317 PointsWhen to use parentheses
Hello,
When do you know to put parentheses? I've notice that some has parentheses and some doesn't For example
console.printf("Hello"); For this one you use parentheses However
String names = "Alex"; You dont use parentheses on this one. Why is that??
Hopefully it made sense. :)

You will learn later in the course about methods and it should clear up then. Methods are used in classes and you can pass in a value that the method requires and it uses that when the method is run. It will make sense when you get further into the course.
