%s I forget how the format of using these variable replacement operators do

Can somebody tell me how this works

IO.java
// I have imported java.io.Console for you.  It is a variable called console.
String firstName = console.readLine("this is your first name");
String lastName = console.readLine("this is ur bchhh");
console.printf("First name: " + firstName);

console.printf("First name: %s", firstName);

I believe this is the proper syntax for using %s. The printf command will see you added %s to the string, then search through the added arguments in order and replace %s with the argument.
