Write a java program for Tlhogi’s Car Care Shop that shows a user a list of available services: oil change, tire rotation, battery check, or brake inspection. Allow the user to enter a string that corresponds to one of the options, and display the option and its price as R25, R22, R15, or R5, accordingly. Display an error message if the user enters an invalid item. Save the file as CarCareChoice.java.
It might not be reasonable to expect users to type long entries such as “oil change” accurately. Modify the CarCareChoice class so that as long as the user enters the first three characters of a service, the choice is considered valid. Save the file as CarCareChoice2.java.
Finally write a test class to test both classes. Save the file as TestCarCareChoice.java
