Can someone help me understand what "use console.printf and to write out the formatted string" means? Thanks!

Last Java Basic Challenge Trouble

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean isInvalidResponse;
do {
response = console.readLine("Do you understand do while loops?  ");
isInvalidResponse = (response.equalsIgnoreCase("no"));
if (isInvalidResponse) {
console.printf("Because you said response, you passed the test!  \n\n");
  }
} while(isInvalidResponse);

String response = "";

do {

  response = console.readLine("Do you understand do while loops?  ");

} while(response.equalsIgnoreCase("No");

console.printf("Because you said %s, you passed the test! \n", response);

The console is a way to print information to the screen. printf is a way to format the information passed to the screen. If you notice, I have a %s in my printf statement- that is a place holder for my string variable. If I had a %d there it would be placeholder for a int (integer).
