Recently I’ve rediscovered Class.cast(object) that can be used to cast objects to a type. In Java 8 streams the method allows to do a nice Java casting trick.
In this post we’ll show a practical example of processing tree-like structure using streams and Java 8 flatMap.
There are many ways to create Java Streams and for each of them we’ll show examples. This flexibility is needed especially when combined with flatMap!
Java 8 Comparators with Method References in action. We mix Java 8 static and default methods with method references to sort objects by multiple fields using chained Comparators!
Java 8 Functional Interfaces is very important concept, because they are heavily used with Lambda Expressions and Streams to simplify code. Let’s take a deep dive!
In Java 8 interfaces default and static methods are major changes that allow to extend existing code without breaking anything. It should be the first step into Java 8.
Until Java 7 there was no simple and effective way to generate random numbers concurrently. Here we show ThreadLocalRandom to generate random numbers in a thread-safe way.
Java 8 regular expressions have been improved with names for capturing groups. In this post we show how to used them to improve Java code maintainability!
In Java 8 remove selected item from Collection? It can be done in at least two ways both of which we are going to implement here. Let’s code!
One way to prevent concurrent modifications from different Threads is to given them their own local data. Java ThreadLocal allows to do thread data separation.
