To introduce another few

methods and practice with them, let's write one more method. Sometimes, when printing an inventory, we

might have long titles $($like the full title of "Make It Stick" $)$ that don't fit in a column width$-$wise. A common trick is to truncate the string

down to a certain length, and replace the end with $""..".$ If the string is below the given length, we leave it alone. So let's

write truncateTitle$(),$ which will take in a length to cut the title down to$,$ and return the truncated title.

class Book $\{$

$\frac{?}{?}**$

@param length The number of characters to appear before $"..."$

@return A new string containing length characters followed by $"..."$ if the

string was too long, or the original string otherwise

$*/$

String truncateTitle$($int length$)\{$

$\}$

$\}$

class ExamplesBook $\{$

Book schemer $=$ new Book$("$The Little Schemer", "Daniel P$.$ Friedman", $40)$;

Book stick $=$ new Book$("$Make It Stick: The Science of Successful Learning", "Peter C$.$ Brown", $13)$;

String truncate$1=$ this.stick.truncateTitle$(15)$;

String truncate $2=$ this.schemer.truncateTitle$(20)$;

String truncate $3=$ this.schemer. truncateTitle$()$;

$\}$

Do Now! Determine the expected output for the following calls to

Fill in the blanks

String truncate$1=$ this.stick.truncateTitle$(15)$; $//$ should be

String truncate$2=$ this.schemer.truncateTitle$(20)$; $//$should be

String truncate $3=$ this.schemer.truncateTitle$()$; $//$should be
