An Invoice should include four pieces of information as instance variables a part number (type String), a part description (type String),a quantity of the item being purchased (type int) and a price per item (double). Your class should have a constructor that initializes the four instance variables. Provide a set and a get method for each instance variable. In addition, provide a method named getInvoice Amount that calculates the invoice amount (i.e., multiplies the quantity by the price per item), then returns the amount as a double value. If the quantity is not positive, it should be set to 0. If the price per item is not positive, it should be set to 0.0.

- A constant object must be__________ ; it cannot be modified after it’s created.arrow_forward01____Write a program that calculates the average of courses, overall grade, and letter grade. Suppose that your students take four courses - English, Mathematics, Science, and History. You should design a class that accepts all four course's numeric scores, calculates average and overall grade, and decides letter grade based on the overall grade. Your class should have a constructor, get and set methods of each course, a method that calculates the average of four courses, a method that calculates overall grade, and a method that decides letter grade. The overall grades are calculated as the following rate: Average of All four courses: 50% Quiz: 40% Attendance: 10% The letter grade is based on the following: 90.0 to 100.0 - A 80.0 to 89.9 - B 70.0 to 79.9 - C 65.0 to 69.9 - D less than 65 - F Your program demonstrates the class by asking the user to input four-course numeric scores, creating an object, and then reporting each course's score, average, overall grade, and letter…arrow_forward__________ is the default behavior when an object is assigned the value of another object of the same class.arrow_forward
- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.arrow_forwardAt most, a class can contain ____________ method(S). 0 1 2 any number ofarrow_forward7) In Java, call-by-value is only used with: objects primitive types this all of the above Answer: 8) The parameter this refers to instance variables local variables global variables the calling object Answer: Pls answer these mcq's 9) When the parameters in a method have the same as instance variables you can differentiate them by using the _____ parameter.
