I am having trouble reading the entire file and placing it into the array. It keeps leaving out the last 2 numbers in my txt file. What am I doing wrong in my createArr() method that is causing this. Also, my method avgTimeTemp() is not producing any output other than the first line. I included my text file contents below and output.
