Hi Friend,

Try the following code:

import java.util.*;

 class Book{
    int id;
    String title;
    String author;
    double price;


    public void setId(int id){
        this.id=id;
    }
    public int getId(){
        return id;
    }

    public void setTitle(String title){
        this.title=title;
    }
    public String getTitle(){
        return title;
    }

    public void setAuthor(String author){
        this.author=author;
    }
    public String getAuthor(){
        return author;
    }

    public void setPrice(double price){
        this.price=price;
    }
    public double getPrice(){
        return price;
    }
}
class Periodical
{
    String timeperiod;
    public void setTimeperiod(String timeperiod){
        this.timeperiod=timeperiod;
    }

    public String getTimeperiod(){
        return timeperiod;
    }
}
public class BookInformation{
    public static void main(String[]args){
        Book b=new Book();
        Periodical p=new Periodical();
        Scanner input=new Scanner(System.in);
        System.out.print("Book ID: ");
        int id=input.nextInt();
        b.setId(id);
        System.out.print("Title: ");
        String  title=input.next();
        b.setTitle(title);
        System.out.print("Author: ");
        String  author=input.next();
        b.setAuthor(author);
        System.out.print("Price: ");
        double  price=input.nextDouble();
        b.setPrice(price);

        System.out.print("Period: ");
        String  pp=input.next();
        p.setTimeperiod(pp);
System.out.println();
System.out.println("----Book Information----");
System.out.println();
System.out.println("Book ID: "+b.getId());
System.out.println("Title: "+b.getTitle());
System.out.println("Author: "+b.getAuthor());
System.out.println("Price: "+b.getPrice());
System.out.println("Period: "+p.getTimeperiod());
    }   
}
