There is no such thing as a 2D array; what you have as an array of arrays.

tmp = new String[][]{{"word", "wordd", "worddd"}, {"wordddd", "worddddd"}}; maybe?

You may be able to obtain the contents for the array from a List.

There are bound to be other ways: anybody else?

You must fill the array either by row-wise or column-wise processing.

unfortunately i am unable to understand your question.
by the way in my opinion

1) when you create the object of an array and give the the size (ie 800 * 800 in your case) it is automatically initiazed with null at every index.
2) and second option is you just need one loop from index zero to 800 and fill up any string at all the indices.
