4. Student.java and DemoStudent.java updates (suggest copying these from Project 1 work into a new folder) a. Add a method to Student.java called getLevel. This method accepts the number of credits a student is taking and returns a String, depending on the number of credits: i. 0-5 credits - returns "Part-Time Student" ii. 6-8 credits - returns "Half-Time Student" iii. 9-11 credits -returns "Three-Quarter Student" iv. 12 or more credits - returns "Full-Time Student" b. Add code to DemoStudent.java: i. In the keyboard input section, do not let the user enter less than 0 or more than 20 for the number of credits. ii. Display the student's level for firstStudent, secondStudent, and third Student by calling the getLevel method. 5. WriteMyFile.java and ReadMyFile.java - Write an application that creates a text file that consists of an inventory of items you would want with you if you were ever stranded on a desert island. Then write the application that reads and displays that data
