Double Quotes in String variable

Hi there! I think I understand what you're asking, but I'm not 100% sure. Double quotes is how we refer to a string literal. I believe the parentheses you're referring to are the ones he uses console.printf which is a method run on the console object. I promise you'll learn more about that later. But let's take a look at an example:

String greeting = "Hi there, Simon.";
console.printf(greeting);
console.printf("  How are you?")

The result of this will be two messages printed out one after another. It will look like: Hi there, Simon. How are you?. Because we send in the greeting variable directly in the first print statement, we don't need the quotes. The quotes are there in the variable declaration. That's how we define a string. The second print out needs quotes because we're not sending in a variable rather we're sending in a string literal directly.

Hope this helps!
