import java.util.Scanner;

/*
 *  Scanner class with delimiter(-). 
 */
public class ScannerDemo
{

    public static void main(String[] args)
    {
        Scanner scanner = null;
        try
        {
            String inputValue = "10-20-30-40";
            scanner = new Scanner(inputValue);
            scanner.useDelimiter("-");

            int sum = 0;
            /*
             * Returns: true if and only if this scanner's
             * next token is a valid int value
             */
            while (scanner.hasNextInt())
            {
                /*
                 * Returns: the int scanned from the input
                 */
                int intValue = scanner.nextInt();
                System.out.println(intValue);
                sum = sum + intValue;
            }
            System.out.println("sum = " + sum);
        }
        finally
        {
            if (scanner != null)
            {
                scanner.close();
            }
        }
    }
}
Output
10
