Java API /JavaCS2/src/comparables/Person.java /JavaCS2/src/comparables/Student.java /JavaCS2/src/comparables/Employee.java Suppose we want to alter the Person class so that it implements the Comparable interface. The class declaration now includes the interface Comparable as follows: public class Person implements Comparable Provide a body for the compareTo method in the space below, so that person A is considered less than person B if the age of person A age is less than the age of person B. Also, person A should be equal to person B if their ages are equal. /** * Compares this object with the specified object for order. * @param o the Object to be compared. */ public int compareTo(Object obj) { // Insert code here }
