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…

Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.2 GPABrenda Stern with 1.2 GPALynda Robison with 3.3 GPAJake Flynn with 1.8 GPA then the countProbation() method returns 2 and the program output is: Probation count: 2 Course.java import java.util.ArrayList; public class Course { private ArrayList<Student> roster; // Collection of Student…
This program is going to maintain a list of customers’ names and bank account balances. 1. Create a class called CustomerList with a main method that instantiates an ArrayList of String objects called customerName. Invoke the add method to add the following names into the ArrayList: Cathy Ben Jorge Wanda Freddie 1. Print each name in the ArrayList using a for a loop. 2. Create another ArrayList object called customerBalance, to save users’ balance. What is the type of this ArrayList? double or Double? You just need to declare this ArrayList and leave it empty for now. 3. For each customer, print the name and ask the user to enter the initial balance for this customer. Save the initial balance into ArrayList customerBalance. Use a loop to get this done for all 5 customers. The program should print out this for the first customer: Example: Please enter the account balance for Cathy: (waiting for user’s input …) Code: for(int i=0; i<5;i++) { Print(“Please enter the account balance…
IN JAVA LANGUAGE Write an ATM class with an ArrayList of Account objects as an attribute. In the constructor, add 3 Account objects to your ArrayList. They can all have a start balance of $100 and an annual interest rate of 0.12. Include two methods, menu and makeSelection as outlined below. Please note that since both methods get user input, create a Scanner attribute to use in both. menu method This method does not have any parameters and does not return a value. It should: Get the account number from the user. This corresponds to the index of the items in the ArrayList. Since there are 3 elements in your ArrayList, you are going to ask them for a number between 1 and 3, but keep in mind that the indices of the ArrayList are 0-2, so you'll have to adjust the value you get from the user accordingly. Present the user with a main menu as shown below: Get their menu selection Call the makeSelection method, passing it the account index obtained in step 1 and the menu selection…
Use NetBeans Note for all the above User-Defined Classes: • Provide appropriate validation code so the right values get populated in the instance variables. For example, the payrate should not be negative. Write a Java application (Client) program with a static method called generateEmployees( ) that returns a random list of 10 different types of Employee objects. You would use an ArrayList to store the employee objects that will be returned. Use a for loop to populate randomly different types of employee objects with some random data. You could possibly think of a range of values like 1 – 4. If random value is 1, create a HourlyEmployee object with some randomly generated data, if 2, a SalariedEmployee object with some random data and so on. I would leave it to your ingenuity to generate and populate these different Employee objects with other data like name etc. As these objects are generated, add them to your data structure (array or ArrayList that you are using). Finally, the…

Through java, have The Delicious class – fields and constructor The class must define and initialise a field of an appropriate collection class to store Chicken objects. There must be no pre-defined limit on the number of Chiciken objects it can store.The Delicious class – basic methodsThe Delicious class must:• Define a method called addChicken that takes a Chicken object as a parameter and adds it to the ArrayList field. Note that this method must not create a Chicken object. Instead, a Chicken object must be passed into it as a parameter value.• Define a method called getNumberOfChickens that returns the number of Chicken objects in the ArrayList.• Define another method also called getNumberOfChickens. This one takes a single parameter of type int representing a price per Kilogram and returns the number of Chicken objects in the collection whose pricePerKilo is less than or equal to the value of the parameter.• Define a method called list that prints out, via System.out, the details…

you created a Card class that represents a standard playing card. Use this to design and implement a class called DeckOfCards that stores 52 objects of the Card class using an array. Include methods to shuffle the deck, deal a card, return the number of cards left in the deck, and a toString to show the contents of the deck. The shuffle methods should assume a full deck.Create a separate driver class that first outputs the populated deck to prove it is complete, shuffles the deck, and then deals each card from a shuffled deck, displaying each card as it is dealt along with the number of cards left in the deck. This is my Card class: mport java.util.Random; /*Card.java Richard Mino * This is a program demonstrating the use of random and predetermined objects and values in the form * of a playing card using getter/setter methods and two constructors and printing them out as a string * using the toString method */public class Card { //Set up variables for card rank and…
