Explore Java Stream.of() Method

Java Streams provide a powerful and expressive way to process data collections in a functional style. The Stream.of() method is a fundamental part of the Java Stream API, allowing you to create streams from individual elements or arrays.

Master Singleton Classes in Java

Singleton classes are a fundamental design pattern in Java, used when you want to ensure that a class has only one instance and provide a global point of access to that instance. This pattern is invaluable when precisely one object is needed to coordinate actions across the system, such as a configuration manager, thread pool, or database connection. In this guide, we will explore various ways to create singleton classes in Java.

Guide to Create Immutable Classes in Java

In Java, immutability is a key concept in object-oriented programming. An immutable class is one whose state cannot be modified after it has been created. Immutable classes provide numerous benefits, including thread safety, ease of use, and robustness in concurrent programming. In this guide, we will explore the principles of creating immutable classes in Java and demonstrate step-by-step how to implement them effectively.

Guide to Java 8 IntStream

Java 8 introduced the Stream API, which revolutionized the way we work with collections in Java. Among the various stream types, IntStream is a specialized stream that deals exclusively with primitive int values. In this comprehensive guide, we will take a deep dive into IntStream, exploring its features, use cases, and how to harness its power in your Java applications.

Guide to Java 8 Stream.reduce() method

In the world of Java programming, Java 8 introduced the Stream API, which revolutionized the way we work with collections. Among the numerous features Stream offers, the reduce() method stands out as a powerful tool for performing aggregation operations on a stream of elements. This method allows you to perform operations such as summing, multiplying, finding the maximum or minimum, and more, with ease and elegance. In this article, we’ll dive deep into the world of Stream.reduce(), exploring its syntax, common use cases, and best practices.

Mastering Google Guava Multimap for Efficient Data Grouping

Google Guava is a powerful library that complements the Java Standard Library with additional utilities and data structures. One such versatile data structure provided by Guava is the Multimap. In this comprehensive guide, we will explore what a Multimap is, its use cases, and how to effectively utilize it in your Java applications.

Arrays.aslist() and UnsupportedOperationException

UnsupportedOperationException is a member of Java Collection Framework, it’s thrown when an operation cannot be performed because it is not supported for that particular collection.

One of the most common causes for this exception is using the Arrays.asList() method, Let’s dive into the source codes and figure out why this could happen.
