OCPJP 8 Upgrade (All Versions) Exam Information

The OCPJP 8 Upgrade (All Versions) - (Oracle Certified Professional, Java SE 8 Programmer (Java SE 6 and all prior versions)) certification improves object-orientated programming and Java fundamental skills. This https://www.epractizelabs.com/oracle/java-certifications/ also tests Java SE 8 new features such as 'Lambda expressions', 'Streams', 'Concurrenyc' and 'Date and Time API'. As Java Language Specification has been updated for these new features, the experienced Java developers also need to learn the new style of coding by preparing for this exam.

Few important changes of Java SE 8 are:

Lambda Expressions, a new language feature, has been introduced in this release. They enable you to treat functionality as a method argument, or code as data. Lambda expressions let you express instances of single-method interfaces (referred to as functional interfaces) more compactly.

Method references provide easy-to-read lambda expressions for methods that already have a name.

Default methods enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces

Classes in the new java.util.stream package provide a Stream API to support functional-style operations on streams of elements. The Stream API is integrated into the Collections API, which enables bulk operations on collections, such as sequential or parallel map-reduce transformations.

Classes and interfaces have been added to the java.util.concurrent package.

Methods have been added to the java.util.concurrent.ConcurrentHashMap class to support aggregate operations based on the newly added streams facility and lambda expressions.

Classes have been added to the java.util.concurrent.atomic package to support scalable updatable variables.

Methods have been added to the java.util.concurrent.ForkJoinPool class to support a common pool.

The java.util.concurrent.locks.StampedLock class has been added to provide a capability-based lock with three modes for controlling read/write access.

OCPJP 8 Upgrade (All Versions) Sample Question

The following practice question is taken from MyExamCloud OCPJP 8 Upgrade (All Versions) Study Plan.

Given:

1. import java.util.HashMap;
2. import java.util.Map;
3. import java.util.function.BiConsumer;
4. import java.util.function.BiFunction;
5.
6. public class MyExamCloud{
7. public static void main(String[] args){
8.
9. Map numbers = new HashMap();
10. Map numbers2 = new HashMap();
11. numbers.put(1, "one");
12. numbers.put(2, "Two");
13. numbers2.put(3, "Three");
14. numbers2.put(4, "Four");
15.
16. BiFunction func = (k,v) -> v;
17.
18. BiConsumer cons = (k,v) -> numbers.merge(k, v, func);
19. numbers2.forEach(cons);
20. System.out.println(numbers);
21. }
22. }

What is the output?

Choices

Choice A:

{1=one, 2=Two, 3=Three, 4=Four}

Choice B:

{1=one, 2=Two}

Choice C:

{3=Three, 4=Four}

Choice D:

Compilation fails due to error at line 16

Choice E:

Compilation fails due to error at line 18

Answer and Explanation:

Choice  A is correct

From Java SE 1.8, we have a new method called merge that can use to merge two maps together.
default V merge(K key, V value, BiFunction remappingFunction)

If the specified key is not already associated with a value or is associated with null, associates it with the given non-null value. Otherwise, replaces the associated value with the results of the given remapping function, or removes if the result is null.

In give code we have created Function instance and a BiConsumer using that Function. At line 19, invoking forEach method by passing the BiConsumer will merge the numbers map to numbers2 map.

Exam Objective: Java File I/O (NIO.2) - Use Stream API with NIO.2
