Java Basics

Prompt the user with the question "Do you understand do while loops?" Store the result in a new String variable named response.

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.

String response;
do {
  String response = cnsole.readLine("Enter a respond:  ");{
   if(equelsIgn
       console.printf("That is true");
       }
       }while(equelsIgnoreCare);

Check your spelling on console and equalsIgnoreCase. Completely junk the if statement, that will be handled by the do-while. also make sure when you use equalsIgnoreCase you are calling the method on an Object and passing it a parameter like this:

response.equalsIgnoreCase("no");

Hope this helps

Hi Jules,

let me modificate your code a little bit.

Do while loops look like this:

do {
//your code
}while(//condition);

And here your modified code:

String response;
// declare a variable outside the scope of the loop, so you can use it everywhere
do {
  response = console.readLine("Enter a respond:  ");
// typo inside console ( not cnsole)
// this will be executed at least once and if the condition inside the while parenthesis is true
// you don´t need to write String again, you declared a String variable "response" above
// you don´t need an if statement here
       }while(response.equalsIgnoreCare("no"));
// while response is "no", repeat the part inside the do block
// you had a typo inside equalsIgnoreCase (not equels) :)

Let me know if you need more help
