Potential error on page 21 (Sybex)

[Bart Presso]

On page 21 of the OCAJP8, it says:

"Table 1.1 shows the Java primitive types together with their size in bytes and the range of value that each holds."

Shouldn't that be "bits" instead of "bytes"?

Since we don't know which book you are talking about, but anyways, if book mentions 'bytes' in that context', sure, there must be 'bits'.

It's in the OCAJP8 Study Guide by Boyarsky and Selikoff, the book's website (https://www.selikoff.net/java-oca-8-programmer-i-study-guide/) said to post potential errors here :-)

The correct figures are
byte=1, char=2, short=2, int=4, long=8, float=4, double=8, if using bytes.
The correct figures are
byte=8, char=16, short=16, int=32, long=64, float=32, double=64, if using bits.
If using bats, bets, bots, buts or byts, the values are undefined.

[later edit]Yes, that link is the correct place for suspected errors. There are two links on the same website, one for the OCA book and one for the OCP book.

Just checked in the book, Agreed.
