If you need a full-featured Java IDE with enterprise development tools and a free trial, IntelliJ IDEA is definitely worth a look. It's a full-featured IDE that supports multiple languages and frameworks, including Spring and Jakarta EE, and has advanced code editing, run and debug tools, and built-in database tools. It also supports cloud deployment and management, which is useful for enterprise applications. It's a subscription-based product, but you can try it out with a free trial to get a better idea of what it can do.
Another contender is Genuitec, which offers a collection of tools for enterprise development, including MyEclipse, a full-featured Java IDE with a 30-day free trial. MyEclipse has rich framework support, live reload and database support. It also has tools like Eclipse Plugin Manager for secure software distribution and CodeMix for advanced modern web development, so it can handle a variety of enterprise development needs with different pricing options.
For a more modern take on code editors, Zed offers a high-performance, multiplayer code editor that combines the power of an IDE with the snappiness of a lightweight editor. It supports AI-powered code generation and an integrated terminal, along with advanced collaboration abilities. A free trial is available, so you can try it out before you buy.
