How do you write a "do while loop?"

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?");
{

Hey Mo

Do/While loops are covered in the Video right before the challenge. Maybe have a quick review, and then give the challenge another go.

A do/while-loop looks like this:

do{
  //code
}while(expression)

So in words: The do/while-loop executes your code over and over again until your expression is no longer valid or as long as the expression holds (depends on how yopu define it). In pseudo-code it looks something like this:

int sum = 0;
do{
   sum = sum+1;
}while(sum < 5);

I hope it helps and I'm not too wrong
