What are some examples of parameters in Java?

In Java, parameters are variables used to pass data into methods. For example, in a method definition like public void greet(String name), name is a parameter.

Can you give me more examples of different types of parameters?

Sure! You can have primitive type parameters like int, double, or reference type parameters like String or custom objects. For instance, public void calculateArea(int width, int height) uses two int parameters.

What about default parameters? Does Java support them?

Java doesn't support default parameters directly, but you can achieve similar functionality using method overloading. For example, you can create multiple methods with different parameter lists.

How do I handle variable-length arguments in Java?

You can use varargs in Java by using an ellipsis. For example, public void printNumbers(int... numbers) allows you to pass any number of int arguments.
