imagine a program that reads the population of a city using the following

statements:

System.out.print("Enter the population of the city: ");

int population = keyboard.nextInt( );

Write a while loop after these statements that ensures that population is

positive.       if the user enters a population that is either negative or zero, ask

the user to enter a nonnegative value.
