Population Database Compile and run CreateCityDB.java which will create a Java DB database named CityDB. The CityDB database will have a table named City, with the following columns: CityName & Population. Their Data Types: CHAR(50) Primary Key & DOUBLE. The CityName column stores the name of a city, and the Population column stores the population of that city. After you run the CreateCityDB.java program, the City table will contain 20 rows with various cities and their populations. Next, create an application that connects to the CityDB database and allows the user to select any of the following operations: Sort the list of cities by population, in ascending order. Sort the list of cities by population, in descending order. Sort the list of cities by name. Get the total population of all the cities. Get the average population of all the cities.
