Introduction to the AWS CDK Using Java and Maven

This is the first video of the AWS CDK (Cloud Development Kit) with Java series. We’re covering the following topics:

• install the AWS CDK CLI
• bootstrap a Java-based CDK app
• explore the basic commands of the CDK CLI to deploy our app

AWS CDK Developer Guide: https://docs.aws.amazon.com/cdk/latest/guide/home.html

More information on how to configure your AWS credentials and region: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-files.html

You can find the source code for this example on GitHub: https://github.com/rieckpil/blog-tutorials/tree/master/aws-cdk-java-introduction

» As part of the Stratospheric book (From Zero To Production with Spring Boot and AWS), we’re using the AWS CDK to deploy a production-ready AWS infrastructure. Make sure to grab your copy here https://stratospheric.dev/

How to Install OpenJDK 11 on CentOS 8

What is OpenJDK?

OpenJDk or Open Java Development Kit is a free, open-source framework of the Java Platform, Standard Edition (or Java SE). It contains the virtual machine, the Java Class Library, and the Java compiler. The difference between the Oracle OpenJDK and Oracle JDK is that OpenJDK is a source code reference point for the open-source model. Simultaneously, the Oracle JDK is a continuation or advanced model of the OpenJDK, which is not open source and requires a license to use.

In this article, we will be installing OpenJDK on Centos 8.

Going Beyond Java 8: Local Variable Type Inference (var) - DZone Java

According to some surveys, such as JetBrains’s great survey, Java 8 is currently the most used version of Java, despite being a 2014 release.

What you are reading is one in a series of articles titled ‘Going beyond Java 8,’ inspired by the contents of my book, Java for Aliens. These articles will guide you step-by-step through the most important features introduced to the language, starting from version 9. The aim is to make you aware of how important it is to move forward from Java 8, explaining the enormous advantages that the latest versions of the language offer.

In this article, we will talk about the most important new feature introduced with Java 10. Officially called local variable type inference, this feature is better known as the **introduction of the word **var. Despite the complicated name, it is actually quite a simple feature to use. However, some observations need to be made before we can see the impact that the introduction of the word var has on other pre-existing characteristics.

What is Assertion in Java? How to use Assertion in Java

Table of Contents

What is Assertion in Java?

The assertion in Java is used to ensure the correctness of any program’s assumptions as the assertion is assumed to be true when it is executed. The Java Virtual Machine throws an error named AssertionError if the assertion is false. The assertion in Java has found its application mainly for testing purposes. Boolean expressions are used along with assertion statements. An assertion is a statement, and the ‘asset’ keyword is used to carry out an assertion in Java.

Introduction to JAVA COLLECTIONS

In this blog we will understand basics of JAVA Collections framework.

What are JAVA Collections and Why do we need them?

The Collection in Java is a framework that provides an architecture to store and manipulate the group of objects.

Collections are like containers that group multiple items in a single unit. For example, a jar of chocolates, a list of names, etc. Collections are used in every programming language and when Java arrived, it also came with few. Let’s see how does it help us:

  • Reduces programming effort
  • Increases program speed and quality
  • Allows interoperability among unrelated APIs
  • Reduces effort to learn and to use new APIs
  • Reduces effort to design new APIs
  • Fosters software reuse
