Do I need to add a try$-$catch block to throw the FileNotFoundException in this code? If so$,$ what would the finished, compilable code for MyCat.java look like?

package cs$1302.$exceptions;

import java.util.Scanner;

import java.io$.$File;

import java.io$.$FileNotFoundException;

$/**$

$*$ A simpler version of the Unix cat command.

public class MyCat $\{$
