Compiler Error

Hello,

I'm getting the following error when I try and run my code:

JavaTester.java:123: error: incompatible types: boolean cannot be converted to String isInvalidWord = console.readLine(response.equalsIgnoreCase("No")); ^ Note: Some messages have been simplified; recompile with -Xdiags:verbose to get full output

1 error

Does anyone have any suggestions for why I'm getting the error? I'm at a loss.

Thanks!

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
boolean isInvalidWord;
do {
 response = console.readLine("Do you understand do while loops?  ");
 isInvalidWord = console.readLine(response.equalsIgnoreCase("No"));
 if (isInvalidWord) {
    console.printf("Why not?");
 }
} while(response.equalsIgnoreCase("No"));

Jason is right. Here's the code that passed for comparing:

String response;
boolean responseIsNo;
do{
  response = console.readLine ("Do you understand do while loops?  ");
  responseIsNo = response.equalsIgnoreCase("No");
  if(responseIsNo){
  console.printf("Try again!");
    }
  }while (responseIsNo);

Since you've already got input from user for the string response, on the next line you just need to check whether it's equal to set the value of isInvalidWord rather than read another input. So i think it should read:

isInvalidWord = (response.equalsIgnoreCase("no"));
