Assume you are given a boolean variable named isRectangular and a 2-dimensional array that has has been created and assigned to a2d. Write some statements that assign true to isRectangular if the entire 2-dimensional array is rectangular, meaning every row has the same number of elements as every other row.

CHALLENGE:

Assume you are given a boolean variable named isRectangular and a 2-dimensional array that has has been created and assigned to a2d. Write some statements that assign true to isRectangular if the entire 2-dimensional array is rectangular, meaning every row has the same number of elements as every other row.

SOLUTION:

isRectangular = true;
for (int i = 1; i < a2d.length && isRectangular; i++)
if (a2d[i].length != a2d[0].length)
isRectangular = false;
