Is there a way to create a collection of identical strings in java with one statement?

I want to create a queue of Strings that will have many identical elements in it (I'm simulating a set of program instructions). Is there any way to create this collection all at once with a single statement? 

myQueue.addAll(create collection of x strings);

Otherwise, I'll obviously have to loop x times and call myqueue.add(String) x times.

Just wondering if there is a one-line instead of 3-line way to do this...

Thanks!
