  student Define a Student class with the following specifications Fields String name //should be last name, first name int studentID double gpa . . int gradeLevel . char gender Methods Constructors o Must have 3 constructor methods, a default, a comprehensive, and another of your own design Setters/getters as appropriate .public void advance //advances the student to the next grade. Decide what to do for a senior public int graduate ) //returns the years left until graduation (seniors have 1 year) student has studied public void study (int hours) //displays a message saying how many hours the Write a test class that fully tests your class Define and test 2 classes, Student and StudentRoster. The classes are described below class Student Class fields name (in the form "lastname, firstname") grade level gpa Stringl schedule (7 classes) student id Methods 3 constructors (default, comprehensive, and 1 more of your choice) setters and getters, as appropriate equals() toString) schedule modifiers add a class to schedule given a String argument for the class boolean method that returns true if class is added and false otherwise. A class can be added if there is room in the array. The class should be added to the first "empty" index. delete a class from the schedule given a String argument for the class boolean method that returns true if class is deleted and false otherwise. If the requested class is not in the schedule, false is returned. If a class is deleted, the period should be reset to nul access a class by period Given an int argument for period, returns the name of the class. If there is no class that period, the word "unscheduled" is returned graduate, advance and study as previously discussed class StudentRoster Class fields Student[ roster int classSize Methods 1 default constructor receives an int argument to set the size of the roster array Accessor methods for class data . getter for classSize o access method for a student given student id. Should return a Student object, or null if student is not found add student adds a student to the classroom roster. Student is added to the end of the students already in the array . If roster is full, student is not added and roster is unchanged boolean method. Returns true if successful, false otherwise delete student . deletes a student from the roster, given an id argument boolean method-return true if deletion successful, false otherwise if the argument is not found in roster, roster is unchanged and false is returned . There shouldn't be gaps in roster after a deletion. Students are deleted in actuality by being written over by elements to the right as they are shifted left. Elements of roster should be shifted left after a deletion from the index of the deleted student and the logical size of the array should be decremented Ex. Assume student 123 is to be deleted from roster before 789, 456, 123, 321, 654, 987 after 789, 456, 321, 654, 987, 987) logical size: 6 logical size: 5 note: Notice that after sliding elements to left to "cover up" student 123, there are now 2 987s listed. That is why we need to keep track of the logical size (actual number of students) of roster. After decrementing the logical size on deletion, the effective size of the array is decreased Display type methods class roster returns a String representation of a list of all the student names in roster by grade level returns a String representation of all the student names in a given grade in list form student schedule returns a String representation of a given student's schedule headed by the name toString() returns a String representation of the full roster You may use the provided shells to help you define the classes. I have provided a small (incomplete) test class for StudentRoster. Note that there is further testing necessary to fully test StudentRoster
