Taboo: java?

That is awesome wtd! On the outside it merely gets input and then outputs it on the screen but on the inside there is much more. I can basically choose the input or output stream I want to use. That could be a file or even the console. I could use something like this for debugging. I could simply choose between input/output from/to a file or regular input from the user and output to the screen. That was one of the most useful things I've learned in a while.
