Oracle JDK: The Commercial Option
Oracle JDK is another widely used distribution, but it comes with different licensing terms:
- Free for Development: You can freely use Oracle JDK for development and testing purposes without any charge.
- Subscription Required for Production: If you plan to use Oracle JDK in a production environment, a commercial subscription is required for updates and support.
- Regular Support: With a subscription, you gain access to regular updates and support from Oracle, which is beneficial for enterprise-level applications.
