Who created MyExamCloud OCPJP 8 Upgrade Practice Tests?
The OCPJP 8 Upgrade Practice Questions and study notes are created by highly qualified and Java Certified experts. The Authors has created this online course covering all Upgrade Java SE 7 to Java SE 8 OCP Programmer exam objectives based on latest Oracle's changes.
Exam Process
The OCPJP 8 Upgrade - (Oracle Certified Professional, Java SE 8 Programmer (upgrade)) certification improves object-orientated programming and Java fundamental skills. This Java Certification 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 Sample Question
The following practice question is taken from MyExamCloud OCPJP 8 Upgrade Study Plan.
Consider following:
Runnable r = new Runnable(){
public void run(){
System.out.println("epractizelabs.com");
}
};
Which of the following is equivalent for above code fragment?
Choices
Choice A:
Runnable r = new Runnable(){ () -> System.out.println("epractizelabs.com")};
Choice B:
Runnable r = -> System.out.println("epractizelabs.com");
Choice C:
Runnable r = () -> System.out.println("epractizelabs.com");
Choice D:
Runnable r = -> () System.out.println("epractizelabs.com");
Choice E:
Runnable r = () {-> System.out.println("epractizelabs.com")};
|
Answer and Explanation:
Choice C is correct
Here we use lambda expression for Runnable interface. A lambda expression is composed of three parts
- Argument List
- Arrow Token
- Body
The body can be either a single expression or a statement block. In the expression form, the body is simply evaluated and returned. In the block form, the body is evaluated like a method body and a return statement returns control to the caller of the anonymous method.
Option C is correct as it is the only statement which follows correct format as explained above.
Exam Objective: Lambda Expressions - Describe a Lambda expression; re-factor the code that use anonymous inner class to use Lambda expression; including type inference, target typing
