Excursions into Deduplication
For many workloads strings can be the most significant contributor to memory footprint.
When are Strings deduplicated? How can you find out whether they are of any benefit in your application? How much does it cost in terms of CPU?
This article will guide you how to easily find the answers to the questions above.

[JavaSpecialists 270] - Excursions into Deduplication
When are Strings deduplicated? How can we find out whether they are of any benefit in our application? How much does it cost in terms of CPU? We try to show you how we can get this from the deduplication statistics provided by the JVM.
Concurrent programming: Two techniques to avoid shared state
Most certainly the more you learn about multi-threaded programming, the harder it gets. Coordinating multiple threads modifying the same data is complicated. In the following article, you are going to explore two techniques that can help you: Copy before modification and Asynchronous modification using a single thread.

Immutable Collections In Java – Not Now, Not Ever
In JDK terminology, immutable and unmodifiable have shifted over the last few years. At first, the term immutable was used for the collections returned by Java 9’s collection factory methods. But will a method that prints all elements in an immutable collection always have the same output? Yes? No? What’s An Immutable Collection? Is immutability a feature? Can Unmodifiable And Immutable Collections Be Retrofitted? Find out now!

Immutable Collections In Java - Not Now, Not Ever // nipafx
The JDK contains immutable collections, but no type ImmutableCollection. Here's why that's so and why it won't change.
Java, Today and Tomorrow by Mark Reinhold
What’s new in Java today, and what’s coming to Java tomorrow? We’ll start with a review some of the recent additions to the language and the platform. We’ll then look ahead and demonstrate some of the features currently in development in the Amber, Loom, Panama, and Valhalla projects. All of these features will continue to improve both developer productivity and program performance while retaining Java’s core values of readability, generality, and compatibility.
