To run this program, you need to have Java installed on your computer. Save the code in a file named `HelloWorld.java`, open a command prompt or terminal, navigate to the directory where you saved the file, and compile and run the code using the following commands: ```shell javac HelloWorld.java java HelloWorld ``` After executing the second command, you should see the output "Hello, World!" printed on the console.

Certainly! Here's an example of a simple "Hello, World!" program in Java:
```java
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
```
When you run this program, it will output "Hello, World!" to the console. Let me explain the code:
- The program starts with the declaration of a public class named `HelloWorld`. In Java, the filename must match the public class name.
- Inside the `HelloWorld` class, there is a `main` method. This method is the entry point of the program and will be executed when you run the code.
- The `main` method takes an array of strings (`args`) as a parameter, although in this simple example, we are not using it.
- Within the `main` method, there is a single line of code: `System.out.println("Hello, World!");`. This line prints the text "Hello, World!" to the console.
To run this program, you need to have Java installed on your computer. Save the code in a file named `HelloWorld.java`, open a command prompt or terminal, navigate to the directory where you saved the file, and compile and run the code using the following commands:
```shell
javac HelloWorld.java
java HelloWorld
```
After executing the second command, you should see the output "Hello, World!" printed on the console.
