Read the original article Hit count: 168

On my previous job, providing all methods with javadoc was mandatory, which resulted in things like this:

/**
 * Sets the Frobber.
 *
 * @param frobber The frobber
 */
public setFrobber(Frobber frobber) { ... }

As you can see, the documentation adds little to the code, but takes up space and work.

Should documenting all methods be mandatory or optional? Is there a rule for which methods to document? What are pros and cons of requiring every method to be documented?
