Whenever possible I use official Docker images to run applications, services, and tools so I don’t have to install and maintain a myriad of different applications on my development machine. The Apache HTTP server benchmarking tool ab is a handy utility you can use to quickly performance test your HTTP services.

Value types and how to implement them in Java is introduced early in the book and for good reason. value types are great for increasing type safety and getting the compiler to detect errors for you while you write code.
