Provide instance fields for title, month, and year (for example, "Scientific American", "April", 2020). Each of these should be accessible only within the Magazine class. Create a constructor, which initializes the instance fieldsWrite a toString() method, modeled after the standard Java toString() method, to return a String representation of the Magazine. Write an equals() method, modeled after the standard Java equals() method. Two Magazines are equal if they have the same title, month, and year. HTML EditorKeyboard Shortcuts

Explanation:

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

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

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;

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
