    Default Constructor parameter

    I want to set a rule...
    If int length is <0 it should be impossible to create a new object of that class.
    Int length is a parameter in the class parameter..
    Any suggestions?

    Here is a link to the tutorial about how to throw an exception: https://docs.oracle.com/javase/tutor.../throwing.html

    When int length is <0 then throw an exception.

    Pass this to google:
    throw exception java
