Question

JAVA

This PoD, builds off the Book class that you created on Monday (you may copy your previously used code). For today’s problem, you will add a new method to the class called lastName() that will print the last name of the author (you can assume there are only two names in the author name – first and last). You can use the String spilt (“\s”) method that will split the String by the space and will return an array of Strings. Only return the last name (a String).

Here is the updated Book Class:
• author (String)
• title (String)
• year (int)
• price (double)

and the following methods:
• Constructor (that sets the author, title, year, and price from defined values).
• Get and set methods.
• toString method returns the title, author and year of the book
• lastName() which returns a String that represents the last name of the author.

Then create a BookDemo class to create and use Book objects. The BookDemo class contains the main method. Use a Scanner object to read the attributes for a Book object. Create a Book object by passing in the attributes read in by the Scanner object. Then call the toString method and then call and print the lastName() method.

Details

Note: Since the author and title can be more than one word, use the Scanner object to read in author and title on different lines, and the year and price on the same line.

Input

An author, input in the following format:
{First Name} {Last Name}
{Title}
{Year Published}

Example Input:
Margaret Atwood
The Handmaid’s Tale
1987 22.99

Output

Print using the toString method, then print only the last name.

Example Output:
The Handmaid’s Tale by Margaret Atwood, 1987
Atwood
