Complete the Course class by implementing the courseSize() method, which returns the total number of students in the course.
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.
Ex. For the following students:
Henry Bendel 3.6 Johnny Min 2.9
the output is:
Course size: 2
public class LabProgram { public static void main (String [] args) { Course course = new Course(); // Example students for testing course.addStudent(new Student("Henry", "Bendel", 3.6)); course.addStudent(new Student("Johnny", "Min", 2.9)); System.out.println("Course size: " + course.courseSize()); } }
public class Student {
private String first; // first name private String last; // last name private…
Goal 1: Update the Fractions Class
Here we will overload two functions that will used by the Recipe class later:
multipliedBy, dividedBy
Previously, these functions took a Fraction object as a parameter. Now ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer (affecting numerator/denominator of the returned object). For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6.
Goal 2: Update the Recipe Class
The Recipe constructors so far did not specify how many servings the recipe is for. We will now add a private member variable of type int to denote the serving size and initialize it to 1. This means all recipes are initially constructed for a single serving. Update the overloaded extraction operator (<<) to include the serving size (see sample output below for an…

- Create a class called Planet. A planet's state is it's name and a list (array) of moons that it has. You can assume there is a Moon class that a single constructor that takes it's name as input (a String). Add three constructors to your Planet class: Planet(String planetName) (planet has no moons)Planet(String planetName, String moonName) (planet has one moon)Planet(String planetName, Moon[] moons) (planet has arbitrary number of moons). Be sure to use constructor chaining. Question: When creating a planet object, what is the minimum number of constructors that are called (in total, either explicitly by you or by the JVM)? What is the maximum number of constructors that might be called (in total, either explicitly by you or by the JVM)?

You are asked to write a java class named "Kume". The UML class diagram of the Kume class is as follows. 3 The elements in the set are kept in an ArrayList. The constructor of the class takes an array of int and adds the elements of this array to the ArrayList named al. The add() method adds an integer it takes as a parameter to the get element. The delete() method deletes an Integer object that it takes as a parameter from the get element, returns true if it can be deleted, otherwise false. The print() function prints the elements of the set to the console. The compareTo() method is inherited from the Object class and is suppressed, and compares the get element of the Set object, which it takes as a parameter, with the retrieve element of the current set object in terms of content (the order of the elements is not important). It returns 1 if both sets contain the same elements, 0 otherwise. Below is a test code that creates two objects from the Kume class and performs…arrow_forward

Each card is a Card object. Each Card object contains two instance variables ─ num andsuit. Study the Card class definition below for details.dealCard:This method removes the highest-indexed card in the ArrayList and returns it. In general, amethod should not do more than what it’s supposed to do.
