is there any shortcut way?

easiest way is to just create each object on a new line. I'm sure there are more advanced short ways to do this but at this part of the learning we haven't learned enough to do that. I originally was going to try to do it using a for loop but it wouldn't have worked. So I just went with the newbie approach. Also, try creating all the objects of one type first, then naming all objects of that type, then doing the same for the 2nd and 3rd object types. This was a fun one for me since I've actually played Starcraft a lot and know actual hero names from the game.

Yes there is, instead of creating objects and then adding their names, like this:

Zerg larva = new Zerg();
larva.name = "Larva";
Zerg zergling = new Zerg();
zergling.name = "Zergling";

.. you can write a constructor which will then automatically make object name as a object.name.

I assume what you have done is something on the lines of:

Zerg name1 = new Zerg();
Zerg name2 = new Zerg();
etc

In this circumstance, that's probably the best way to
