// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
do {
response = console.readLine("Do you understand do while loops?");
console.printf("Because you said<response>, you passed the test!");

you can place a %s
placeholder within the string which will be replaced with a string you pass in as the second argument to the printf
method. Like this:
console.printf("Because you said %s, you passed the test!", response);
The challenge wants the message to be printed out after the loop runs though, not within the loop. So you need to place the printf
statement below the loop. Like this:
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!", response);
