Hello Java Program

The simple “Hello, Java!” program in Java:

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

This Java program does the following:

1. Defines a class named HelloWorld.
2. Inside the class, there is a main method, which is the entry point for the program.
3. Inside the main method, the System.out.println() statement is used to print the message “Hello, Java!” to the console.

To run this program, make sure you have Java installed on your system and follow these steps:

1. Create a file with the .java extension, e.g., HelloWorld.java.
2. Copy and paste the above Java code into the file.
3. Open your command prompt or terminal.
4. Navigate to the directory where the Java file is located.
5. Compile the Java code by running javac HelloWorld.java.
6. Run the compiled program with java HelloWorld. You should see the “Hello, Java!” message printed to the console.

This program is a simple starting point for writing Java applications. It demonstrates the basic structure of a Java program, including the class definition, the main method, and how to output text to the console.
