How do I use varargs in Java?

Varargs in Java allows you to pass a variable number of arguments to a method. You can define a method with varargs by using an ellipsis (...) in the parameter list.

Can you give me an example of a method using varargs?

Sure! Here's an example:

public void printNumbers(int... numbers) {
    for (int number : numbers) {
        System.out.println(number);
    }
}

You can call this method with any number of integer arguments.

Are there any limitations to using varargs?

Yes, you can only have one varargs parameter in a method, and it must be the last parameter. Also, you cannot use varargs with primitive types directly.

What happens if I pass no arguments to a varargs method?

If you pass no arguments, the varargs parameter will be treated as an empty array. The method will still execute without errors.
