Java Java Basics Perfecting the Prototype Looping until the value passes

Java quiz question!

The question is "Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop."

And the code that i have written is -

{ String response; response= console.readLine("Do you understand do while lopp? ");

do{ if(response.equalsIgnoreCase("Yes")) { console.readLine("Do you understand do while loop now? "); }}while(response.equalsIgnoreCase("No")); }

Please help me to solve this! Thanks! ;)

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response;
response= console.readLine("Do you understand do while lopp?  ");

do{
 if(response.equalsIgnoreCase("Yes"))
    {
   console.readLine("Do you understand do while loop now?  ");
}}while(response.equalsIgnoreCase("No"));

Hi Aryan,

The response of the question is in your case read once. You should read it each time the do while loop repeats. Right now if you answer "No" the do while will never quit because you are not asking anymore the question so the response will stick always as "No".

To fix that, move the

response= console.readLine("Do you understand do while lopp? ");

at the beginning inside the do while loop. In this case each time the do block runs it will ask you again and hence you could type another response.
