There is only one action, the 'ToggleComment' action.

>>
if (isSelectionCommented(selection))
	operationCode= ITextOperationTarget.STRIP_PREFIX; //uncomment
else
	operationCode= ITextOperationTarget.PREFIX; //comment


Take a look at this class
org.eclipse.jdt.internal.ui.javaeditor.ToggleCommentAction
