Question 1, 2 & 3 deal with the given code below:

public class Human {

private int age;

private String name;

public Human(int age, String name) {

this.age = age;

this.name = name;

}

public String toString() { return " Age: "+ age +" Name: "+name ; }

public int getAge() { return age; }

public String getName() { return name; }

public String talkToMe() { return " Human "; }

}

public class Professor extends Human {

private double salary;

public Professor(double salary, String name) {

super(45, name);

this.salary = salary;

}

public String toString() { return super.toString() + " Salary: "+ salary; }

public double getSalary() { return salary; }

public String talkToMe() { return " Professor "; }

}

1. What is the output,

public class Q1 {

public static void main(String[] args) {

Human h = new Human(72 , "Mac");

Professor p = new Professor(25.7, "Poof");

check(h);

check(p);

}

public static void check(Human h2) {

System.out.println( h2.toString() + " , " + h2.talkToMe());

}

}

Answer:

2. what is the output

public class Q2 {

public static void main(String[] args) {

Professor p = new Professor(7600,"prof");

System.out.println(p.getName()+ " , "+p.getAge()+ " , "+p.getSalary());

}

}

Answer:

3. For class Professor, fill in the body of method equals below. A given Professor object is equal to another Professor object if their salary, name and age are all the same. [1,1,,=6]

public boolean equals(Professor f) {

return (getName().equals(f.getName() ) &&

getAge() == f.getAge() &&

salary == f.salary();

}
