syntax error

[gaurav_kl]

also plz tell if there is nething wrong in this piece of code-

public static final Integer multiply(Integer x, Integer y) {
return (y == 0) ? 0 : multiply(x, y - 1) + x;
}

I think as the return type is static and final we can't return different value everytime?

that just means that the Integer you are returning cannot be subclassed . Doesn't mean that there is only one answer returned by the method.
