a. 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 expl ai nRati o () 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 Checkup.java.

b. Create a class named TestCheckup whose main 0 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 mai n D's Checkup objects. Then, in main (), pass each Checkup object in turn to a showVal ues () method that displays the data. Blood pressure values are usually displayed with a slash between the systolic and diastolic numbers. (Typical blood pressure values are 110/78 or 130/90.) With the cholesterol figures, display the explanation of the cholesterol ratio calculation. (Typical cholesterol values are 100 and 40 or 180 and 70.) Save the application as TestCheckup.java.
