I NEED THID FAST PLEASE I NEED IT IN JAVA COMPLETE THE CODE FOLLOW EACH COMMENT

This UJ program will ask the user for three students names, their major and their GPA. The program will then check the validity of the entered GPA. An exception will be thrown if an invalid GPA is entered using IllegalArgumentException class. After reading the required information, the student should create an object from the Student class and store it in the file as object type. The student needs to handle all the expected exceptions that might occur during the writhing or reading process from the file.

Note: there are specific Files associated with this lab exam.
