The current NDC class doesn't really use the stack in the traditional sense since every 'push' simply concatenates the new string to the end of the existing string.
Couldn't the same thing be accomplished by foregoing the stack altogether and just concatenating the new string to the existing string?
A 'pop' would remove the last string from the concatenated list. It might be necessary to use a second string that contained a concatenated list of the length of the strings.
Thus the actual string might be 'first string second string third string' and the second string would be '12 13 12'. The lengths would be used to determine where the substring is that is being removed (since strings can have embedded spaces). The second string could also be given as '12 25 37' to make it easier to remove the last element.

Mathias,
This is a classical backward compatibility technique. If you can't ensure backward compatibility, then leave the old class alone and create a new one. Those who want NDC can still use it in JDK 1.1. Those who decide to use MDC need JDK 1.2+. Does that make sense? Ceki
