    This program will not give me the average high temperature for the week and I cannot figure out why! Every time it only spits out "0" whereas the average low temperature works great... Please help!

    Default Re: Will not average for high temp

    Is the code using integer math? 4/6 = 0
    or floating point? 4/6.0 = 0.6666
    If you don't understand my answer, don't ignore it, ask a question.

    it only spits out "0"
    Can you copy the output and post it here that shows what the code outputs?

    Try debugging the code by adding some println statements to the code where the value is computed. Print out the values of all of the inputs and the values of all the intermediate results so you can see what the code is doing and where it is going wrong.

    I use the println method to print values on the console:
     System.out.println("aH1="+aveHigh1); // show variable's value
    Add the above after the line that computes the value.
    Do the same for all the other variables that are used.
    If you don't understand my answer, don't ignore it, ask a question.
