How do I use parameters in Java?

In Java, parameters are used to pass data into methods. You define them in the method signature.

Can you give me an example of a method with parameters?

Sure! Here's a simple example:

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

You can call this method with a name as an argument.

What happens if I don't pass the required parameters?

If you don't pass the required parameters, you'll get a compilation error. Java enforces parameter requirements.

Can I use default parameters in Java?

Java doesn't support default parameters directly, but you can achieve similar behavior using method overloading.
