working on java program computes salaries collection of employees of different types, imported txt file.
the program builds , runs if comment out:
system.out.println("\naverage salary 2014: " + (totalsalary / indexyear2014)); system.out.println("\naverage salary 2015: " + (totalsalary / indexyear2015)); however, not seem data imported/used @ all.
here full code:

the reason works when comment out 2 lines cause divide 0 error. both indexyear2014 , indexyear2015 0.
the reason way you're comparing strings:
year == "2015" should year.equals("2015")
