Create a class named Billing that includes three overloaded computeBill()methods for a photo book store. When computeBill() receives a single parameter, it represents the price of one photo book ordered. Add 8% tax, and return the total due. When computeBill() receives two parameters, they represent the price of a photo book and the quantity ordered. Multiply the two values, add 8% tax, and return the total due. When computeBill() receives three parameters, they represent the price of a photo book, the quantity ordered, and a coupon value. Multiply the quantity and price, reduce the result by the coupon value, and then add 8% tax and return the total due. Write a main() method that tests all three overloaded methods please write the code in java

Create a class with the name 'QuadraticSolver'.The two roots of a quadratic equation of the form ??2 + ?? + ? = 0 can be obtained using the quadratic equation formula ?2 − 4?? is called the discriminant of the quadratic equation. If it is positive, the equation has two real roots. If it is zero, the equation has one root. If it is negative, the equation has no real roots. In the QuadraticSolver main method, write a program that prompts the user to enter values for a, b, and c and displays the result based on the discriminant. If the discriminant is positive, display the two roots. If the discriminant is 0, display one root. Otherwise, display the imaginary roots. Note that you can use Math.pow(x, 0.5) to compute √?. Here are three separate sample runs: 1.0, 3, 1The equation has two roots: -0.38 and -2.62 1, 2.0, 1The equation has one root: -1.00 1, -4, 8The equation has two imaginary roots: 2.00 + 2.00i and 2.00 - 2.00i
Create a class named Pay that includes five double variables that hold hours worked, rate of pay per hour, withholding rate, gross pay, and net pay. Create three overloaded computeNetPay() methods. When computeNetPay() receives values for hours, pay rate, and withholding rate, it computes the gross pay and reduces it by the appropriate withholding amount to produce the net pay. (Gross pay is computed as hours worked multiplied by pay per hour.) When computeNetPay() receives two parameters, they represent the hours and pay rate, and the withholding rate is assumed to be 15%. When computeNetPay() receives one parameter, it represents the number of hours worked, the withholding rate is assumed to be 15%, and the hourly rate is assumed to be 5.85. Write a main() method that tests all three overloaded methods. Save the application as Pay.java.
I need to write a jave program to keep track of a team sport. Write a class, Team.java, that has the following: * two private instance variables: a String named color and an int named score. * a default constructor with no parameters that initializes color to "Red" and score to zero. * a constructor that takes two parameters (one for each instance variable) and sets the values of the instance variables. * a public getter and setter method for each instance variable. * a toString method that returns the color and score in the following format: "Red Team with 0 points."
Build a class called BankAccount that manages checking and savings accounts. The class has three private member fields: a customer name (String), the customer's savings account balance (double), and the customer's checking account balance (double). Implement the following Constructor and instance methods: public BankAccount(String newName, double amt1, double amt2) - set the customer name to parameter newName, set the checking account balance to parameter amt1 and set the savings account balance to parameter amt2. (amt stands for amount)public void setName(String newName) - set the customer namepublic String getName() - return the customer namepublic void setChecking(double amt) - set the checking account balance to parameter amtpublic double getChecking() - return the checking account balancepublic void setSavings(double amt) - set the savings account balance to parameter amtpublic double getSavings() - return the savings account balancepublic void depositChecking(double amt) - add…
Write a Java class called HotelRoom that represents a hotel room. The class will contain the following attributes: •RoomNo (int) •PhoneNumber (string) •Capacity (int) – Number of people that room can accommodate. •Grade (int) – Grade of room ranging 1-5, 5 being most valuable. Your class should have a constructor that takes a single parameter: RoomNo. The necessary accessors (i.e. get methods) and mutators (i.e. set methods) for class variables: Room number only accessor Phone number both mutator and accessor Capacity both mutator and accessor Grade both mutator and accessor 2.Write a Java class called Hotel that represents a hotel.

Write a class RangeInput that allows users to enter a value within a range of values that is provided in the constructor. An example would be a temperature control switch in a car that allows inputs between 60 and 80 degrees Fahrenheit. The input control has “up” and “down” buttons. Provide up and down methods to change the current value. The initial value is the midpoint between the limits. As with the preceding exercises, use Math.min and Math.max to limit the value. Write a sample program that simulates clicks on controls for the passenger and driver seats. PLEASE USE THE TEMPLATES PROVIDED AND ENSURE THAT IT WORKS WITH THE TEST CLASS

For the 'The Chicken class' on the app intelliJ in java. The Chicken class must:• Define three fields called exactly name, pricePerKilo and inStock. The name field must be of type String, the pricePerKilo must be of type int (representing the cost per kilo in pence) and the inStock field must be of type boolean.• Initialise the three fields via a constructor that takes exactly two parameters. The first parameter must be of type String and the second parameter must be of type int. The first parameter must initialise the name field and the second must initialise the pricePerKilo field. The constructor must set the inStock field to true for all Chicken objects. There must be no parameter to the constructor for the inStock field.• Define getters for all three fields using the standard getter naming convention. In particular, note that the getter for the inStock field must be called getInStock rather than isInStock.• Define setters for the pricePerKilo and inStock fields using the standard…
in java, Write a class that represents a student. Every student has a name, an id number, a number of credits, and a number of grade points. Also, include in your class a default constructor, a second constructor with all parameters, an accessor method (getter) for the student name, and a method called gpa that will calculate and return the student’s grade point average. (Hint: gpa = points/credits) Using the class that you just wrote, answer the following questions. Write code that will declare and initialize an object using the default constructor. Write code that will declare and initialize an object using the overloaded constructor. Write code that will retrieve and print the student’s gpa from #2.
