Repeat the following until currCity's readNameAndPopulation$()$ method returns false:

Assign currCity with a new City object.

Use currCity's readNameAndPopulation$()$ method to read each pair of inputs, string name and integer population.

If currCity's readNameAndPopulation$()$ method returns true, append currCity to ArrayList cityList.

Ex: If the input is Bow $1400$ Adomstown $4900$ Jackson $1700$ Sundance $2600$ end, then the output is:

City: Bow, Population: $1400$ City: Adomstown, Population: $4900$ City: Jackson, Population: $1700$ City: Sundance, Population: $2600$
