As this book presents many web services and RESTful services concepts, there are no specific requirements for you to follow; however, if you want to run and execute the code samples provided in the book (which you should), then you need a basic understanding of Java programming languages, Maven, or knowledge of any build tools.

The chapters with sample code have clear explanations of how to run and test the samples, and come with the build and run scripts as well.

You can download the example code files for this book from your account at www.packtpub.com. If you purchased this book elsewhere, you can visit www.packtpub.com/support and register to have the files emailed directly to you.

You can download the code files by following these steps:

1. Log in or register at www.packtpub.com.
2. Select the SUPPORT tab.
3. Click on Code Downloads & Errata.
4. Enter the name of the book in the Search box and follow the onscreen instructions.

The code bundle for the book is also hosted on GitHub at https://github.com/PacktPublishing/Hands-On-RESTful-API-Design-Patterns-and-Best-Practices. In case there's an update to the code, it will be updated on the existing GitHub repository.

We also have other code bundles from our rich catalog of books and videos available at https://github.com/PacktPublishing/. Check them out!

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "The four basic HTTP operations: GET, POST, PUT, and DELETE."

A block of code is set as follows:

@GetMapping({"/v1/investors","/v1.1/investors","/v2/investors"})
  public List<Investor> fetchAllInvestors()
    {
       return investorService.fetchAllInvestors();
    }

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

public interface DeleteServiceFacade {
    boolean deleteAStock(String investorId, String stockTobeDeletedSymbol);
    boolean deleteStocksInBulk(String investorId, List<String> stocksSymbolsList);
}

Any command-line input or output is written as follows:

$ mkdir css
$ cd css

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "The Pipeline entity is entirely responsible for orchestrating control and data flows"
