Joining Minecraft servers

I was just playing Minecraft. This was great until I started watching Dan TDM play Skyblocks, and then began the process of chipping away at my parents to buy me the non-edu version so I could join thee servers.

So eventually I got my Minecraft…

But now that it’s purchased and installed, I find that I am unable to join nearly every server I’ve attempted to join. After extensive searching I found a common theme among the responses — and that is references to the java version.

So my question to you Minecraft professionals is this, is there any chance of me getting this version connect to online servers (outside of the “featured” servers that I am able to join without any issue at all), or have I just wasted 40 dollars?
