Given the code fragment:

Which should be inserted into the line n1 to print Average = 2.5?

Stream str = Stream.of(1, 2, 3, 4);
IntStream str = IntStream.of(1, 2, 3, 4);
DoubleStream str = Stream.of(1.0, 2.0, 3.0, 4.0);
IntStream str = Stream.of(1, 2, 3, 4)

Correct answer: B

Explanation:

Use IntStream. Reference: https://docs.oracle.com/javase/8/docs/api/java/util/stream/IntStream.html

Given the interface:

Which class implements IdGenerator in a thread-safe manner, so that no threats can get a duplicate id value during concurrent access?

Correct answer: B

Explanation:

An AtomicInteger is used in applications such as atomically incremented counters, and cannot be used as a replacement for an Integer. However, this class does extend Number to allow uniform access by tools and utilities that deal with numerically-based classes. The incrementAndGet() method atomically increments by one the current value. Reference: http://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicInteger.html#incrementAndGet--

Which two statements are true about localizing an application? (Choose two.)

Language codes use lowercase and region codes use uppercase letters.
Resource bundle files include date and currency information.
Language and region-specific programs are created using localized data.
Support for new regional languages does not require recompilation of the code.
Textual elements (messages and GUI labels) are hard-coded on the code.

Correct answer: AC

Explanation:

A: The following examples create Locale objects for the French language in Canada, the English language in the U.S. and Great Britain.aLocale = new Locale("fr", "CA"); bLocale = new Locale("en", "US"); cLocale = new Locale("en", "GB"); C: Localization is the process of adapting an internationalized application to support a specific region or locale.Incorrect Answers:B: Resource bundle files does not include date a currency information. Date and currency information are stored in locales, not in resource bundle files.D: Recompilation is not necessary.E: Textual elements are not hard-coded on the code.References:https://docs.oracle.com/javase/tutorial/i18n/locale/create.htmlhttp://docs.oracle.com/javaee/6/tutorial/doc/bnaxw.html
