Question

I need to see a working example using inheritance and the classes (below)

• The person class has
  • first name
  • last name
  • age
  • hometown
  • a method called getInfo() that returns all attributes from person as a String
• The student class is a person with
  • an id and
  • a major and
  • a GPA
  • student has to call super passing the parameters for the super class constructor
  • a method called getInfo() that returns all attributes from student as a String
    • this methods has to override the method getInfo() in person
• The student-athlete class is a student with
  • a sports (football, or track, or soccer, volleyball, etc.)and
  • a ranking (a random number between 0 and 100)
  • student-athlete has to call super passing the parameters for the super class constructor
  • a method called getInfo() that returns all attributes from student-athlete as a String
  • this methods has to override the method getInfo() in student

Create an application (app) that:

• Creates one student-athlete object.
• Displays all information about the student-athlete object
• Does it in the most efficient way possible (avoids unnecessary duplication of attributes and methods)
• Uses the classes
  • app
  • person
  • student inheriting from person
  • student-athlete inheriting from student

This code is written in java language.

Please find it.

class Person

{

String firstname;

String lastname;

byte age;

String hometown;

Person(firstname,lastname,age,hometown)

{

this.firstname=firstname;

this.lastname=lastname;

this.age=age;

this.hometown=hometown;

}

String getInfo()

{

return this.firstname+this.lastname+this.age+this.hometown;

}

}

class Student extends Person

{

byte id;

String major;

float GPA;

Student(firstname,lastname,age,hometown,id,major,GPA)

{

super(firstname,lastname,age,hometown);

this.id=id;

this.major=major;

this.GPA=GPA;

}

String getInfo()

{

return super.getInfo()+this.id+this.major+this.GPA;

}

}

class Student_athlete extends Student

{

String sport;

byte rank;

Student_athlete(firstname,lastname,age,hometown,id,major,GPA,sport,rank)

{

super(firstname,lastname,age,hometown,id,major,GPA);

this.sport=sport;

this.rank=rank;

}

String getInfo()

{

return super.getInfo()+ this.sport+this.rank;

}

}

class App

{

public static void main(String [] args)

{

Student_athlete student_athlete = new Student_athlete("robin","marshal",25,"Maryland",23,"CS",9.0,"football",23);

System.out.println(student_athlete.getInfo());

}

}
