InterruptedException e

I'm reading about InterruptedException because I'm dealing with threads, and I'm wondering is the catch (InterruptedException e) a special case because there is an e there?

I've seen ie, but unfortunately I can't seem to find any webpage that tells me what the letters after InterruptedException do.

Are there different InterruptedExceptions?

That is just an name for your exception object. You can have "kokoobananas" in place of "e" :). Just make sure you use kokoobananas.printStackTrace()

It is irrelevant. It is just a variable name. You can name the exception anything.

catch(Exception someVariableNameYouChoose)

No, they're not. The e or ie after InterruptedException is just the name of the variable where the exception raised will be caught.

This piece of code:

try {
} catch (InterruptedException e) {
    e.printStackTrace();
}

And

try {
} catch (InterruptedException ie) {
    ie.printStackTrace();
}

Are basically the same. The only difference is the name of the variable, the former declares it as e while the latter declares it as ie.
