Create a class named Book that has 2 private variables, the first variable stores the title and the second variable stores number of pages in a book. And it contains the following methods: setNo() - Used to set the number of pages in the book. getNo() - Used to return the number of pages in the book. setTitle() - Used to set the title of the book getTitle() - Used to return the title of the book

Create a class named Checkup with fields that hold a patient number, two blood pressure figures (systolic and diastolic), and two cholesterol figures (LDL and HDL). Include methods to get and set each of the fields. Include a method named computeRatio() that divides LDL cholesterol by HDL cholesterol and displays the result. Include an additional method named explainRatio() that explains that HDL is known as “good cholesterol” and that a ratio of 3.5 or lower is considered optimum. Save the class as CheckupType.cpp. Create a tester program named TestCheckup whose main() method declares four Checkup objects. Call a getData() method four times. Within the method, prompt a user for values for each field for a Checkup, and return a Checkup object to the main() method where it is assigned to one of main()’s Checkup objects. Then, in main(), pass each Checkup object in turn to a showValues()method that displays the data. Blood pressure values are usually displayed with a slash between the…
Create a class called FinalGrade that is used to represent the points obtained in the letter grade of CSC 110 by different students. The FinalGrade class should include three pieces of information as instance variables—studentName (type String), studentID (type String), and pointsObtained (type int). Your class should have a constructor that initializes the three instance variables. Provide a set and a get method for each and every instance variable. In addition, provide a method named computeLetterGrade that returns the letter grade obtained by the student taking the pointsObtained as an argument. For the grading policy refer to CSC 110 grading scheme specified in syllabus. Write a test application named FinalGradeDriver that creates at least 3 different objects of class FinalGrade and test all the methods of class FinalGrade. Sample Output Student Name : Homer SimpsonStudent ID : S123456Points Obtained : 99Letter Grade : A Student Name : Marge SimpsonStudent ID : S234567Points…
Create a class named Student that has fields for an ID number, numberof credit hours earned, and number of points earned. (For example,many schools compute grade point averages based on a scale of 4, so athree-credit-hour class in which a student earns an A is worth 12 points.)Include methods to assign values to all fields. A Student also has a field forgrade point average. Include a method to compute the grade point averagefield by dividing points by credit hours earned. Write methods to display thevalues in each Student field. Save this class as Student.java.b. Write a class named ShowStudent that instantiates a Student object from theclass you created and assign values to its fields. Compute the Student gradepoint average, and then display all the values associated with the Student.Save the application as ShowStudent.java.c. Create a constructor for the Student class you created. The constructor shouldinitialize each Student’s ID number to 9999, his or her points earned to 12,…
Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the reference of any child class object. That…
(The Rectangle class) Following the example of the Circle class in Section 8.2,design a class named Rectangle to represent a rectangle. The class contains:■ Two double data fields named width and height that specify the width andheight of the rectangle. The default values are 1 for both width and height.■ A no-arg constructor that creates a default rectangle.■ A constructor that creates a rectangle with the specified width and height.■ A method named getArea() that returns the area of this rectangle.■ A method named getPerimeter() that returns the perimeter.Draw the UML diagram for the class and then implement the class. Write a testprogram that creates two Rectangle objects—one with width 4 and height 40and the other with width 3.5 and height 35.9. Display the width, height, area,and perimeter of each rectangle in this order.

create a class named checkup with fields that you read a patient number, blood pressure figures (systolic or diastolic), and two cholesterol figures (ldl and hdl). include a method named computeratio() that divides ldl cholesterol by hdl cholesterol and displays the result. include an additional method named explainratio() that explains that hdl is knowns as “good cholesterol” and that a ratio of 3.5 or lower is considered optimum pseudo code
Create a class IndependenceUSA and write code which asks the user to enter text that contains the American Independence day ( July 4th 1776). Read the date using the method next() 3 times. The user should enter the Independence day in the order month, day, year as shown in the first two runs below( we are not case sensitive) . Use the String method compareToIgnoreCase() to test the validi-ty of the date and print “Hurrah!” if the date entered is correct, or “No, no , no! Incorrect!” if the date incorrect is incorrect, or of the date entered in the wrong order. In other words, you compare your input to “July” , “4”, “1776” , in that order and you don't case for capital or small case letters.
Create a class called Date that includes three instance variables-a month (type int), a day (type int) and a year (type int). Provide a constructor that initializes the three instance variables and assumes that the values provided are correct. Provide a set and a get method for each instance variable. Provide a method displayDate that displays the month, day and year separated by forward slashes (/). Add a main method to the class that demonstrates class Date's capabilities.
Which of the following statements is false? a. A class can contain only one constructor. b. An example of a behavior is the SetTime method in a Time class. c. An object created from a class is referred to as an instance of the class. d. An instance of a class is considered an object.
This is java question: Create a class named Bottle, which contains the following attributes: isFull (boolean), drinkType (ex: water), fillLevel (max: 100). Then, create a method called drink, which takes an argument of how much liquid the user drinks. When the user calls drink, subtract the amount drank from the fillLevel and make sure that isFull is set to false. Lastly, create a constructor that initializes the object as a full bottle containing water.
