Variable names by convention begin with a lower-case letter and use
camelCase
for the rest.
You named this variable an array, but didn't declare it as one. This
statement will never compile.

Array notation uses square brackets, not parentheses. As written, your
statement will not compile.

Why? It's perfectly sensible and quite useful.

Not at all. Since Java doesn't sup****t two-dimensional arrays, it makes
perfect sense. String [] [] doesn't declare an array of Strings, it
declares
an array of String [].

Nope. And there's absolutely nothing "magical" about grabbing rows - you
actually aren't grabbing rows, you are grabbing array elements.
