592 PointsDouble Quotes in String variable
Hi, I'd like to know why double quotes used in the string variable & not parentheses ?

Treehouse TeacherHi 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!
