COMPLETE THE CODE

Task #2 Import the required packages

In order to read and write object into a file, you need to import the required classes that help to perform the required tasks.

Task #3 writing objects to a file

You need to create objects from the FileOutputStream, and ObjectOutputStream in order to be able to write objects to a file.

Note: please name the file (UJStudents.dat)

Task #4 try-catch statement

The main method contains a loop that will read a student name, his major and his GPA from the user. The main method should contain a try-catch statement. This statement tries to check if the GPA is valid by using IF statement. If the GPA is valid, it creates the Student Object. Otherwise, an IllegalArgumentException is thrown, the main should catch it and print out the name and an associated error message indicating why the GPA is invalid and ask the user to re-enter the valid GPA (it should be in a loop)

Note: the entered GPA should be between 0 to 5

Task #5 Object file (Writing)

Task 5.1: Once you create the Student object successfully, and to serialize this object and write it to the file, the ObjectOutputStream classs writeObject method is used.

Note: during the writing process, The writeObject method might throw an IOException if an error occurs, so make sure to handle this kind of exception.

Task 5.2: please close the file

Task #6 Object file (reading)

Task 6.1: To deserialize an object an ObjectInputStream object is used in conjunction with a FileInputStream object.

Note: please open the file (UJStudents.dat)

Task 6.2: to read a serialized object from the file, the ObjectInputStream classs readObject method is used. The readObject method returns the deserialized object.

Notice that you must cast the return value to the desired class type.

Note: The readObject method throws a number of different exceptions such as ClassNotFoundException, and IOException if an error occurs, so make sure to handle this kind of exception.

Task 6.3: please close the file
