I have no idea what the question is asking me. It is so vague. Please be more specific.

The final question of this module asks to use a console.printf. nothing specific. what do they mean?

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

Your code is needlessly complex, i think. Maybe try:

String response = null;
do {
response = console.readLine("Do you understand do while loops  ");
} while (response.equals("No"));
console.printf("Because you said %s, you passed the test!", response);

When your response is valid, it will jump outside the do block. Hence you can just put the console print outside. Additionally, it wants you to use a placeholder with the printf.
