java - Iterate through multiple collections in the same "for" loop?

Question

I wonder if there's such a way to iterate thru multiple collections with the extended for each loop in java.

So something like:

for (Object element : collection1, collection2, ....)
         // do something ...

Thanks

You can do exactly this with Guava's Iterables.concat():

for (Foo element : Iterables.concat(collection1, collection2)) {
    foo.frob();
}
