The Predicates — In the previous articles(Part-2, and Part-3, we have seen Consumer and BiConsumer functional interfaces. In this article, we will see another important functional interface which is the Predicate. Note: Please stick on to it till the end as I have a pro-tip in using Predicates and one important interview question…

The BiConsumer — In the last part, we have seen one of the functional interfaces the Consumer. In this article, we look at the other variant of it — The BiConsumer. We have seen that in the Consumer interface there is this abstract method accept(T t) with only one argument. And we also…

The annotation @FunctionalInterface and the Consumer interface — In the last part, we have seen how to transform the anonymous inner classes into lambda expressions. In this article, we will see several functional interfaces. With Java 8 release, there were several functional interfaces introduced. We can find them in the JDK source code as they are annotated with…

Introduction to Functional Programming I don’t wanna get you, my readers, bored by specifying all the history of Java with its immense Object-Oriented Paradigm capabilities which, of course, later evolved as one of the Functional Programming languages and etc. But there was a phase at which it couldn’t compete with…

Your One-Stop Multithreading and Concurrency Guide This article contains all the articles in the series Java Multithreading, Concurrency, and Parallelism in the TOC style.

Parallel Streams and the Async Programming with CompletableFuture In the previous article, we have seen the internal details of the Fork/Join framework. In this article, we will see the two most important constructs that are built based on the Fork/Join framework: The Parallel Streams and the CompletableFutures. Note: This article…

Understanding the ForkJoinPool and Workstealing In the previous article, we have seen how to implement parallel processing using ForkJoinPool. In this article, we will go to the depths of ForkJoinPool and how the work-stealing happens behind the scenes. As a quick recap of what we have seen in the previous…

The Fork-Join Pool Implementation In the previous article, we introduced Parallelism and the Fork/Join framework. In this article, we will take the same big sum computation problem and solve it using the Fork/Join framework. Let us first look at the flow of what we need to do in order to…

Introduction to Parallesim — Fork-Join Framework We have seen the different ExecutorService instances like Fixed Thread Pools, Cached Thread Pools, Scheduled Thread Pools, and Single Thread Pools. All these ExecutorsService objects are centered around the concept of Separation of Concerns — Decoupling the Task Submission from its Execution. If you…
