Create a new class named URLWrapper with the following:

$1.$ Two private data members: final URL url and int count.

$3.$ Getter methods for private data members:

protected URL getURL$()$

protected int getCount$()$

$4.$ The findCount method finds the number of occurrences of the user$-$specified search keyword in the HTML file.

$$ Set up buffered reader.

$$ Read from URL and count the number of occurrences of keyword.

$$ protected void findCount$($String key$)$

$5.$ The extractInnerURL method gets inner URLs.

For the inner links, may use the regular expression: "href$=\backslash "(($http$|$https$)$:$\backslash \backslash /\backslash \backslash /.*)\backslash ""$

protected ArrayList extractInnerURLS$($String key$)$

Procedures:

$1.$ Get input from the user: base URL and search keyword from the console.

$2.$ Get the total occurrence of search keyword for base URL.

$3.$ Get inner URLs.

$4.$ Get the total occurrence of search keyword for each inner URL.
