Whoops! Posted in wrong forum. I've reposted in the OCPJP forum. Please ignore.

Hi,
I have some questions on various points in the Sybex OCP8 study guide. I don't know if it's my own misunderstanding that's the problem or if it's the wording of the text. Any help would be appreciated.

p84. In the bottom paragraph. 'We provide two methods for retrieving the total number of favorite foods as
well as a method to retrieve a food based on an index value.'
To me that sounds like 3 methods altogether but I think there are only 2 that are relevant. Should it be rewritten for clarity?

p359 - I'm puzzled by the third sentence - 'As you may remember from our discussion of polymorphism in Chapter 2, even though the reference type changes, the underlying object is still a ConcurrentHashMap.' But in the examples above, the reference type hasn't changed and the object has.

p377. In the third sentence in the box (starting with 'Alternatively') the end doesn't seem to match up with the start. Are there some words missing?

p463 - first sentence. What is a 'path representative'? Does 'representative' have a specific meaning in Java that I've not come across before?

p476 - middle of the page 'the NIO.2 API bridges information about streams,'. What does this phrase mean?

Thanks,
Nick.
Hi,
I've spotted a few more minor typos for the errata list.

p178 - In the middle of the box, the italicised 'eggs' should just be 'egg'.

p208 - 5th line, 'this function that takes an Object' should have 'that' removed.

p334 - halfway down, my old English teacher wouldn't like 'requests the current thread of execution rest'. It could be either 'requests that the current thread of execution rest' or 'requests the current thread of execution to rest'. I'm English, and American English grammar may not be as strict so you could disagree on this one.

p358 - near the bottom 'in own custom implementation'? Should this be 'in our own custom implementations'?

p358 - same sentence as above. 'forgot' is a tense change within the sentence, which my English teacher also wouldn't like, so 'forget' would be better.

p373 -  last sentence - 'Recall that' should be 'Recall that the'.

p377 - First sentence in box - 'a parallel' should just be 'parallel'.

p551 - Q9. 'and as the code would not compile'. I think the 'as' is superfluous here, or maybe it should be 'so'.

Regards,
Nick.

Hi, first post.
I've made it all the way through the Sybex OCP Java 8 Study Guide.
Overall I like it and I expect most of my questions will be answered by another readthrough.
However, I noticed a few typos that I haven't seen in the errata.

page 219 - Third paragraph. Shouldn't it be 'implementation of Set' not 'implement of Set'?
page 233 - First Localisation bullet point. Shouldn't it be "set the locale" instead of "set the local"?
page 287 - Table 6.3 Reference to Chapter 3 for DateTimeException should be Chapter 5.
page 298 - 2nd last comment line in code example. "exeption handler" should be "exception handler".
page 306 - First paragraph. Shouldn't it be "There are a few" not "There are few"?
page 428 - First sentence after the box. Is there any need for the 'a' before Serializable?
page 637 - "Too be determined"? I know it's in a String and it will print perfectly well. It just bugs me. Should be "To be".
page 648 - The very last page. There's a reference to Option H which does not exist. Should be Option G.

Now back to page 1 for me for another try.
Nick.
