Question

Java Programming. Please make sure program compiles, the code is copyable, and screenshots of the output are provided for 5 stars :-) Calculation for speed is just supposed to be google searched

1) 18 points] You've been hired by Pedal Punchers to write a Java console application that estimates bicycle speed in miles per hour. Use a validation loop to prompt for and get from the user the wheel diameter of a bicycle in inches in the range 10-50. Then use a validation loop to prompt for and get from the user the number of rotations the bike wheel makes per pedal rotation in the range 0.1-10. Then use a validation loop to prompt for and get from the user the number of pedal rotations per minute in the range 1-120. Format the following output in two columns with the first column containing a label and the second column containing the result. Format any real numbers to three decimal places The three inputs. o o The estimated speed based on the three inputs Use Math PI in your calculation. Continue to prompt the user for estimates until they enter "n". Use this data for the last three inputs Wheel diameter Wheel-to-pedal ratio Pedal rotations per minute 24 34 27 2.5 40 30 10 17
