First, one can obtain the list of supported currencies, this can be accomplished by navigating the following URL https://openexchangerates.org/a...

Here is a link to my Getting Started with Dropwizard course on Udemy. Only $10! Dropwizard is a bunch of superb frameworks glued together to provide a fast way of building web applications including REST APIs. We'll talk about great frameworks which are parts of Dropwizard as we go over our examples. The full code for the examples can be obtained here . The simplest way to create a Dropwizard project is to use the Maven archetype called java-simple which is a part of Dropwizard. This can be accomplished either via the command line or using your favorite IDE. Let's stick to the former approach.
