Expert Answer

 1) Following is the required program for above mentioned problem. The code’s been compiled and run in Eclipse IDE and is a genuine piece of work.

The code BEGINS from here:

* Class Name
public class Name {
private String first;
private String last;

// Constructor
public Name(String fName, String lName){
first = fName;
last = lName;

// toString Method
public String toString(){
return (first + ” ” + last);


* Student Class

public class Student {
public Name name;
private double gpa;

// Constructor
public Student(String fName, String lName, double gp){
name = new Name(fName, lName);
gpa = gp;

// updateGPA Method
public void updateGPA(double gp){
    // Your code to change the gpa here

// toString Method
public String toString(){
return (name.toString() + “: ” + gpa);

**************** DemoClass.java*********************

public class DemoClass {
public static void main(String[] args) {
Student stu = new Student(“Shadow”, “Blade”, 9.5);

Note: The main class is just for a demo.
