    Unhappy Matrix Message

    When I tried to input some double to matrix, I got this message :

    Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 2
    at sistemspl.Matrix.main(Matrix.java:37)
    Java Result: 1


    I don't understand it. What should I do?

    Your code appears to have an array, and on line 37 of the Matrix class code, you appear to be accessing the 2nd item in an array that holds less than 2 items.

    If you want more help, you'll need to provide more detail here, much more detail including code. A great resource that has helped me and will probably help you is an article entitled How To Ask Questions The Smart Way. It will tell you how to formulate your questions so that the folks here will be better able to answer them. Good luck.

    At least, did you read more about the exceptions you get on the web Or Java doc?

    ArrayIndexOutOfBoundsException (Java 2 Platform SE v1.4.2)

    It's more clearly explain what's wrong with your code? As Fubarable says, if you can provide more details we can help you.
