Complete the Stadium class so that it has an inner class singleton Comparator (sorting strategy) called ByKidZoneCityName that sorts using the following rules: The primary sort field should be if the stadium has a "kid zone" playground. Stadiums that have a kid zone should be listed before stadiums that do not have a kid zone. If two stadiums have the same value for the kid zone, the city (in ascending alphabetical order) should be used to determine the order. If two stadiums have the same value for the kid zone and the city, the stadium name (in ascending alphabetical order) should be used to determine the order

Complete the Stadium class so that it has an inner class singleton Comparator (sorting strategy) called ByKidZoneCityName that sorts using the following rules:
- The primary sort field should be if the stadium has a "kid zone" playground. Stadiums that have a kid zone should be listed before stadiums that do not have a kid zone.
- If two stadiums have the same value for the kid zone, the city (in ascending alphabetical order) should be used to determine the order.
- If two stadiums have the same value for the kid zone and the city, the stadium name (in ascending alphabetical order) should be used to determine the order.
When you are done, your program should produce the following output:
Coors Field, located in Denver, has a kidzone.
Angels Stadium, located in Los Angeles, has a kidzone.
Dodgers Stadium, located in Los Angeles, has a kidzone.
PNC Park, located in Pittsburgh, has a kidzone.
AT&T Park, located in San Francisco, has a kidzone.
Citi Field, located in New York, does not have a kidzone.
Yankee Stadium, located in New York, does not have a kidzone.
Citizens Bank Park, located in Philadelphia, does not have a kidzone.
