    Running Java programs from the Command Prompt (CMD) is a straightforward process that involves a few essential steps. Before you begin, ensure that the Java Development Kit (JDK) is installed on your system and the path is properly set.

    Writing and Saving the Java Program

    First, create a Java program using a text editor like Notepad. For example, you can write a simple "Hello, World!" program:

    public class HelloWorld {
    public static void main(String[] args) {
    System.out.println("Hello, World!");
    }
    }
    Copied!

    Save the file with the .java extension, ensuring the filename matches the class name. For instance, save the above program as HelloWorld.java.

    Compiling the Java Program

    Open the Command Prompt by pressing Windows Key + R, typing cmd, and pressing Enter. Navigate to the directory where you saved your Java program using the cd command:

    cd path\to\your\directory
    Copied!

    Compile the Java program using the javac command:

    javac HelloWorld.java
    Copied!
