To learn java language programming, you must choose a powerful, easy-to-use IDE that can assist programming.
Eclipse is currently the most popular Java language development tool. Its powerful code assistance function can help developers automatically complete coding tasks such as grammar correction, text completion, code repair, API prompts, etc., saving a lot of time required for program development.
This tutorial uses Eclipse as the development tool, and its installation is described below.
