not always.

When is it not?

When the encoding in use specifies otherwise.

cheers.

If I do

byte[] b = chinese.getBytes( "UTF-8" );

b.length = 6. But why 6 when I thought chinese characters take up 2 bytes
per character?

So chinese characters take up 3 bytes with utf-8 and 2 with 'native
encodings'?? Imagine the extra bandwidth for a chinese server if it uses
UTF-8! +0.5!

Which is why sensible people do not use UTF-8 for Chinese. UTF-8 is
designed to be efficient for text that is mostly ASCII, but sometimes
not. That does not describe Chinese. Use UTF-16.

Whats the main use for
bitwise and bit shifting?

see http://mindprod.com/jgloss/binary.html

Consider the Font.BOLD|Font.ITALIC. It lets you combine binary
attributes.

Quite handy when image processing bitonal images too.

I prefer the experiments personally - those technical manuals are usually
way to wordy

Them's the breaks.

Unless you're patient enough to experiement diligently,
there will probably be cases you haven't considered.

I'm not sure how long you'd have had to experiment
to discover that getBytes is local dependent.
