    Default Java equivalent of Python :-1

    Hi,

    I have some python code which I am trying to convert into a java equivalent for a project at work and am a little stumped over one bit of code.
    I think its a case of I've been looking at this too long that now I've confused myself entirely and my mind has gone blank. Any assistance would be greatly appreciated.

    Sorry but I don't know how to add tags for python code so I hope this works

    validateID is some function
    empID is a unique ID represented as a string of chars in python
    checkDigit is an arbitrary integer.

    My main issue is the :-1.

    if (validateID(empID[:-1]) != checkDigit):
        .....
        .....

    I basically need to know how to convert that line to a java equivalent.

    Thanks in advance.

    My main issue is the :-1.
    Is there a python forum that can describe what that means?

    Does this help: https://stackoverflow.com/questions/...n-do-in-python
    If you don't understand my answer, don't ignore it, ask a question.

    It is list indexing, it returns all elements [:] except the last one -1.

    For now Im using a loop excluding the last element. Seems to work I guess. Thanks.
