Java Java Basics Perfecting the Prototype Looping until the value passes

help me please!

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.

Example.java
// I have initialized a java.io.Console for you. It is in a variable named console.
String respones;
do {
whileLoop = console.readLine("Do you understand while loops?  ");
respones = whileLoop;
  no = (respones.equalsIgnoreCase("No"));
} while(no);

Hi Petter,

You're nearly there with this.

First, you've declared the variable response before the loop - the challenge enforces the name of the variable - it might be worth checking its spelling.

Inside the loop, you are prompting for user input using readLine - that's correct. However, assign whatever the user enters into response so that response = console.readLine ... etc.

Then, the while condition, as you've put, is testing, using equals or equalsIgnoreCase, whether the response is "No". Do this within the brackets after the while keyword.

So:

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

That should get you through the challenge.

Steve.
