Chapter 12, Problem 1P

Revise the method selectionSort within the class ArraySorter, as shown in Listing 7.10 of Chapter 7, so that it sorts the strings in an instance of the class ArrayList<String> into lexicographic order instead of sorting the integers in an array into ascending order. For words, lexicographic order reduces to alphabetic order if all the words are in either lowercase or uppercase letters. You can compare two strings to see which is lexicographically first by using the String method compareTo, as described in Figure 2.5 of Chapter 2.
