Paul,
Paul Benedict said the following on 11/15/09 11:28:
I would like to propose adding this method:
/**
* Selects the object if not {...@code null}; otherwise fallsback to the
* specified default object.
*
* @param object the object to test
* @param defaultObject the default object
* @return the object if not {...@code null}; otherwise the default object
*/
public static Object defaultIfNull(Object object, Object defaultObject) {
return (object != null) ? object : defaultObject;
}
I don't get it. Why would anyone need the above when they can write:
obj != null ? obj : otherObj
themselves ??? Compared to
defaultIfNull(obj, otherObj)
you don't even save any keystrokes (and this is with a static import)!
