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;
