I am having trouble getting the do while concept. Please check this code.

Do while syntax

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response = console.readLine("Do you understand do while loops?");
boolean notAccept; 
  do{
notAccept = response.equalIgnoreCase("no");
  if (notAccept); {
      console.printf("try again");
};
    while(notAccept);

Hey Shahir,

You have a couple problems in your code.

  1. The response variable should be declared outside the loop but defined inside it.

  2. You don't need the boolean

  3. You don't need the if.

  4. The While should be response == "No"

All in all this code challenge should look like this 

// 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?");
  }
    while(response == "No");
console.printf("Because you said %s, you passed the test!", response);

Hope this helps and if this does please make this the best answer.
