Errata

O bought the book at Amazon Kindle Store and this version has not page numbers. The issue is minimal, it is a little typo for the word 'readbility', where it should be readability.

Note from the Author or Editor:
Thanks for spotting this issue - I will have the typo fixed.

The example is: Predicate<Integer> atLeast5 = x -> x > 5; though it compiles, the variable name is "wrong": it should be "atLeast6" or "greaterThan5" or something similar

Note from the Author or Editor:
Fixed.

It says: Operator '+' cannot be applied to java.lang.Object, java.lang.Object. but it should be: Operator '+' cannot be applied to java.lang.Object, java.lang.Object.

Note from the Author or Editor:
Fixed.

Under point b., it says "DateFormatter" twice, this should be DateFormat (since it refers to java.text.DateFormat)

Note from the Author or Editor:
Fixed, though again its a typo.

In Example 3-3 on page 19 of the printed book, the description says "Counting Liverpool-based artists using internal iteration", but the example contains the code: .filter(artist -> artist.isFrom("London")) where as previous examples (3-1 and 3-2) correctly use isFrom("Liverpool").

Note from the Author or Editor:
This is correct, it should say isFrom("Liverpool")

Example 3-6 says: "artist.isFrom("London");" Then the text and Example 3-7 use The Beatles as an example of what would be printed. This is wrong, in the sense that The Beatles are from Liverpool. So either Example 3-6 should be changed to use Liverpool. Or the following text & Example 3-7 should be changed to use a London-based band instead, like e.g. The Rolling Stones.

Note from the Author or Editor:
Fair point, fixed.

It starts by taking a Stream from a List should be It starts by taking a Stream from an Array

Note from the Author or Editor:
Thanks for spotting this - it is a mistaken description.

While describing Example 3-13, the text says: In this case we’ll use length, which is a getter function in disguise. Since the concerned code is: Comparator.comparing(track -> track.getLength()) I don't understand: - why the text doesn't say "getLength" instead of "length" - why it says it's a getter function "in disguise", since it really is just a getter function

Note from the Author or Editor:
Valid error, but really a typo in the text. Fixed.

The text says: The calls to musicians, filter, and map all return Stream objects, [...] I think "musicians" should be replaced with "getMusicians"

Note from the Author or Editor:
Fixed.

forEach(musicain -> count.incAndGet();) should be forEach(musicain -> count.incrementAndGet());

Note from the Author or Editor:
Thanks for reporting this error. I've fixed it in my repository and any future update will include a fix for this issue.

The text says: "A BinaryOperator is special type of BiFunction" I think there should be an extra "a" after "is": "A BinaryOperator is a special type of BiFunction"

Note from the Author or Editor:
Fixed.

The text says: "If there is a single possible target type, the lambda expression infers the type from the corresponding argument on the functional interface." while I think it should read: "[...] from the corresponding parameter of the functional interface method."

Note from the Author or Editor:
Certainly better wording.

The text says: "In this case, what we’re really trying to do is perform a map operation on the list from the Artist to the album name." while it should say (Artist should be replaced with Album): "[...] from the Album to the album name."

Note from the Author or Editor:
Fixed.

"closey" should be "closely"

Note from the Author or Editor:
Fixed.

The method "simulateDiceRoles" (and its invocation) should be changed to "simulateDiceRolls" instead.

Note from the Author or Editor:
Fixed.

The text says: "Unfortunately, reality can get the way of the ideal at times!" but there's an "in" missing: "[...] can get in the way [...]"

Note from the Author or Editor:
Valid errata, fixed in git repo.

Change the method name from "imperativeInitilize" (missing "a") to "imperativeInitialize"

Note from the Author or Editor:
Valid errata, fixed in git repo.

The text says: "Let’s take look Example 7-8" This should be: "Let's take a look at Example 7-8"

Note from the Author or Editor:
Valid issue, fixed in git repo.

The text says: "This can be become a performance limitation" It should be something like the following instead: "This can become ..." "This can be ..." "This can be, or become, ..." ...

Note from the Author or Editor:
Fixed in git repo.
