Spring Boot is an open-source micro framework maintained by a company called Pivotal. It provides Java developers with a platform to get started with an auto configurable production-grade Spring application. With it, developers can get started quickly without losing time on preparing and configuring their Spring application. This post will guide you through understanding what the micro framework is and what it’s used for.

Encountering Java Error 1603 during Java installation can be frustrating, especially when you’re eager to get your software up and running. This is a common, tricky issue that signals a failed installation often due to conflicting software, incomplete previous installs, or insufficient system permissions. Understanding the issue’s root causes and how to tackle them can save time and prevent future headaches.

The addition of the Stream API was a significant enhancement in Java, introducing a powerful way to handle collections with functional-style operations. In Java 9, several improvements were made to this feature, adding more capabilities and refining its functionality. This tutorial will explore both the original Stream API and the enhancements introduced in Java 9, focusing on practical examples to illustrate their usage.

Your Java code was humming along smoothly until... BAM! An exception. No problem, you caught it. But wait, there's another. And another. Suddenly, you're juggling exceptions like you’re in the circus. Don't worry, Java's got your back. Java offers three ways to catch multiple exceptions: using multiple catch blocks for different exception types, the multi-catch feature to handle multiple exceptions in a single block, and a catch-all block for general exception handling.

As one of the most popular programming languages, Java has stood the test of time. The versatile and powerful language has a vast ecosystem and offers numerous advantages and opportunities, whether you’re a beginner or an experienced developer. This post covers Java benefits, various use cases, and why monitoring your Java applications is crucial to application success.

Over the past two and a half decades, Java has consistently been ranked as one of the top 3 most popular programming languages in the world . As a compiled language, any source code written in Java needs to be translated (i.e., compiled) into machine code before it can be executed.

An IllegalStateException is a runtime exception in Java that is thrown to indicate that a method has been invoked at an illegal or inappropriate time. To use an analogy, invoking a method in Java when the system is not in the appropriate state is like trying to start a car while it is in "Drive". Just as the car will not start because it is unsafe, a method call results in an IllegalStateException when the internal conditions necessary for its execution are not met.

Present in every version of Java, the java.lang.RuntimeException is an essential class that allows your application to handle unexpected problems without crashing. Runtime exceptions are exceptions only detected during the execution of your app - things like invalid user input or issues with external resources like files or networks. When an unexpected situation like those occurs, a RuntimeException can be thrown and your app can catch and handle it using a try-catch block.

The IllegalArgumentException is an unchecked exception in Java that is thrown to indicate an illegal or unsuitable argument passed to a method. It is one of the most common exceptions in Java. To illustrate, it's like what happens when trying to set a password in a registration system with specific requirements.

The JSON Web Token (JWT) is an open standard that allows information to be transferred securely between different parties. The token is digitally signed by using a private key (HMAC) or a public/private key (RSA) by building a JSON Web Signature (JWS). It guarantees that the JWT hasn’t been modified since its creation.
