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 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 private fields: first name, last name, and GPA. (Hint: GetGPA() returns a student's GPA.) Ex: If the following students and their GPA values are added to a course: Henry Nguyen with 3.5 GPABrenda Stern with 2.0 GPALynda Robison with 3.2 GPASonya King with 3.9 GPA then the findHighestStudent() method returns a student and the program output is: Top student: Sonya King (GPA: 3.9)Code:Course.java: import java.util.ArrayList; //create class Student //create class Courseclass Courses{ private ArrayList<Student> roster; // collection of Student object // class constructor…

Add a private method simplify() to your Fraction class that converts a fraction to its simplest form. For example, the fraction 20 / 60 should be stored in the class instance variables as 1 / 3 (i.e. numerator = 1, denominator = 3). N.B.you will need a method to determine the Greatest Common Divisor (GCD.both of these methods (simplify and gcd) must be private. Asthese methods are private, client programs cannot access them. They can only be accessed within the Fraction class. Given their purpose, it would mean that any Fraction class method that modifies theinstance variables (e.g.: input, add, constructor, set) should call the simplify() method to reduce the instance variables to their minimum values. import java.util.ArrayList;import java.util.Scanner; class Fraction{private int n, d;public Fraction(){this.n = this.d = 0;}public Fraction(int n, int d){this.n = n;this.d = d;} public int getNum(){return n;}public int getDen(){return d;}public boolean isZero(){return(getNum() == 0…

Write a SelfPayKiosk class to support basic operations such as scan item, cancel transaction, checkout, and make payment. SelfPayKiosk.java is provided with method stubs. . Step 0. Declare private fields for number of customers served (int), total sales (double), and current amount due (double). Note the provided final variable for sales tax of 7%. Step 1 . Complete the constructor to initialize all private fields to zero. Complete the accessor methods to return the number of customers served, total sales, and current amount due. Step 2 . Complete the scanItem() method. Increase the amount due by parameter price. Do not update amount due if parameter price is negative. Step 3. Complete the checkOut() method. Multiply amount due by SALES_TAX and add to amount due. Step 4. Complete the makePayment() method. If parameter payment is enough to pay the amount due, increase total sales by amount due, increment number of customers served, and reset amount due to zero in preparation for…
