Java 21 Hello World and Running Your First Program
In this episode, we begin our journey into Java 21 programming. You will learn how to write a basic Hello World program and run it directly from the terminal. This lesson provides the foundation for understanding how Java source files are compiled and executed. Every concept is explained clearly so you can follow along with confidence.
We cover how to create a Java file, understand the structure of a basic Java class, compile the code using the terminal, and run the output. This is the first step in building your Java development skills and preparing for more advanced topics later in the series.
No prior knowledge is needed. Follow along and begin learning Java 21 from the ground up.
