What are the different parameter types in Java?

What are the different parameter types in Java?

In Java, parameters can be classified into two main types: primitive types and reference types. Primitive types include int, char, double, etc., while reference types include objects and arrays.

Can you give me examples of both types?

Sure! For primitive types, an example is int number = 5;. For reference types, you might have String name = "John"; or int[] numbers = {1, 2, 3};.

What about variable-length arguments?

Variable-length arguments, or varargs, allow you to pass a variable number of arguments to a method. You can define a method like this: public void myMethod(int... numbers) {}.

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, it can only be of one type.
