Do google index 2nd depth links of my site? Help Needed !!

Hi everyone, i have got a small doubt. I have a site like http://www.example.com.

It is main page. So, i have a category, like some example in it. So google also indexed it. So think page url : http://www.example.com/example.html.

So, will the google index also the inner pages of example.html. I have some two to three small categories in example.html page also. Think like example 1 and example 2 html files are there in example.html page.

So, will the google index those example 1 and example 2 also?

 

Still looking for response, will the google crawl inner and inner pages also?
