28,558 PointsSure, I've also added some comments to hopefully make the code a bit clearer for you.
String response = console.readLine("Do you understand do while loops?");
//First prompt the user and store the result to the response String.
do {
//Start a do loop, do loops run the code in them once,
//then repeats it while the condition it has been given is true.
response = console.readLine("Do you understand do while loops?");
//Sets the response equal to the prompt again.
} while (response.equals("No"));
//Here we declare the condition for the do loop to continue.
//We are checking if the response variable is equal to the string "No".
console.printf("Because you said %s, you passed the test!", response);
//Then finally we are printing out a formatted string.
//In a formatted string %s is used as placeholder for string variables.
//The second argument passed to printf is the first variable we want to pass into the placeholder.
Edit: Made some minor changes mainly to clarify some stuff about the do loop.

10,497 PointsString response = false;
do {
response = console.readLine("Do you understand do while loops?");
} while (response.equals("No"));
console.printf("Because you said %s, you passed the test!", response);
For my example, I asked for the response inside of the loop. The reason for this is in the nature of the do-while loop. Since the do {block}
will execute once before it checks the condition of while
, we can go ahead and ask for the input after the loop starts—remembering to declare the response variable above the loop;
