2. What is Java? – An Overview of the Java
Java is an object oriented programming language. Java has significant usage in building many applications, most significantly, Automation apps. Developers use Java with the principle of “write once and run anywhere” (WORA). Furthermore, it is portable. Therefore, a program based mainly in Java will run equally on varied hardware and operational systems.
The Java was developed by James goose and also the “Green Team” at Sun Micro systems in 1991. It’s an associated object-oriented, class-based, general artificial language.
Stability, efficiency, and cross-platform capabilities are included in Java’s main characteristics. As a result, Java is one of the well-liked and severely used object oriented programming languages around the world.
When combined with runtime surroundings, Java becomes a platform/framework. i.e., JVM ( the Java Virtual Machine). Thus, there are primarily four platforms of Java:
- Java SE – Java Platform, Normal Edition
- Java EE – Java Platform, Enterprise Edition
- Java Maine – Java Platform, Small Edition
- Java FX
Pros and Cons of java
Advantages of Java

This way, it increases Nodejs’ efficiency and scalability.
How scalable is Java?
Java is vastly scalable, which makes it more outstanding in performance for enterprise applications. The EJB (Enterprise Java Beans), known as development architecture, is attended by an application server that simplifies multiple requests. This way, it offers fair scalability. You must implement some best practices to improve, like vertical scalability to add more computational resources such as CPUs and RAM. Here are some additional techniques you’ll be able to follow:
- Horizontal Scaling
- Vertical Scaling
- Introduce a Single point of failure
- Use a one-size-fits-all architecture
6. Application architecture – Node vs Java
When selecting a framework, it’s vital to choose flexibility and avoid strict implementation of architecture and guidelines. So let’s compare Node.js and Java with one other and check whether or not they are flexible in architecture.
What kinds of architecture will Node.js support?
Under the cover, Single-threaded Event Loop architecture enables it to handle multiple concurrent requests with better performance. Nodejs also allows you to use MVC/ MVP architecture patterns, eases separating and boarding issues in the application code-base. Plus, it creates multiple views for the same data and supports asynchronous communication between many components.
Here’s how the async architecture of Nodejs advantages you:
- Processes multiple synchronous requests at the same time and offers high performance.
- Guarantees faster and flexible development of modules.
- Decreases time-to-market of applications.
What Types of architecture will Java support?
Developers like to use the model-view-controller (MVC) pattern to develop applications in Java programming language where the Model is objects in Java, and the design pattern seems like the inner architecture of the language. You will easily maintain the code and have trouble-free testing of applications. Development teams will categorize individual roles and work on the various functionalities in large applications.
So, changes in one module don’t affect the whole application. Instead, it will increase development teams’ productivity and result in faster time to market apps.
