I'm confused as to the purpose of three javadoc comments.
Code:
/**
 * What's this for?
 */

package group.subgroup

import some.stuff;
import some.extra.stuff;

/**
 * And this one?
 */

public class Foo {
    
    /**
     * Finally, this one?
     */
    
    //methods and their comments (i get how those work)...
}
And where do things like author, version, date, and copyright go?
