Question

import java.text.DecimalFormat;

// Class representing a student

public class Student {

private String first; // first name

private String last; // last name

private double gpa; // grade point average

// Student class constructor

public Student(String first, String last, double gpa) {

this.first = first; // first name

this.last = last; // last name

this.gpa = gpa; // grade point average

}

public double getGPA() {

return gpa;

}

public String getLast() {

return last;

}

// Returns a String representation of the Student object, with the GPA formatted to one decimal

public String toString() {

DecimalFormat fmt = new DecimalFormat("#.0");

return first + " " + last + " " + "(GPA: " + fmt.format(gpa) + ")";

}

public class LabProgram {
public static void main(String args[]) {
Scanner scnr = new Scanner(System.in);
Course course = new Course();
int beforeCount;

// Example students for testing
course.addStudent(new Student("Henry", "Nguyen", 3.5));
course.addStudent(new Student("Brenda", "Stern", 2.0));
course.addStudent(new Student("Lynda", "Robison", 3.2));
course.addStudent(new Student("Sonya", "King", 3.9));

Student student = course.findStudentHighestGpa();
System.out.println("Top student: " + student);
}
}

Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in
the course. Assume that no two students have the same highest GPA.
Given classes:
• Class LabProgram contains the main method for testing the program.
• Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.)
• Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a
student's GPA.)
Note: For testing purposes, different student values will be used.
Ex. For the following students:
Henry Nguyen 3.5
Brenda Stern 2.0
Lynda Robison 3.2
Sonya King 3.9
the output is:
Top student: Sonya King (GPA: 3.9)

1 import java.util.ArrayList;

public Course() {
