Is there a varargs null check function in Java or Apache Commons?

I've got four variables and I want to check if any one of them is null. I can do

if (null == a || null == b || null == c || null == d) {
    ...
}

but what I really want is

if (anyNull(a, b, c, d)) {
    ...
}

but I don't want to write it myself. Does this function exist in any common Java library? I checked Commons Lang and didn't see it. It should use varargs to take any number of arguments.

From stackoverflow

• I don't know if it's in commons, but it takes about ten seconds to write:

  public static boolean anyNull(Object... objs) {
      for (Object obj : objs)
          if (obj == null)
              return true;
      return false;
  }
  

  Steven Huwig : Yeah I know but then the question is where to put it. ;)

  Michael Myers : Do you have a utilities class of some sort? It seems like I always end up with one.

  Steven Huwig : Yeah, it's Commons Lang, Commons IO, Commons Collections, etc...

  Michael Myers : Well, I just did some scouting around and found a couple of anyNull methods, but they seem to predate varargs.

  OscarRyz : nice question and nice answer

  Michael Myers : I tried searching Google Code (http://code.google.com/), but I'm not exactly sure how to formulate the search. The basic structure of the code would look something like this, but the names could be almost anything.

  Steven Huwig : Makes me wish for Hoogle: http://www.haskell.org/hoogle/

  Michael Myers : Interesting. That would indeed be useful. Joogle? Javoogle? Anyone?

• The best you can do with the Java library is, I think:

  if (asList(a, b, c, d).contains(null)) {
  

  Michael Myers : With a static import of java.util.Arrays.asList, I presume?

  Tom Hawtin - tackline : Yes. You have to import it someway. Although it is a bit of a cheat...

  OscarRyz : close to literate programming

  Michael Myers : A little slower, too, one would guess, but no external libraries and no figuring out where to put the anyNull method.

• You asked in the comments where to put the static helper, I suggest

  public class All {
      public static final boolean notNull(Object... all) { ... }
  }
  

  and then use the qualified name for call, such as

  assert All.notNull(a, b, c, d);
  

  Same can then be done with a class Any and methods like isNull.

  Steven Huwig : I like that idea very much.
