Description

1         The classes:

.a         People class – 3 data members (id, name, gender) & rfunctions.

.b         Faculty class – a subclass of People, with new data members (department, years of service) & new functions (as needed).

People class

Faculty class

public class People {protected int id;protected String name;protected char gender;public People( ) {  }public People(int i, String n, char g) {

id=i; name=n; gender=g;

}

public void getData( ) {

System.out.print(“id=”+id+”, name= ” +name+”, gender=”+gender+”, “);

}

}

public class Faculty extends People {protected String dept;protected int yos;public Faculty( ) {   }public Faculty(int i, String n, char g, String d, int y) {  super(i, n, g); dept=d; yos=y;  }public void getData( ) {

    super.getData( );

System.out.print(“dept=”+dept+ “, years of service=”+yos);

}

}

Note: (#1) The getData function of the Faculty class overrides the getData function of its superclass.  This is called function overriding (not function overloading).  (#2) The getData of Faculty is calling the getData of People by using super.getData( ).  This expression consists of the keyword super which identifies its superclass, & the function in the superclass to be called into action.

.c         Student class – a subclass of People, with new data member GPA & new functions.

.d        GStudent (GraduateStudent) class – a subclass of Student, with new data members (major, earned credits) & new functions.

Student class

GStudent class

public class Student extends People {protected double gpa;public Student( ) {   }public Student(int i, String n, char g, double a){     super(i, n, g); gpa=a;   }

public void getData( ) {

super.getData( );

System.out.print(“GPA=”+gpa+”, “);

}

};

public class GStudent extends Student {protected String major;protected int credits;public GStudent( ) {   }public GStudent(int i, String n, char g, double a, String m, int c){  super(i, n, g, a); major=m; credits=c;  }

public void getData( ) {

super.getData( );

System.out.print(“Major=”+major+”, credits”+credits);

}

};

.e         E32 program class – to instantiate objects of the 4 data types.

Program class “E32”

public class E32{public static void main(String [ ] args){Faculty f1 = new Faculty(111, “John Smith”, ‘M’, “CIS”, 12);Student s1 = new Student(999, “Susan Johnson”, ‘F’, 3.25);

GStudent g1 = new GStudent(555, “Jennifer Lopez”, ‘F’, 3.66, “CIS”, 22);

f1.getData( ); System.out.println( );

s1.getData( ); System.out.println( );

g1.getData( ); System.out.println( );

}

}

 

Output:

 

Modify E32 program based on the following information:

 

1      Add a new data member DOB (or, date of birth) to the People class.

2      Modify the class function(s) to reflect the impact of adding a new data member.

3      Modify the sub-classes to reflect the changes occurred in the super class.

4      Add DOB data (of your choice) to all objects.

5      Display all objects.
