    Unhappy Why the compiler can not find the symbol?

    I am tryuibg to compile the following using Netbeans.
    public class Example1 {
         public int sumOfDigits(int n)
         {
     
              int sum = 0;
              n = Math.abs(n);
              while (n > 0)
              {
                   sum += n % 10;
                   n /= 10;
              }
              return sum;
         }
         public void inputAndProcess(Input in)
         {
              System.out.print("Type an integer: ");
              int n = in.nextInt();
              System.out.print("The sum of the digits of: " + n);
              System.out.println(" is: " + sumOfDigits(n));
         }
     
         // The main method should do no more than create the object
         // and call a method to do the work.
         public static void main(String[] args)
         {
              new Example1().inputAndProcess(new Input());
     
         }
    }
    The compilation gives me 2 errors (actually the same error twice) :
    Can NOT find Symbol class Input location class Example1

    I am using the latest Java JDK. What should I do? Please help.

    Default Re: Why the compiler can not find the symbol?

    Input isn't a default Java API class. You either need to write it yourself or get it from someone. If you want to just get input from the user, try using a Scanner object:

    public void inputAndProcess(Scanner in)
    {
         // your code above is fine
    }
     
    public static void main(String[] args)
    {
         new Example1().inputAndProcess(new Scanner(System.in);
    }
