Question

What settings and commands does one need to perform to make comments like this in emacs:

  /**
   * 
   * something here
   */

Thanks.

Answer 1

An easy way is to define your own command for inserting this
comment. Add this to your .emacs file:

(defun insert-doc-comment () (interactive)
   (insert "/**\n * Brief description. Long description. \n * @param \n * @return \n * @exception \n * @see \n * @author \n */"))

Then bind the new command to a key of your liking:

(define-key global-map [(S-f1)] 'insert-doc-comment)

Now pressing Shift-F1 will insert a comment block like this:

/**
 * Brief description. Long description. 
 * @param 
 * @return 
 * @exception 
 * @see 
 * @author 
 */
