How do you add Apache Derby nature to a Java project on eclipse. Instruction says that I should right click on the project directory and Select APACHE derby menu. But I do not fine any such menu?

If you don't see the Apache Derby menu when right-clicking your project in Eclipse, make sure that the Apache Derby plugin is correctly installed. You can install it by going to Help > Eclipse Marketplace, searching for "Apache Derby," and following the installation prompts. Once installed, you may need to restart Eclipse. After that, right-click on your project, and you should be able to find the Apache Derby options.
