How To Use the Google Translate API with Java | RapidAPIIn this tutorial, we use the Google Translate API (version two) on RapidAPI using a Java command-line client. We program the client as a Spring Boot application and use three different Java REST libraries – the Eclipse Jersey implementation of the Java API for RESTful Web Services (JAX-RS), the Unirest-Java library, and the OkHttp library. Of course, our application is a wrapper around the Google Translate API, so it might be more proper to state that we are creating a use-case diagram of a user’s interactions with the Google Translate API. The diagram is especially useful when we first start coding our application, as we can create a bare-bones skeleton of our application derived from this model which we will then add functionality (functionality derived from the use-case model). As this is a relatively simple application, we can now model our class diagram as three classes that extend the abstract TutorialRestClient class.
