Something wrong but i cannot see what

can anyone help me out come with error telling me my syntax is wrong

Example.java 
// 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?"    );
isInvalidWord = (response.equalsIgnoreCase("No"));
if (isInvalidWord) {
          console.printf("that language is not allowed.  Try again. \n\n");

I commented out all of the wrong code, but there were a number of issues:

  • You never declared a variable type for isInvalidWord.
  • They never asked you to print "that language is not allowed. Try again." I think you may have copied this from the previous videos
  • You forgot the while part of the do while.
// 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?");
/* <---------------------------------This block of code is not needed
    isInvalidWord = (response.equalsIgnoreCase("No"));
    if (isInvalidWord) {
        console.printf("that language is not allowed.  Try again. \n\n");
    }
*/ 
} while(response.equalsIgnoreCase("No"));

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

I'm having a problem with my browser right now that's not allowing me to try the code challenge, but just by looking at your code, it looks like you're missing the WHILE clause of the DO-WHILE loop. Also, the isInvalidWord variable doesn't have a type declared. Looks like it should be Boolean. You also don't need the parenthesis around response.equalsIgnoreCase("No").

I'll check in again to see if I can attempt the code challenge. Hope this points you in the right direction for now. Let me know if you have any questions.
