Question

 // Instances of this class represent a person.   // // Complete the methods of this class so that it passes the tests.    public class Person  {   final String name;   final int age;    public Person (String name, int age) {     this.name = name;     this.age = age;   }    public String toString () {     return "Person("" + name + "", " + age + ")";   }    // EXERCISE 1: Provide an implementation of the "hashCode" method  //following the criteria laid out in the textbook and slides.   // In "hashCode" and "equals" below, you should assume that people are equal if and only if //they have the same name and age,  //i.e., there cannot be more than one person with name "alice" and age 50.   public int hashCode () {     // TODO: Complete this method.     return 17;   }    // EXERCISE 2: Provide an implementation of the "equals" method following the criteria laid //out in the textbook and slides.   public boolean equals (Object o) {     // TODO: Complete this method.     return false;   } } 

Explanation / Answer

implementation

This will be the below function implementation.

public boolean equals(Object o) {
        if (o instanceof Person) {
            return ((Person)o.age.equals(this.age);
        }
    }

    @Override
    public int hashCode() {
        return this.age.hashCode();
    }
