    Default Array Out Of Bounds Exception Question

    I Have a question which I'm hoping someone can help me with as I don't know how to write this exception so here it is

    I want Develop a new Exception Class called “Invalid Index Exception” which will inform the user of an attempt to access an invalid index in an array.

    Then I want to give a Java method only called “get Value” which takes 2 parameters, an integer (I) representing the subscript and an integer Array (A), and returns the element at position “I” in the Array “A”. This method should throw an Invalid Index Exception if “I” is not a valid index in the Array “A”.

    You can reinvent the wheel if you want to, but you do not have to.
    But if you want to you can extend Exception or a subclass, like the link above and provide your own functionality

    Thread moved from "Whats wrong with my code?"

    Olliedee,
    You will need to write one user-defined exception class that can extend ArrayIndexOutOfBoundsException.
    Still, you will need to catch ArrayIndexOutOfBoundsException in your source code.
    Then in the catch block you can re-throw your user-defined exception.
    But then how to extract information about array name and index. That I don't know as of now. And I don't know if that is possible also.
    But you can get the cause. I don't know how far "cause" fulfills your requirement.
    Let me know once your dream gets fulfilled. I may be learning new thing.
