Java Void

Java void

Created By: chatGPT

Java is a popular programming language that follows the principles of object-oriented programming (OOP). A void return type indicates that a method does not return any value. It is often used for methods that perform an action but are not supposed to return a result. Here’s a simple example of a method with a void return type:

public void printHello() {
    System.out.println("Hello, World!");
}

In the example above, the printHello method does not return any value. Instead, it simply prints a message to the console. Void methods can still change the state of an object or affect other data. Below is an example of a class that demonstrates a method with a void return type.

class Greeter {
    public void greet(String name) {
        System.out.println("Hello, " + name + "!");
    }
}

You can call the greet method by creating an instance of the Greeter class. Here's how you would do it:

public class Main {
    public static void main(String[] args) {
        Greeter greeter = new Greeter();
        greeter.greet("Alice"); // Prints: Hello, Alice!
    }
}

In this code, an instance of the Greeter class is created, and the greet method is called with the argument "Alice". Even though the method is declared as void, it effectively provides output to the user through the console. Keep in mind that while the method does not return a value, it can still perform operations that affect the program's state or output.
