the population, and two City objects that hold data about the capital city and the most populous city. The
State constructor requires six parameters that represent the names and populations of the state, its capital,
and its most populous city. Provide get methods for each field. Create the City class to be a nonstatic, private
inner class within the State class; the City class contains a city’s name and population. Create a class to assign values to and display values from two State objects. Save the files as State.java and TestState.java.
