I wanna declare 2-dimensional deque in JAVA.
So, in c++ I did deque<deque<string>> table to initialize 2 dimensional deque. Could you please let me know how to declare 2dimensional deque in JAVA?

You would do,ArrayDeque<ArrayDeque> myTwoDimensionDeque = new ArrayDeque<> ();(read about generics in Java)

Don't fall into the trap of trying to write (or learn) Java by using C++ as a model. Learn Java as Java.

Possible duplicate of Creating an array of Deques, which gives you a solution close to what you were asking for, but don't think of it as being 2-dimensional in the sense of arrays; the accepted answer gives you a list of Deques.

@MehdiB. That approach gives a single ArrayDeque which contains ArrayDeque elements. Access to the nth ArrayDeque element would only be possible using iteration (apart from the first and last entries). Since the question is tagged with multidimensional-array it is fair to assume that the OP wants to be able to access ArrayDeque element n directly.
