Do while loop help

Im not exactly sure if i am doing this activity correctly.

// 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?");
        String response = console.readLine("What is your question?");

Hey alessandro,

During the first prompt, you of course need to declare a String variable called response and assign it the value returned by the readLine method. Be careful, as you are currently using an incorrect assignment operator. You should use an equal (=) symbol instead of a dash (-).

String response = console.readLine("Do you understand do while loops?");

Prompt two is a little more tricky. You'll want to declare your String variable outside of the loop. But you'll want to assign it a value inside of your do while loop instead of outside. The reason being so that the user will be continuously prompted with the question until the value is equal to 'No'.

An if statement is not needed in our case and neither is a nested while loop. The while goes outside of the loop, near the end. With that said, the end result looks like this:

String response; // Declare your value
do {
  response = console.readLine("Do you understand do while loops?"); // Prompt the user
} while ( response == "No" ); // Run the loop while response is equal to 'No'
