I've tried a couple of things and nothing is working but it doesnt tell me whats wrong. Help?

Ive done an if statement, another string, nothing seems to work but it doesnt tell whats the problem as well.

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
console.readLine("Do you understand do while loops? ");
String response = "No"; 
boolean result;
  do{
    response = console.readLine("No");
    result = ("No").equalsIgnoreCase(response);

  } while(result);
    console.printf("I'm Having a Hard Time");

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);

All you need is one String variable (response), you can delete the boolean variable. Within the do while loop you need to ask the user "Do you understand do while loops?" and store the users answer in the 'response' variable. Next, you need to test the user's response by checking the contents of the 'response' variable - this is done within the while parameters-while(response.equalsIgnoreCase("no")).
