After "sorting" a 2D array, we can easily obtain the largest and the smallest elements of a 2D array. Let us look at the following analysis: Given 2D 273 367 680 654 51 135 151 432 492 502 293 358 65 612 412 681 465 765 265 150 593 647 54 665 Sarted roW 2D 273 654 135 432 492 150 593 65 151 293 680 465 612 367 681 647 765 665 358 51 54 265 412 502 Tranpose of 2D 358 593 654 680 681 51 54 150 273 293 367 65 135 465 647 151 432 612 765 265 412 492 502 665 Sorted row 2D again 65 135 293 367 51 150 273 465 647 54 265 412 492 612 358 593 654 680 681 765 151 432 502 665 You can see in the above display, we first sort each row of the 2D array; we then take the transpose of a two D array, i.e all the row elements becoming the column elements; we then sort each row of the 2D again. If you read the final array, each row is sorted; each column is also sorted. The smallest element obviously is the 1st element of the two D array an the last element is the largest element of a two D array. Let us now look at the following UML diagram: (Note that additional methods are allowed; proposed methods and instance variable cannot be changed)

TwoD class has only one instance variable which is a two D array of numbers ( int or double). The constructor must do some "deep" copying. A copy constructor. The other three methods are obvious in definition: to sort each row, to rotate the 2D array (i.e., change 1st row to 1st column, 2nd row to 2nd column etc.); and to display the 2D array (explore the use of nested enhanced for loops).
