Answer 1

public class PersonRunner

{

public static void main(String[] args) {

//create a Person object

Person person = new Person("Thomas Edison", "February 11, 1847");

//create a Student object

Student student = new Student("Albert Einstein", "March 14, 1879", 12, 5.0);

//print out the details of the Person object

System.out.println("===========For Person==============");

System.out.println("Name : " + person.getName());

System.out.println("Birthday: " + person.getBirthday());

System.out.println();

//print out the details of the Student object

System.out.println("===========For Student==============");

System.out.println("Name : " + student.getName());

System.out.println("Birthday: " + student.getBirthday());

System.out.println("Grade: " + student.getGrade());

System.out.println("GPA: " + student.getGpa());

}

}

public class Person {

private String name;

private String birthday;

public Person (String name, String birthday) {

this.name = name;

this.birthday = birthday;

}

public String getBirthday(){

return birthday;

}

public String getName(){

return name;

}

}

public class Student extends Person {

private int grade;

private double gpa;

public Student(String name, String birthday, int grade, double gpa){

super(name, birthday);

this.grade = grade;

this.gpa = gpa;

}

public int getGrade(){

return grade;

}

public double getGpa(){

return gpa;

}

}
