By default in java, any number with a decimal in it is considered/read/treated as a double data type. To get this into a long data type you would have to cast it to a long. But then you won't get it to print out as a double, ie, with two decimal places.

Code:

public class Test {
    public static void main(String[] args) {
        String stotal = "99998900001.00";
        // NumberFormatException
//        long error = Long.parseLong(stotal);
        double okay = Double.parseDouble(stotal);
        System.out.printf("okay = %.2f%n", okay);
        long toLong = (long)okay;
        long again = Double.valueOf(stotal).longValue();
        System.out.printf("toLong = %d  again = %d%n",
                           toLong, again);
    }
}
