    Question How to sum up elements in an array?

    hello java programmers out there im new here and also new to java. I just started java programming lately and I find it really tough yet challenging. And I'm trying really hard to get the hang of java, so I hope you pros out there could help me improve.

    ok here's my question.

    Im trying to sum up all elements in an array so i can find its average.


    For example this code:

    int[] testResults = {80, 82, 62, 49, 16, 18};

    How do I sum up all the elements in that array? And how do I find its average?

    Can anyone give me an example of the code and some explanation. Thanks

    Try a for loop.

    If you get stuck, post code! And the (inevitable) cryptic compiler messages, and describe any crazy runtime behaviour - exceptions or just plain wrong answers.

    For whatever little it's worth my reply was considered and well intentioned. Ignore it. Move upstream and cast a lure in some other bend in the stream. But that's behaviour that will be noticed.
