# Why Java?

To start, it's important to understand why people choose Java. What makes it stand out compared to other programming languages? How does Java work and perform operations?

First, it's worth noting that many highly popular websites and games today are built with Java. Some notable examples include the **official Pentagon website**, **Netflix**, **Amazon**, **PayPal**, and many more. Java is an established, reliable programming language that is regularly updated every six months, ensuring its stability.

## How does it work? 

Java is purely an **object-oriented language**. You'll learn what that means and how to use it in the upcoming lessons. For now, just know that object-oriented programming is very **convenient and popular**. Programmers prefer Java because the code written in this language is **easy to understand and extend**.

In addition, Java is a cross-platform programming language. Let's take a look at how this cross-platform capability works:

Java is known for its **Write Once, Run Anywhere** principle, which is made possible by the **JVM** (Java Virtual Machine). We'll go into more detail about this in the <a href="https://codefinity.com/courses/v2/0bfa1111-8677-478f-bcd3-315dff1d7d40" target="_blank">next course</a>.

The JVM converts the code we write into machine bytecode, which can be understood by any system or computer. This means **you can even run Java code on a refrigerator** (as long as the refrigerator has a Java compiler installed).

These and many other factors make Java a top choice for development.

Learn the fundamentals of Java and its key features in this course. By the end, you'll be able to solve simple algorithmic tasks and gain a clear understanding of how basic console Java applications operate.

Discover the unique features of Java and understand why it's a recommended programming language to learn. Write your first Java code and explore how to print text to the console.

Learn the basics of programming, dive into primitive data types, and explore operations with them. Write code that performs mathematical tasks and evaluates conditions for seamless execution.

Explore various loops such as for, while, and do-while, which are essential in any programming language. Loops enable efficient iteration over large datasets, saving significant time. Apply them extensively in tasks like sorting, working with arrays, collections, and more.

Learn how to effectively use arrays in Java programming. We will discover how to group data into arrays and explore common methods and properties for working with them. We will also examine techniques for manipulating and optimizing arrays in real-world applications.

Learn about String, a crucial data type in Java. You will discover its many built-in methods and operations. You will explore String and StringBuilder, learning their basic methods and how to use strings effectively in Java.
