Modify the Student class presented below as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on the parameter values. Overload the constructor such that each test score is assumed to be initially zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the appropriate score. Also provide a method a called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods. public class StudentBody { public static void main (String [] args ) { Address school = new Address ("800 Lancaster ave.", "Villanova", "PA", 19085); Address jHome = new Address ("21 Jump Street", "Lynchburg", "VA", 24551); Student john = new Student ("John", "Smith",jHome, school); Address mHome = new Address ("123 Main Street", "Euclid", "OH",44123); Student marsha = new Student ("Marsha", "Jones", mHome, school); System.out.println (john); System.out.println (); System.out.println (marsha); } } class Student { private String firstName, lastName; private Address homeAddress, schoolAddress; public Student (String first, String last, Address home, Address school) { firstName = first; lastName = last; homeAddress = home; schoolAddress = school; } public String toString () { String result; result = firstName + " " + lastName + "\n"; result += "Home Address: \n" + homeAddress + "\n"; result += "School Address: \n" + schoolAddress; return result; } } class Address { private String streetAddress, city, state; private long zipCode; public Address (String street, String town, String st, long zip) { streetAddress = street; city = town; state = town; state = st; zipCode = zip; } public String toString () { String result; result = streetAddress + "\n"; result += city + ", " + state + " " + zipCode; return result; } }...
