2. Add a constructor to populate the array in the class using Java
random number generator, and a
setter/getter for the array, and toString().
The array length is passed to the constructor.
(3
points)
3. Add the following methods to the class and use them in the main
method: (5 points)

value given in “item”.
b. pickMaxIndex(arr, start, end) that returns the

c. Swap(arr, index-i, index-j) that swaps the value
in index I with the value in
index j.
d. selectionSort() that sorts the array in descending

4. Popular a two-dimension array from an input file of 5 rows and
10 columns, sort each row and

points)
5. Create a main method to print the
integer array after sorted using for-each state without using
indexes. (5 points)
Bonus: (5 points)
6. Create a swap method without temporary variable.
