The only methodyou 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 toidentify the type of the object using the instanceof keyword and write a line representing thisobject 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 thecurrent object is a StudentWorker, the prefix should be "S-". For example:S-Optimus Prime-Computer Science-$1200F-Pooh-Mathematics-$50000
