Given a main program that searches for the ID or the name of a student from a text file, complete the findlID) and the findName) methods that return the corresponding information of a student. Then, insert a try/catch statement in main() to catch any exceptions thrown by findID() or findName(), and output the exception message. Each line in the text file contains the name and the ID of a student, separated by a space. Method findID0 takes two parameters, a student's name and a Scanner object containing the text file's contents. Method findID) returns the ID associated with the student's name if the name is in the file, otherwise the method throws an Exception object with the message 'Student ID not found for studentName", where studentName is the name of the student. Method findName) takes two parameters, a student's ID and a Scanner object containing the text file's contents. Method findName() returns the name associated with the student's ID if the ID is in the file, otherwise the method throws an Exception object with the message 'Student name not found for studentlD", where studentID is the ID of the student. The main program takes three inputs from a user: the name of a text file (String), a user choice of finding the ID or the name of a student (int), and the ID or the name of a student (String). If the user choice is 0, findID0 is invoked with the student's name as one of the arguments. If the user choice is 1, findName() is invoked with the student's ID as one of the arguments. The main program finally outputs the result of the search or a message if an exception is caught.
