To write a program that keeps names and email addresses in a dictionary as key-value pairs check the code given below.

<h3>What is key-value pairs?</h3>

In a key-value pair, two related data elements are combined: a value, which is a variable that belongs to the set (for example, male/female, green, 100), and a key, which is a constant that defines the data set (for example, gender, color, price).

A key-value pair could look something like this when fully formed:

gender = male

color = green

price > 100

miskamm [114]

Answer:

Check the explanation

Explanation:

Note : check attached image for output and program and also note that you're to replace "at" with shift 2 as the brainly text editor can't take the symbol

Program : **************Magzine.java**********************

/*

* To change this license header, choose License Headers in Project Properties.

* To change this template file, choose Tools | Templates

* and open the template in the editor.

*/

public class Magzine {

 

//class variable private can not access outside class

private String title;

private String month;

private int year;

 

//parameterized constructor

public Magzine(String title,String month,int year)

{

this.title=title;

this.month=month;

this.year=year;

}

 

//override toString method

"at"Override

public String toString()

{

String detail=title+" "+month+" "+Integer.toString(year);

return detail;//return string of class variable

}

 

//get Magzine objecte

 

public boolean equals(Magzine obj)

{

//commented returm statement compare string by address so you can uncomment if

//we do not use same string object of String class

//return this.month==obj.month && this.title==obj.title && this.year==obj.year;

//compare two object element if matches return true else false

return (this.month.equals(obj.month)) &&(this.title.equals(obj.title)) && this.year==obj.year;

}

   

}

Program : *************************Main.java****************************

/*

* To change this license header, choose License Headers in Project Properties.

* To change this template file, choose Tools | Templates

* and open the template in the editor.

*/

public class Main {

/**

* "at"param args the command line arguments

*/

public static void main(String[] args) {

// TODO code application logic here

Magzine Obj =new Magzine("Scientific American ", "April", 2020); //object of class

Magzine Obj1 =new Magzine("Scientific American ", "April", 2020);//Obj and obj1 is same content data

Magzine Obj2 =new Magzine("Scientific American", "June", 2020); //obj and obj1 same but obj2 different

 

System.out.println(Obj.toString()); //print string of obj

System.out.println(Obj1.toString());//print string of obj1

System.out.println(Obj2.toString());//print string of obj2

 

 

System.out.println(Obj.equals(Obj1)); //obj and obj1 equal and return true

System.out.println(Obj.equals(Obj2)); // obj and obj2 not equal so return false

 

 

}

 

}
