Introduction In Java, concurrency and multithreading are fundamental concepts that facilitate simultaneous execution of two or more parts of a program to maximize the utilization of CPU. The start() method plays a pivotal role in this process. This article delves into the workings of the start() function in Java multithreading, explaining its purpose and significance. Java Multithreading A Brief Overview Multithreading is one of Java's core features, allowing multiple sequences of code, known as threads, to execute concurrently within a single program. By enabling concurrent execution, Java allows more efficient use of CPU resources, particularly on systems with multiple ... Read More

Introduction Java continually evolves to meet modern programming needs, and one of its newest features, Java Records, introduced in JDK 16, simplifies the task of modeling data. This article sheds light on Java Records, detailing how they work alongside constructors and methods to streamline your Java coding experience Understanding Java Records Java Records are a type of class that aims to simplify the representation of "plain data" in your applications. Essentially, they are immutable data carriers used to encapsulate a few final fields, termed 'components', along with methods to access them Before Records, developers had to write a substantial amount ...

Data validation is a critical component of any application development. It ensures that only high-quality data that adheres to predefined standards gets processed. Spring Boot, a renowned framework in the Java ecosystem, offers robust and straightforward validation methods that developers can leverage. This article provides a comprehensive look at how validation is conducted in Spring Boot applications, enabling you to implement these essential techniques effectively. Importance of Data Validation in Spring Boot In Spring Boot, as with any application, data validation is paramount. It involves ensuring that the data received aligns with certain criteria before it's processed. Examples of validation ... Read More

In the world of Object-Oriented Programming (OOP), polymorphism and overriding are key concepts that lend flexibility and dynamism to programming languages. Java, being a robust OOP language, fully supports these features. However, it's crucial to understand that these characteristics apply to methods in Java and not to variables. In this article, we will explore why variables in Java do not follow polymorphism and overriding, providing a deeper understanding of Java's variable behavior. Polymorphism in Java Polymorphism, a Greek word meaning "many forms, " is a fundamental concept of OOP. It allows objects of different types to be treated as objects ... Read More

Java, with its robust object-oriented programming features, offers a multitude of mechanisms for programmers to develop flexible and efficient code. One such concept, often overlooked but critically important, is variance. Understanding variance is crucial for mastering Java, especially when working with generics and collections. This article provides an in-depth exploration of variance in Java, covering its types - covariance, contravariance, and invariance - and their practical applications. Understanding Variance Variance refers to how subtyping between more complex types relates to subtyping between their components. In simpler terms, it determines how the type hierarchy of classes is preserved when these classes ... Read More

Java is a statically-typed language known for its verbosity and strict type checking. However, with the release of Java 10, a new feature called Local-Variable Type Inference was introduced, bringing the var keyword to the language and changing the way Java developers code. This article will explore the var keyword, illustrating its use cases and discussing its implications for Java coding practices. Understanding 'var' in Java In Java, traditionally, we needed to explicitly declare the type of every variable we created. With the introduction of var in Java 10, this has changed. The var keyword allows you to declare ... Read More
