a. Plan the logic for an insurance company program to determine policy premiums. The program continuously prompts the user for an insurance policy number. When the user enters an appropriate sentinel value, end the program. Call a method that prompts each user for the type of policy needed—health or auto. While the user’s response does not indicate health or auto, continue to prompt the user. When the value is valid, return it from the method. Pass the user’s response to a new method where the premium is set and returned—$550 for a health policy or $225 for an auto policy. Display the results for each policy. b.Modify Exercise 9a so that the premium-setting method calls one of two additional methods—one that determines the health premium or one that determines the auto premium. The health insurance method asks users whether they smoke; the premium is $550 for smokers and $345 for nonsmokers. The auto insurance method asks users to enter the number of traffic tickets they have received…

Create an object called Circle. Declare the following integer variables for the object Circle, radius, diameter, ind pi is declared as double. Create the following for the Circle object: Implicit constructor (default constructor) Void method Calculate (double pi, int radius) to calculate the area of the Circle object. The method must include a system.out statement that displays the area value. Use the following formula to calculate area of the circle: Area = pi* (r* r) %3D our program includes a main class called Shape with a reference c1 to the Circle object. Pass the following alues to the object Circle: radius = 4 diameter = 8 pi = 3.14 nclude output statements to view the values passed to the object Circle.
