extracting the links of a treet

its fine to create that getExternalLinks method as an objective but does it really work in our treet example? Because we split our String with the regular expression but there are also points, colons where we split. We can't use the getWords()-method because we split the links too or we need to optimize our regEx? If we add . : / - to our regular expression than we have another problem because we dont get proper words either. My english is not the best, hopefully you can understand my point.

Hi Alexander!

The getWords method we wrote on the BlogPost is different. It works on spaces instead of special cases. Good point though, we'd have to rethink for our Treets, good thing we have all that logic encapsulated in methods!

Also, awesome English man!

thank you :), awesome course so far! I know most of the containers from the c++ standard library and it is pretty cool to adapt that knowledge but the concept of interfaces and implementations is kind of new to me. I was used to references in c++. Hopefully i will get my head around that and feeling more comfortable with them soon.
