This lab is to test your understanding of a Pairs project and sorting method discussed during last week's lectures. The sorting method from the lectures used an array with a type parameter. Given the following Pairable Interface, ComparablePair class, and Tester class, implement a sort method in the Test class that sorts ComparablePair objects. public interface Pairable { public T get First (); public T getSecond(); } public class ComparablePair implements Pairable , Comparable { private T first; private T second; public ComparablePair (T firstItem, T secondItem) { first firstItem; second secondItem; } @Override public T getFirst () { return first; } @Override public T get Second () { return second; } @Override public String toString () { return "(" + first + ", } + second + ")"; @Override public int compareTo (ComparablePair 0) { int first Comparison = this.getFirst().compareTo (o.getFirst()); int secondComparison = this.getSecond ().compareTo (o.getSecond ()); return first Comparison != 0 ? first Comparison secondComparison; import java.util.ArrayList; public class Tester { public static void main (String[] args) { ArrayList listOfStringPairs = new ArrayList (); listOfStringPairs.add (new ComparablePair ("Irene Johnson", "Sandra James")); listOfStringPairs.add(new ComparablePair ("Janet Brown", "Jose Richardson")); listOfString Pairs.add(new ComparablePair ("Norma Powell", "Russell Ramirez")); listofString Pairs.add(new ComparablePair ("Walter Bell", "Kelly Phillips")); listOfStringPairs.add(new ComparablePair ("Norma Powell", "Joe White")); sort (listOfStringPairs); for (ComparablePair stringPair listOfString Pairs) { System.out.println (stringPair); } } // Implement a sort method. public static void sort ( // Your code here. } ) { This lab is to test your understanding of a Pairs project and sorting method discussed during last week's lectures.
