You are not passing any args to this functions it seems. How are you calling this functions — Sam Orozco, Jul 13 '18 at 06:27
Show us how you are running this class. The error indicates that `args[]` is empty. — Tim Biegeleisen, Jul 13 '18 at 06:27

If you're running this on netbeans, you can pass arguments into the main method by right clicking on the project, pick properties (it's at the bottom), click on the run category and then underneath Runtime Platform and Main Class is a text field to enter arguments.

If you're calling it from the command line, e.g. running javac and passing it the main class name, just add two command line arguments after the class name.
