Consider the code:

public class Book $\{$

private String title;

private String author;

public Book$($String title, String author$)\{$

this.title $=$ title;

this.author $=$ author;

$\}$

public void printBookDetails$()\{$

System.out.println$("$Title: $"+$ title $+",$ Author: $"+$ author$)$;

$\}$

public void saveToDatabase$()\{$

$//$ Code to save the book details to a database

$\}$

$\}$

Which modification adheres to the Single Responsibility Principle?

Question $1$Answer

a$.$

Move printBookDetails$()$ method into a BookPrinter class

b$.$

Combine the printBookDetails$()$ and saveToDatabase$()$ methods into one

c$.$

Add another method to handle the saving and printing functionality in a single call

d$.$

The class already obeys Single Responsibility Principle, no change is needed
