I am having trouble figuring out the "deleteStudent" method, which has confused me about understanding the "deleteStudentByShifting" method, both of which are described in the JavaDoc in theCourse classand I need to output that in the Lab11App. This is my first time extracting data from an input file (text file), and I can't seem to get these parts correct. There are four different classes and a text file. Classes are Course, Lab10App, Lab11App, and Student. The text file is courseData.txt. Thank you
