Formatting string in Java using return string.format(...)

Question

Say I want to return something like this: "Title bookTitle, Author bookAuthor: $cost"

The ones in bold are variables. I can't figure out how to return this using string.format("%s .., blah blah")

String title = "bookTitle";
String author = "bookAuthor";
double cost = 100;
String text = String.format("Title %s, Author %s: $%.2f", title, author, cost);
System.out.println(text); // prints "Title bookTitle, Author bookAuthor: $100.00"
// or System.out.pritnf("Title %s, Author %s: $%.2f", title, author, cost);
