Jump to level $1$

The Book class has a default constructor with no parameters. Define a public overloaded constructor that takes two string parameters and initializes the book's title and author with the strings.

Ex: If the input is Gold Cook, then the output is:

Book: None, None

Book: Gold, Cook

Library.java

public class Book $\{$

private String title;

private String author;

public Book$()\{//$ Default constructor

title $=$ "None";

$\}$

author $=$ "None";

V$*$ Your code goes here $*/$

public void print$()\{$

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

$\}$
