For the FileOperator class, the class skeleton is already provided to you. The only method
you should modify and implement is writeFile. This method takes an array of employees,
and each element can be a Faculty object or a StudentWorker object. Your task is to
identify the type of the object using the instanceof keyword and write a line representing this
object to the file using reference m_file. If the current object is a Faculty, then add a prefix
"F-" to the string returned by getPaycheck and write this line to the file. Otherwise, if the
current object is a StudentWorker, the prefix should be "S-". For example:
S-Optimus Prime-Computer Science-$1200
F-Pooh-Mathematics-$50000
