This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
I am getting an "java.lang.ArrayIndexOutOfBoundsException" error in the code below I think it might be at sum = average[i]; but I do not see why I am throwing that error ? The array element has an index of 16 , reading off a .txt file . Ok, please let me know if you can see what I am doing incorrectly ? Thank you.
You need to check the format of a for loop when iterating an array. Unfortunately there isn't a good example in the Java Tutorials; you should find something in your textbook. Look at the binary operators very carefully.
assuming that you have 16 elements for input here is what you did wrong
consider this line
you declare a string array with 16 elements , the index being 0 to 15( 15(1st to 15th index ) + 1(0th index ) )
it takes elements from intFile(1st element at 0th index ... 4th element at 3rd index and 16th element at 15th index)
so avarage infact represents your 16th element(15 is the index here)
in the following array iteration for loop at this line
the <= makes it iterate from 'zero' to 16 th (i.e., your array should have 17 elements)
so just remove '=' sign and change line to
Note: maxList.size() return 16 because you array has 16 elements indexed from 'zero' to 15
