Create a class named BloodData that includes fields that hold a blood type (the four blood types are O, A, B, and AB) and an Rh factor (the factors are + and -). Create a default constructor that sets the fields to "O" and "+", and an overloaded constructor that requires values for both fields. Include get and set methods for each field. Save this file as BloodData.java. Create an application named TestBlood Data that demonstrates each method works correctly. Save the application as TestBloodData.java.

a - Create a FitnessTracker class that includes data fields for a fitness activity, the number of minutes spent participating, and the date. The class includes methods to get each field. In addition, create a default constructor that automatically sets the activity to running, the minutes to 0, and the date to January 1 of the current year. Save the file as FitnessTracker.java. Create an application that demonstrates each method works correctly, and save it as TestFitnessTracker.java.
b - Create an additional overloaded constructor for the FitnessTracker class you created in Exercise 3a. This constructor receives parameters for each of the data fields and assigns them appropriately. Add any needed statements to the TestFitnessTracker application to ensure that the overloaded constructor works correctly, save it, and then test it.
c - Modify the FitnessTracker class so that the default constructor calls the three-parameter constructor. Save the class as FitnessTracker2.java. Create an…

Write a FractionDemo program that instantiates several Fraction objects and demonstrates that their methods work correctly. Create a Fraction class with fields that hold a whole number, a numerator, and a denominator. In addition: Create properties for each field. The set access or for the denominator should not allow a 0 value; the value defaults to 1. Add three constructors. One takes three parameters for a whole number, numerator, and denominator. Another accepts two parameters for the numerator and denominator; when this constructor is used, the whole number value is 0. The last constructor is parameterless; it sets the whole number and numerator to 0 and the denominator to 1. (After construction, Fractions do not have to be reduced to proper form. For example, even though 3/9 could be reduced to 1/3, your constructors do not have to perform this task.) Add a Reduce() method that reduces a Fraction if it is in improper form. For example, 2/4 should be reduced to 1/2. Add an operator+() method that adds two Fractions. To add two fractions, first eliminate any whole number part of the value. For example, 2 1/4 becomes 9/4 and 1 3/5 becomes 8/5. Find a common denominator and convert the fractions to it. For example, when adding 9/4 and 8/5, you can convert them to 45/20 and 32/20. Then you can add the numerators, giving 77/20. Finally, call the Reduce() method to reduce the result, restoring any whole number value so the fractional part of the number is less than 1. For example, 77/20 becomes 3 17/20. Include a function that returns a string that contains a Fraction in the usual display format—the whole number, a space, the numerator, a slash (D, and a denominator. When the whole number is 0, just the Fraction part of the value should be displayed (for example, 1/2 instead of 0 1/2). If the numerator is 0, just the whole number should be displayed (for example, 2 instead of 2 0/3). b. Add an operator*() method to the Fraction class created in Exercise 11a so that it correctly multiplies two Fractions. The result should be in proper, reduced format. Demonstrate that the method works correctly in a program named FractionDemo2. c. Write a program named FractionDem03 that includes an array of four Fractions. Prompt the user for values for each. Display every possible combination of addition results and every possible combination of multiplication results for each Fraction pair (that is, each type will have 16 results).arrow_forwardWhich 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.

- Open the Palace Solution.sln file contained in the VB2017\Chap10\Palace Solution folder. Use Windows to copy the Rectangle.vb file from the VB2017\Chap10 folder to the Palace Project folder. Then, use the Add Existing Item option on the Project menu to add the file to the project. Modify the Rectangle class to use Double variables rather than Integer variables. Change the name of the GetArea method to GetAreaSqFt. Add another method to the class. Use Get AreaSqYds as the method’s name. The method should calculate and return the area of a rectangle in square yards. The application’s Calculate button should calculate and display the number of square yards of carpeting needed to carpet a rectangular floor. Code the btnCalc_Click procedure. Display the number of yards with one decimal place. Save the solution and then start and test the application.arrow_forwardEverything is in the attached picture! Thank you so much!arrow_forwardDirections This exercise will provide you with the opportunity to utilize NetBeans to create an application that calculates interest. End Result: Console Create the Scanner object. Get the loan information from the end user by using the System class. Calculate the interest amount by using the BigDecimal class to make sure that all calculations are accurate. Format the interest rate, interest amount and loan amount and interest by using the NumberFormat abstract base class. It should round the interest that’s calculated to two decimal places, rounding up if the third decimal place is five or greater. The value for the formatted interest rate should allow for up to 3 decimal places. Display the results by using the System class. Assume that the user will enter valid double values for the loan amount and interest rate. The application should continue only if the user enters “y” or “Y” to continue.arrow_forward
