Здравейте, имам проблем с тази задача, не ми приема решението, бих искал да знам къде греша.
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String digit = scanner.nextLine();
switch (digit){
case "0" :
System.out.println("null");
case "1":
System.out.println("one");
break;
case "2":
System.out.println("two");
break;
case "3":
System.out.println("three");
break;
case "4":
System.out.println("four");
break;
case "5":
System.out.println("five");
break;
case "6":
System.out.println("six");
break;
case "7":
System.out.println("seven");
break;
case "8":
System.out.println("eight");
break;
case "9":
System.out.println("nine");
break;
default:
System.out.println("not a digit");
}
}
}
