Java 2022: Predictions and Assumptions

The need to work from home and the inability to freely move around the world has stimulated the development of data security, cloud computing, big data, tools for remote work. The Java language and platform are still in demand and evolving. In this article, Alex Yelenevych is going to talk about what will influence the development of Java in 2022 and what to expect for developers of this language.

Evolving from a pre-cloud mindset

Evolving Java Runtimes for a Cloud-Centric World

Java runtimes currently operate with a pre-cloud mindset that does not leverage or take advantage of modern cloud environments. Java Virtual Machines (JVMs) can be modernized with new approaches that assume the presence of a “magic cloud.” Cloud-native compilation is a key example of this new approach, with production-ready implementations already producing highly efficient and affordable code optimization.

Interview with Otavio Santana, one of the JNoSQL project leads

Using NoSQL Databases With Jakarta EE and MicroProfile

Otavio Santana, one of the JNoSQL project leads, answered a few questions about the functionality of the Eclipse JNoSQL project – a Java framework that makes it easier to integrate Jakarta EE and MicroProfile applications with NoSQL databases. Learn why Java developers should adopt the technology.

Diagnosing the problem

OutOfMemoryError: Kill Process or Sacrifice Child – Causes and Solutions

This post discusses what triggers this ‘kill Process or sacrifice child’ OutOfMemoryError and potential solutions to diagnose this problem. When processes in the host tend to consume more memory than the available memory in the RAM, Operating System based on its internal heuristics computations will kill certain processes.

Simulate, diagnose, and solve

Chaos Engineering – Stackoverflow Error

This article is part of a tutorial series by Ram Lakshmanan, in which you will learn how to simulate various performance problems. You will learn how to simulate a StackOverflow error, find out how to diagnose it, and most importantly, how to solve the problem.

Avoid these dozen mistakes

Every Java Junior does it: Common Java mistakes made by newcomers

Everyone makes mistakes, not just beginners, but even professionals. This article goes over a dozen common mistakes that Java newbies and newcomers make and how to avoid them. Have you or your colleagues made any of these common Java mistakes early in your career?

Added improvements

Apache Cassandra 4.0: Taming Tail Latencies with Java 16 ZGC

With Apache Cassandra 4.0, you not only get the direct improvements to performance added by the Apache Cassandra committers, you also unlock the ability to take advantage of seven years of improvements in the JVM itself. This article focuses on improvements in Java garbage collection that Cassandra 4.0 coupled with Java 16 offers over Cassandra 3.11 on Java 8.

Automate test writing

How AI (Reinforcement Learning) Can Help Spring Developers Write Better Java Unit Tests

Overall, Java developers love Spring/Spring Boot because it saves them time and supports their testing experiences. The Diffblue Survey found that Spring’s standardized testing approach makes it easier to apply a technique from artificial intelligence (AI) called Reinforcement Learning to automate test-writing. Making this work for Java developers can slash development time as well as improve code coverage.

For Linux and Windows

Quickly find your Java application process ID

For certain monitoring tools like yCrash, you need to pass your application process ID as input. In this article, Ram Lakshmanan will guide you through how to find your Java application process ID in both Linux/Unix and Windows operating systems – simply follow these steps.
