    }

this is my program to implement tourism program User Requirements - A city has many attractions and the attractions can be classified into various types. To view the detailed information of an attraction, a tourist will first choose a city from a list of cities displayed in alphabetical order, the type of attraction from a list of attraction types and then the attraction itself. He can also choose a city and then choose from a list of all attractions in the city without choosing a type of attraction. The maximum number of attractions per city must not be fixed in the system. - The user interface has to be user-friendly so that users can navigate with ease. Design a console-based user interface for the system. can i know how to implement in the next step,anyone can give me suggestion?
