Write a java program that can be used by a policeman to determine if a vehicle has exceeded the speed limit and to levy a fine. The policeman should enter the vehicles speed and the speed limit. If the speed limit is exceeded by less than 30kph a fine of Kshs. 2500 should be charged. Otherwise a fine of Kshs 4000 is charged. Your program should then output (in a suitable format) the vehicle speed, the speed limit, the excess speed and the fine levied.
