In Eclipse, is there a way to run the Javadoc tool against my code?

The answer is yes! While I knew this was possible, I wasn’t exactly sure of how this is done. It turns out using Javadoc from within Eclipse is a piece of cake. Given your Eclipse IDE is already configured to use the tools from a JDK, chances are good that it is already setup to generate Javadocs for your code with a simple menu selection. In Eclipse, look for the Project menu option on the Eclipse menu bar. Select Generate Javadoc… from the Project pull-down menu.



This should cause the Generate Javadoc window to open where you can specify what members should be included (private up to public) and where the documents generated should be put. If the JDK’s bin folder and/or the javadoc.exe tool can’t be found, the same window allows you to point Eclipse to a valid Javadoc generating tool and configure it per your needs.



Once the Javadocs are created, the documents are used by Eclipse to produce hovers over the classes, methods, variables, etc.
