Hi,
I am writing an application class for a Lunar Calendar I created in a service class and I have to make sure it is able to detect that the year entered is not in the range of values(I have done this in the service class using a switch statement) and be able to detect if the year is a valid integer. I need a little help with the last one.
Here is what I have so far:
package classes;
import java.util.InputMismatchException;
import java.util.Scanner;
public class LunarCalendarApp {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
final int SENTINEL = -1;
boolean validInput = false;
System.out.println("Enter a year:");
int someYear = in.nextInt();
while(someYear != SENTINEL){
LunarCalendar calen = new LunarCalendar (someYear);
calen.Calendar();
do {
try {
System.out.println("Enter a year:");
validInput = in.hasNext();
someYear = in.nextInt();
}
catch (InputMismatchException e)
{ System.out.println("This is not an integer!");
in.next();
}
}while(!validInput);
}
}
}
