Write a program called AveMethod (main method) that contains a method called  threeAve (method name) that computes the average of three numbers.  a) The main method will do the following:  • asks the user for 3 number (double type).  • calls the threeAve method • print the average of the three numbers b) The threeAve method will do the following:  • receives 3 numbers (parameters) • calculate the average of the three numbers • returns the average Sample Run:  Input the first number: 2.5 Input the second number: 3.5 Input the third number: 6.6 The average is 4.2

Write the following two methods: computeDiameter: This method accepts the radius (r) of a circle, and returns its diameter (2*r; radius = 7.5).   Declare all variables used here & initialize radius:     Show method call:            Write method code here:                           displayData: This method accepts two arguments: radius & diameter.  The output should have appropriate messages on the screen.   Show method call:                        Write method code here:

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…
