Attached is a screenshot from Sierra/Bates, Chapter 3, Table 3-3 on Common Wrapper Conversion Methods.

I notice that the 'X' in the rows "byteValue" and "floatValue" are bigger than the 'x' in other rows. Is there a significance to this, or was this a typo (I have access to the earlier version of Sierra/Bates)?

Please help.

I dont think it has any significance. Otherwise the authors would have mentioned it in the legend for the table.

One other thing I just noticed while hand-copying (yes, I've heard that hand-copying notes helps the student understand and retain the information more than copy+paste+print) is there is an 's' on the row "valueOf", column "Boolean".

Please explain how the 's' is different than the 'x'. The only thing explained is that s=static and n=NumberFormatException.

However, the 's' in valueOf row, Boolean column seems to have come out of left field.

Yikes!!!

Bump...

Please let me know if I understood the table correctly. Right now I'm trying to drill in the details of the programming language before I take practice tests again.

It should have been an "x". You can have a look at the Boolean API
 
What's that smell? I think this tiny ad may have stepped in something.
