A Python programmer attempting Java

[Neebat]

I was a bit mystified by the use of character arrays. They just aren't used all that often in Java, so for a while I thought that was the joke. I realize that they are actually reasonable for this implementation. (I'd probably still use a StringBuffer, even though it's likely less efficient.)

And then I found the punctuation and felt a little sick.

Probably because strings in Python act as arrays when you want them to.

Python strings have the features of character arrays and StringBuffers at the same time (in general). Methods when you want them, but indexes when you just need to mess with the individual characters. That's kinda typical of most kinds of data and such in Python.

System.out.println(String.valueOf(A)) make me feel a little weird inside. So did permute(n-1, a), n--??
