How do you store 2D arrays in Java?

2D Arrays Many programming languages actually storetwo-dimensional array data in a one-dimensional array. The typical way to do this is to store all the data for the first row followed by all the data for the second row and so on. This is calledrow-majororder.

How many subscripts do I need for a two-dimensional array?

A reference to an individual element of a two-dimensional array requires two subscripts. By convention, programmers use the first subscript for the rows, and the second for the columns. Each subscript must be bracketed individually.
