How to use Google Translate API in Java

The tutorial comprehensively guides developers on integrating the Google Translate API (version two) into a Java command-line client using RapidAPI. It demonstrates how to interact with the API's three endpoints—languages, detect, and translate—via three Java REST libraries: JAX-RS, Unirest-Java, and OkHttp, within a Spring Boot application. The process involves modeling the application using UML, setting up the project with Spring Initializr, and implementing JSON data objects for seamless integration. Developers are shown how to configure their applications to make RESTful API calls, handle JSON responses, and manage headers using different libraries. The tutorial emphasizes the importance of preliminary modeling and provides a detailed walkthrough of setting up and utilizing each library to access Google Translate endpoints, ultimately offering insights into effectively incorporating the Google Translate API into Java applications.
