I am obtaining a StringIndexOutOfBoundsError when running my main method.

Here is the output of my program in the command line.

"Please enter the shift, 1 for day, 2 for night"

 1

"you entered a number for the shift"

"Please enter the hourly pay Rate"

 2

"you entered a number for the pay Rate"

"Please enter the employees name"

Ignore the cat parts in the code, i was using a println statement to test the code. Ignore the value of array output as well, as i wanted to use an array in the program later on.

Here is my main method.
