Howdy
    I read the message about the person doing a program for their course.
    Your supposed to use the Double.ValueOf() and DoubleValue() methods of
the
java.lang.integer class.
    I would suggest, you (presumably)rewrite the integer.parseint method to
incorporate the
following coded example

double DecVal (String initString) {
        double DecVal = double.ValueOf(initString).doublevalue();
}

This should, give you the decimal equivalent of your string.
Hope this helps
