As a Java developer, I've found that design patterns are indispensable tools for creating robust and maintainable software. They provide proven solutions to common programming challenges and help us write cleaner, more efficient code. In this article, I'll share my insights on seven essential Java design patterns that have significantly improved my software architecture skills. The Singleton pattern is often the first design pattern developers encounter.

Did you still remember the memory consumption comparison between asynchronous programming across popular languages in 2023? Now at the end of 2024, I wonder how things changed in the span of one year, with the latest version of languages. Let's do the benchmark again and see the results!BenchmarkThe program to benchmark is the same with the one in the last year:Let's launch N concurrent tasks, where each task waits for 10 seconds and then the program exists after all tasks finish.

When creating classes or methods, we often deal with data of some kind. While the data types may vary, the logic remains largely the same. Generalizing such logic makes it much more versatile. This is where Generics come in—they allow us to specify data types dynamically, adding a powerful layer of flexibility. In this article, I’ll share my personal experience with implementing Java Generics for the first time, including points I struggled with and lessons I learned along the way.

The Composite Design Pattern is one of the structural patterns in software engineering that is widely used to represent part-whole hierarchies. It allows you to compose objects into tree-like structures to represent complex hierarchies, enabling clients to treat both individual objects and compositions of objects uniformly.

In Java, Upcasting and Downcasting are essential for enabling polymorphism, enhancing code flexibility, and managing object hierarchies. These typecasting techniques allow developers to handle objects efficiently, improving code clarity and scalability. This guide provides a clear overview of upcasting and downcasting, with expert insights and practical examples for real-world applications. Typecasting refers to converting one data type to another in Java.
