Answer 1

From the Java API:

Reads the next byte of data from the input stream.

What happens is when you type a followed by a newline, there are actually three bytes to read (I'm guessing a followed by carriage return and newline). Hence, the input you provide is enough to keep read() running for three iterations.

I recommend you to use Scanner for input reading instead.
