IN JAVA
Create the following classes:
The Transcript class is designed to hold information on all the courses a student has taken. As such you
will need to find a way to an unknown number of CourseRecord objects within each Transcript object.
The Transcript object is also responsible for calculating the student’s GPA. GPA is calculated as the sum
of the grade points for each course, divided by the total number of credits.
Transcript Class API Method Header Notes
public Transcript( String name ) Constructor takes arguments specifying a student’s name.
public String getName() Returns the student’s name.
public void addCourse(String
number, String name, int credits,
char grade) Creates and stores a CourseRecord object in this Transcript.
public double getGPA() Returns the student’s GPA.
public String toString() Returns a String containing the student\'s name on one line, the
student’s GPA on the next line and each CourseRecord object
stored in this Transcript object on its own line after that
The RecordSystem class is designed to hold the Transcripts for all students at an institution. As such you
will need to find a way to an unknown number of Transcript objects within each RecordSystem object.
As implemented here, the RecordSystem object has minimal functionality (feel free to add more, as long
as you do not break the core requirements. Note that the individual Transcript objects stored in the
RecordSystem object will be accessed using the getStudent( int index ) method.
RecordSystem Class API Method Header Notes
public RecordSystem() Default constructor.
public int addStudent( String name ) Creates and stores a Transcript object in this RecordSystem.
Returns an int corresponding to the index where the Transcript
was stored.
public Transcript getStudent( int index ) Returns a reference to the Transcript object stored at location
“index”
public int maxGPAindex() Returns the index of the Transcript object that has the highest
GPA.
public int maxGPA() Returns the GPA of the Transcript object that has the highest
GPA.
public int maxGPAname() Returns the student name of the Transcript object that has the
highest GPA.
public String toString() Returns a String containing all Transcript objects stored, each
separated by a divider of ‘*’s.
