Modify the LinkedList1 class presented in this chapter by adding sort() and reverse() methods. The reverse method reverses the order of the elements in the list, and the sort method rearranges the elements in the list so they are sorted in alphabetical order. The class should use recursion to implement the sort and reverse operations. Extend the graphical interface in the LinkedList1 Demo class to support sort and reverse commands, and use it to test the new methods.
