Java Java Basics Perfecting the Prototype Looping until the value passes

I am stuck

I know that I need to do an 'if' maybe but it doesnt tell me what to have the 'boolean' listed at...am i on the wrong track with this one?

// 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?");
} while();

In a do while loop, you keep DOing something WHILE a condition is true. You need to put a java expression in the last pair of parenthesis that returns a boolean. for example, switch in "while(response.length() > 10 )" and the program keeps running as long as you keep entering responses with more than 10 characters.
