Thus the array orange would represent an array with three rows numbered 0, 1, and 2 and four columns 0, 1, 2 and 3. Thus the variable in the 1st row (numbering from 0) and 2nd column (numbering from 0) would be orange[1][2]. 2-D arrays, just like 1-D arrays, can be big or small: Here’s a small array: int [ ][ ] apple = new int[2][3];
