I don't understand what the comment of the top of this exericse means about java.io.Console?

I don't understand what I am supposed to do with the comment that was mentioned about a variable named console. Can someone help me out?

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

String response;
boolean yesOrNo;

do{
  response = console.readLine("Do you understand do while loops?"); 
  //yesOrNo = (response.equalsIgnoreCase("no"));
  if( response.equalsIgnoreCase("yes") ) {
    System.exit(0);    
  }
} while( response.equalsIgnoreCase("No"));

The comment says that java.io.Console is defined in a variable named console. This means you can use console.readLine() instead of java.io.Console.readLine().
