Cast to a Treet (?)

Hello there, Im wondering if you can explain to me the meaning "cast to a treet", well Craig said that in min 07:34 in Interfaces (java)

Is this "cast to a Treet" the same as converting a String that is given as a parameter within the method to an Object?

I mean, I'm seeing it this way. I write a String, the method receives that String as a parameter and the casting "converts" that String into an object? Is that it?

Im sorry but english is my second language and I'm finding myself lost understanding the "cast" word.

Hi Miguel,

with casting you kind of force a variable into a new type. The new type has to be compatible with the old one or you'll get a ClassCastException. It's a rather complex topic. I recommend this article.

Kind Regards, Florian
