Functional Java: It’s good to be lazy
Reading Time: 5 minutes In Java, we are often tempted towards writing a code which is executed eagerly. There’s a good reason for that – eager code is easy to write and to reason about. But delaying commitments until the last responsible moment is a good agile practice. When executing the code, we can gain performance by being just a little lazy. In this blog, we will try to Continue Reading
Merge Lists of Map to Map, Java 8 Style!

So, let’s look at the problem and how to solve it. The Problem Well, you guys probably already have guessed what the Continue Reading
Java concurrency: Reentrant Locks
Reading Time: 3 minutes Hello readers! Welcome to another blog in the Java concurrency series. Today, we are going to look at the Reentrant Locks in Java. What it is, how to use it, and mainly, what is the difference between using Reentrant Locks and synchronization. So, let’s dive straight into it. Reentrant Locks Reentrant locks work just like the synchronized locks in java, but have much more facilities Continue Reading

How to deal with Inheritance while using Lombok builder
Reading Time: 2 minutes Today, I came across a problem and found a beautiful solution for it, which is pretty much straight forward, but the problem may occur to anyone while using the Lombok Library for java. So let’s look at the problem. The Problem I have a class Person, which consists of some fields. It is annotated with the @Builder annotation of lombok, so that lombok can generate Continue Reading
Java Concurrency: Thread Confinement
Reading Time: 3 minutes Hello readers! In this blog, we are going to explore about Thread Confinement, what it means and how do we achieve it. So, let’s dive straight into it.
Java Concurrency: Atomic Variables
Reading Time: 3 minutes In today’s blog, we will be discussing and understanding the use of atomic variables with regards to concurrency in Java. But before understanding atomic variables, let’s understand what do we mean by atomic or atomicity.
Basics of Streams In Java8
Reading Time: 2 minutes Streams are introduced in java 8. It is defined in java.util.stream package. A stream is sequence of objects which supports various methods. That can be pipelined to produce the result. Features of Stream Stream is not a data structure. It takes input from various sources (like array, collection, data structure) performs an operation and gives output. It does not store element. It does not change Continue Reading
Guide to Java 8 Concurrency API using Executors
Reading Time: 3 minutes Working with the Thread class in Java can be very tedious and error-prone. Due to this reason, Concurrency API was introduced back in 2004 with the release of Java 5 and then enhanced with every new Java release.The API is located in package java.util.concurrent. It contains a set of classes that make it easier to develop concurrent (multithreaded) applications in Java. The executor services are one of the most Continue Reading
Future vs CompletableFuture in Java- #2
Reading Time: 3 minutes In our previous blog – Future vs CompletableFuture – #1, we compared Java 5’s Future with Java 8’s CompletableFuture on the basis of two categories i.e. manual completion and attaching a callable method. Now, we will be comparing them on the basis of next 3 categories i.e. Combining 2 CompletableFutures together Combining multiple CompletableFutures together Exception Handling Let’s have a look at each one of Continue Reading
Future vs CompletableFuture in Java – #1
Reading Time: 4 minutes This is Part 1 of Future vs CompletableFuture. In this blog we will be comparing Java 5’s Future with Java 8’s CompletableFuture on the basis of two categories i.e. manual completion and attaching a callable method. What is CompletableFuture? CompletableFuture is used for asynchronous programming in Java. Asynchronous programming is a means of writing non-blocking code by running a task on a separate thread than Continue Reading
Rules while working with stream in Java 8
Reading Time: 3 minutes First, let’s have a basic understanding of stream. Then we will have a look at the side effects that can occur while working with streams. Streams represent a sequence of objects from a source, which supports aggregate operations. One thing to be notified while working with streams is that, aggregate operation (intermediate operations) are lazy evaluated i.e. they do not start processing the content of Continue Reading
