I am attempting to create a java program that reads employee data froma text file and produce a report. I get the following error when running this code:

Java EmployeeSalary Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 4 at EmployeeSalary.main(EmployeeSalary.java:94)

The text file is:

2014 Employee Smith,John 2000 2014 Employee Carrol,Paul 1500 2015 Employee Gorley,Erica 3200 2014 Salesman Greeley,Susan 4500 40000 2015 Salesman Jones,Bill 3000 70000 2014 Executive Bush,George 5000 55 2014 Executive Smith,Frederick 7500 55

The code is below:
