If
you import external libraries to your Eclipse, now you need to import JavaDoc for the description of Methods and Class of the external libraries. If you have the JavaDoc in your Eclipse, if you place the cursor on a method of the external library, you can read an explanation of the method.
To import it, you need to download JavaDoc for the library from somewhere. Once downloading it, you open your Eclipse. Open your project explorer and right-click on a name of project to which you want to import the JavaDoc.
Then choose "JavaDoc Location" then "Browse".
And choose the file of the JavaDoc.
