About Do while loop in java

I am the opposite of clever. and i am having trouble understand "dowhileloop". Can somebody explain to me in the easiest plain way? What does it do?????? Please don't copy paste the explanation from the java documentation, i tried, couldn't understand. thankyou

Example.java
// 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.equalsIgnoreCase("no"));
console.printf("Because you said %s, you passed the test", response);

A Do...While loop will automatically enter the loop before checking if a condition is true or false. A While loop will not enter the loop until it has determined that a condition is true or false. So, you can always count on a Do...While loop to run the code inside the do {.....} block at least one time. It will then check the while(...) portion to see if the condition is true. If it is, it will repeat the code inside the do{...} block. With a While loop, the code inside the loop may never run if the condition is not true.
