System.out.print("Enter an integer: ");
//use a try-catch block to detect any exceptions
try
{
int number = input.nextInt();
//display the number entered by the user
System.out.println("You entered " + number);
//set continueInput to false to exit the while loop
continueInput = false;
}
//catch any exceptions and display appropriate message
catch (java.util.InputMismatchException ex)
{
System.out.println("You must enter an integer. Please try again.");
