I am a complete beginner in JAVA and now have to do this for a class.
Task is to read a text file and store the values in appropriate places. Its hard to describe the assignment, so all i want to know as a starting step is once you have read a file, how do you do basic things like using the text file to calculate averages.
For example if a line from the text file is

How do i break these apart and calculate the average of these three numbers and set the average to that particular date. So when a user selects that date from a dropdown box the average should be displayed.
I am just soo Lost and I just want someone to explain to me the code and just a starting tip.
