Breaking a long URL to several line in javadoc

Question

If I'm using a piece of code or resources fetch from etc internet I like to point this out in class or function documentation and also provide a link to the original source. However, I would also like to stick to max 80 chars per line principle when writing code for better readability. Is there a way to parse a long URL in source to multiple lines and still maintain the original address as usable when using the javadoc in IDE like Eclipse? And with usable I mean that clicking the URL in javadoc tooltip opens the correct page.

For example, how would you format the following:

/**
 * Class to do some cool stuff
 * Original source: 
 * http://stackoverflow.com/questions/and-huge-amouts-of-URL-address-which-does-not-fit-to-80-chars
 */
public class ExampleClass {

}

Answer 1

If you don't want to use a URL shortener you can surround your url with <pre></pre> tags as follows:

/**
 * Class to do some cool stuff
 * Original source: 
 * <pre>
 * See <a href="http://stackoverflow.com/questions/
   and-huge-amouts-of-URL-address-which-does-not-fit-to-80-chars">NameOfyourLink</a>
 * </pre>
 */

This will satisfy checkstyle for example and let you keep your original URL.

Answer 2

Another solution I found is to just break the lines and make sure the successive ones follow exactly the URL (not have any other character in between).

For example:

/**
* Link to <a href="https://developer.android.com/reference/android/app/Service#
startForeground(int,%20android.app.Notification)">startForeground(..)</a>
