shows cannot find symbol on "."

String response; do { response = console.readline("that question:"); }

while(response.equalsIgnoreCase("NO"));

Whats 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 u understand d loops");
} while (response.equalsIgnorecase("NO"));

Hey there Rishabh,

I see that you already got this sorted out, but your hunch is exactly right, in the example you showed us the error would crop up at equalsIgnoreCase, because the 'c' wasn't capitalized. What this error means is that it couldn't find the method that you were trying to call. It looks like you went through and did it again and sorted it out though, so good job.

What I wanted to clarify was the reason it pointed at the dot, that dot is useful, but not at all 100% correct, think of it more like a hint than an absolute answer. It pointed to the dot because the dot was the last thing that Java compiled correctly, when it got to the method after it it didn't find the method due to the letter not being capitalized, so it pointed you to where it believes the error occurred.

In any case, good job finding it out, hope the explanation clarifies a bit.

You might be failing due to using the longer method call or for NO being capitalised.

The following gets past that part:

String response;
do {
  response = console.readLine("Do you understand do while loops?");
} while (response.equals("No"));

i used (response.equalsIgnoreCase("no"));

that removes the casing of it ........
