Presentations
Beyond Managing Your Manager
This is a revised and updated version of the previous talk, with current thinking from practice and the literature. The talk presents why conflicts with your manager are inevitable based on differences in priorities and perspectives, and how to plan for them. The goal is to show you how to build the loyalty relationship that allows you to get what you need when you need it.
Functional Java, Part 1
Understand Java from a functional programming point of view. This part covers the basics of lambdas and streams, emphasizing functional programming by transforming collections using the stream approach.
Functional Java, Part 2
Functional features in Java, including parallel streams, the java.util.function package, the Optional data type, and reduction operations.
Refactoring to Java 8
Java SE 8 introduces many new features that can simplify your code. Using streams, lambdas, and the new Optional type all change the way we write Java. In this presentation, we'll work through a series of examples that show how to rewrite existing code from Java 7 or earlier using the new Java 8 approach.
Special Topics In Java
This talk will focus on interesting features of Java 8 that go beyond the basics. Topics will include:
- the
map,filter, andflatMapmethods - simple reductions
- extracting and combining streams
- using
Optionalas intended - grouping and partitioning
- downstream collectors
- the
java.timepackage - generics in detail
Parallel Streams, Completable Futures, And All That
This talk covers the concurrency and parallelization options in Java 8 and above. Topics include: the difference between concurrency and parallelization, the stream model in Java, using parallel streams, measuring performance, the CompletableFuture class, coordinating futures, and more.
Latest Features In Java
Java is now on a six-month release schedule, with new features being added all the time. This talk summarizes the features that have been added to Java, including collection factory methods, private methods in interfaces, records, the enhanced switch statement, and more. The goal is to show not only what has been added, but why and where to use them.
