Java Code: "Iterations & I/O" Pulling a file into Eclipse and using it -

with project learning how pull , outside file , use in our eclipse program. in outside file (wordpad) there needs 50 numbers (1-50, new number each line:1 return, 2 return, 3 return, etc.). these numbers have ask user pull in file (with input.txt input, output.txt output). ask user 5 names , average numbers each student. example user enters joe, jack, jill, james, , jake should output:

joe: 5.5 (average of 1-10) jack: 15.5 (average of 11-20) jill: 25.5 (average of 21-30) james: 35.5 (average of 31-40) jake: 45.5 (average of 41-50) 

what guys think? advise or help?

can show me how average numbers successfully. can finish there. thank you.
