Courses Plus Student 6,658 Pointscontinually prompt user in do while loop, declare response outside loop. im really stuck on this
Now continually prompt the user in a do while loop. The loop should continue running as long as the response is No. Don't forget to declare response outside of the do while loop. this has me stuck!
// I have initialized a java.io.Console for you. It is in a variable named console.
String noun;
boolean isInvalidWord;
do {
String response = console.readLine("Do you understand do while loops? ");
noun = console.readLine("enter a noun: ");
isInvalidWord = ("no"));
} while(isInvalidWord);
if(isInvalidWord);
console.printf("Try again. \n\n");

There's no need for the if statement. Please refer to the following:
//Declare a String variable named response, then initialize it using double quotes
String response ="";
// The do while loop keeps asking the same question until "yes" is entered
//So we want to keep repeating when "no" is typed
// Exit the loop when "yes" is entered
do{
response = console.readLine("Do you understand do while loops?"); // "yes" or "no" is stored in the response variable
// when someone types "no" the loop repeats
// when someone types "yes" the loop is exited
}while(response.equalsIgnoreCase("no"));
//After the loop exits, the following line prints to the console
console.printf("Because you said %s, you passed the test!",response); //task 3
If you have any other questions feel free to ask!

Courses Plus Student 1,033 PointsWas this information in the lesson? The lessons used console.readLine("XYZ"); and yet you introduce ="";
Trying to go lesson by lesson but people answer questions I'm stuck on with stuff we haven't seen yet?
