    • Implement overloading, including var-arg methods
    • Understand variable scopes, apply encapsulation, and make objects immutable.
    • Use local variable type inference, including using it to define lambda parameters
    • Implement inheritance, including abstract and sealed classes.
    • Override methods, including that of an Object class.
    • Utilize polymorphism and type casting, and differentiate object type versus reference type.
    • Identify object types using instanceof operator and pattern matching

    • Create Java arrays, List, Set, Map and Deque collections, and produce, remove, update, retrieve and sort their elements
  • Working with Streams and Lambda expressions
    • Use Java object and primitive Streams, including lambda expressions implementing functional interfaces, to produce, filter, transform, consume, and sort data
    • Perform decomposition, concatenation and reduction, and grouping and partitioning on sequential and parallel streams
  • Package and deploy Java code and use the Java Platform Module System
    • Define modules and expose module content including through the use of reflection, and declare module dependencies, define services, providers and consumers
    • Compile Java code, produce modular and non-modular jars, runtime images, and implement migration using unnamed and automatic modules
  • Manage concurrent code execution
    • Create worker threads using Runnable and Callable, manage the thread lifecycle, including automations provided by different Executor services and concurrent API
    • Develop thread-safe code, using different locking mechanisms and concurrent API
    • Process Java collections concurrently and utilise parallel streams.
  • Use Java I/O API
    • Read and write console and file data using I/O Streams

  • Implement Localization
    • Implement localization using locales, resource bundles, parse and format messages, dates, times, and numbers including currency and percentage values

Recommended books

1z0-829 exam

When it was available, we will also use this book for the 1z0-829 exam and this one for the mock tests.

1z0-819 exam

We want to use this book OCP Oracle Certified Professional Java SE 11 Developer Complete Study Guide: Exam 1Z0-815 and Exam 1Z0-816. It can be used also for the Upgrade Exam 1Z0-817.
