how do i complete this do while loop question?

String response; boolean no; do { response = console.readLine("Do you understand do while? "); no = (response.equalsIgnoreCase("No")); if (no) { console.printf("Because you said <response>, you passed the test! \n\n"); } }while (no);

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

Hi Kofi Jr.,

1) \n is used to add a new line to a string, which we won't need in this case.

2) What the objective actually wants us to do is include the user's response (which we store in the response variable) in our print out to the screen. To do that, we'll use a placeholder called a string formatter, which we use by typing %s at the place in the string in which we want our variable's contents to be displayed. So that the Java compiler knows which variable we're talking about, we'll add a comma after the string and type the name of the variable we want to use. This way, the compiler knows what string variable to replace %s with.

In short, you'll want to change this line:

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

to

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

Hope this helps!
