I'm doing this assignment in Java, and its really confusing me. Just wondering if anyone is willing to help. Having said that, I do not want this done FOR me, but help will be nice ^^
What we have to do it program a reverse swedish notation calculator. We have been given a class called DoubleStack.java to complete. Included was a testapplication written by the lecturer that we could run, to see if the individual methods in the class work. However for one particular method, I get a NoSuchMethodError.
Heres a screenshot:
Any ideas? =(
