -v http://localhost:8080/hello?key=world`
+
+### 2. Dates comparison
+
+New operation under /diffdates that calculates the difference between two dates. The operation should receive two dates as parameter in format dd-MM-yyyy and return the difference in days. 
+
+Additionally, create a unit test that validates the operation.
+
+From now on, you will have to create the unit tests for every new operation. Wasn't it easy with Copilot? 
+
+### 3. Validate the format of a spanish phone 
+
+Validate the format of a spanish phone number (+34 prefix, then 9 digits, starting with 6, 7 or 9). The operation should receive a phone number as parameter and return true if the format is correct, false otherwise. 
+
+### 4. Validate the format of a spanish DNI
+
+Validate the format of a spanish DNI (8 digits and 1 letter). The operation should receive a DNI as parameter and return true if the format is correct, false otherwise. 
+
+### 5. From color name to hexadecimal code
+
+Based on existing colors.json file under resources, given the name of the color as path parameter, return the hexadecimal code. If the color is not found, return 404
+
+Hint: Use TDD. Start by creating the unit test and then implement the code.
+
+### 6. Jokes creator
+
+Create a new operation that call the API https://api.chucknorris.io/jokes/random and return the joke.
+
+### 7. URL parsing
+
+Given a url as query parameter, parse it and return the protocol, host, port, path and query parameters. The response should be in Json format.
+
+### 8. List files and folders 
+
+List files and folders under a given path. The path should be a query parameter. The response should be in Json format.
+
+### 9. Word counting
+
+Given the path of a file and count the number of occurrence of a provided word. The path and the word should be query parameters. The response should be in Json format.
+
+### 10. Zipping
+
+Create a zip file with the content of a given folder. The path of the folder should be a query parameter.
+
+### 11. Containerize the application
+
+Use the Dockerfile provided to create a docker image of the application. There are some comments in the Dockerfile that will help you to complete the exercise. 
+
+In order to build, run and test the docker image, you can use Copilot as well to generate the commands. 
+
+For instance, create a DOCKER.md file where you can store the commands to build, run and test the docker image. You will notice that Copilot will also help you to document your project and commands. 
+
+Examples of steps to document: Build the container image, Run the container, Test the container.
