I cannot figure this out

I'm trying to do a do/while loop while continually prompting the user

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response = console.readLine("Do you understand do while loops?  ");
boolean No;
do {
  No = console.readLine("response?  ");
  if (No)
        {
                console.printf("I'm sorry.  Please review the content again. \n\n");
          }
} while(No);

First off, when creating a variable, it should never start with a capital letter. They should be camelCased. Please take a look at Java Naming Conventions.

The first task asks you to prompt the user whether or not they understand do-while loops. Then, store the response in a variable named "response."

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

The next task asks you to create a do-while loop that will continue to prompt the user

do {
    response = console.readLine("Do you understand do while loops? ");
} while (response.equalsIgnoreCase("no"));

The last task asks you to print a formatted string, "Because you said <response>, you passed the test!

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

This is what your finished code should look like:

// I have initialized a java.io.Console for you. It is in a variable named console.
String response = console.readLine("Do you understand do while loops? ");

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);
