Exam 1Z0-817: Upgrade OCP Java 6, 7 & 8 to Java SE 11 Developer Study Guide

Exam Topics

1. ​Understanding Modules​

   • Describe the Modular JDK​
   • ​Declare modules and enable access between modules​
   • ​Describe how a modular project is compiled and run​

2. Services in a Modular Application

   • Describe the components of Services including directives
   • Design a service type, load the services using ServiceLoader, check for dependencies of the services including consumer module and provider module

3. Java Interfaces

   • Create and use methods in interfaces
   • Define and write functional interfaces

4. Lambda Operations on Streams

   • Extract stream data using map, peek and flatMap methods
   • Search stream data using search findFirst, findAny, anyMatch, allMatch and noneMatch methods
   • Use the Optional class
   • Perform calculations using count, max, min, average and sum stream operations
   • Sort a collection using lambda expressions
   • Use Collectors with streams, including the groupingBy and partitioningBy operation

5. Java File I/O (NIO.2)

   • Use Path interface to operate on file and directory paths
   • Use Files class to check, delete, copy or move a file or directory
   • Use Stream API with Files

6. Migration to a Modular Application

   • Migrate the application developed using a Java version prior to SE 9 to SE 11 including top-down and bottom-up migration, splitting a Java SE 8 application into modules for migration
   • Use jdeps to determine dependencies and identify way to address the cyclic dependencies

7. Local-Variable Type Inference

   • Use local-variable type inference
   • Create and use lambda expressions with local-variable type inferred parameters

8. Lambda Expressions

   • Create and use lambda expressions
   • Use lambda expressions and method references
   • Use built-in functional interfaces including Predicate, Consumer, Function, and Supplier
   • Use primitive and binary variations of base interfaces of java.util.function package

9. Parallel Streams

   • Develop the code that use parallel streams
   • Implement decomposition and reduction with streams

10. Language Enhancements

    • Use try-with-resources construct
    • Develop code that handles multiple Exception types in a single catch block
