Why the compiler can not find the symbol?

I am tryuibg to compile the following using Netbeans.

Code :

---

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. :confused:

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:

Code :

---

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