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.

5,708 PointsHi Jacob, You didn't specify what your problem with the challenge was. The thing with do while loops (compared to for or while loops) is that they always run, atleast once.
One of the important things is that variables you'll use as a boolean for a loop (i.e. the expression that needs to be accomplished for the loop to end) need to be instantiated and declared before and outside the loop.
My code would be:
String response = "";
do {
response = console.readLine("Do you understand do while loops");
} while (response.equals("No"));
First we instantiate and declare the String variable to = "" (if this is not declared the loop will not work). In the challenge there's already a console declared by teamTreehouse (named console) and I'm using that. While the response equals "no" the loop will continue looping. Also - note that, for Strings, you can not use the == to check for equality.
Good luck.

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