57,712 PointsHi Mason,
First, you've declared response
as being a String
and get user input to a question using console.readLine()
. That's the first stage of the challenge and it looks like this:
String response = console.readLine("Do you understand while loops?: ");
You've got beyond that bit and on to stage 2. Here, you need to create a do/while
loop. The loop will always execute once and will continue to loop while
the response
equals "No". You need to amend the above response
declaration to just create a variable but assign nothing to it. Then you create a do/while
loop. That looks like:
String response;
do {
// keep doing this
response = console.readLine("Do you understand while loops?: ");
} while(condition);
The condition
is a test of what the user has input. If they have entered "No", loop. Else don't ... So we need to test if response
is "No". To compare strings, use the .equals()
method. We can build this into the code:
String response;
do {
response = console.readLine("Do you understand while loops?: ");
} while(response.equals("No"));
That's stage 2 complete! Go figure out stage 3 and let me know how you get on.
I hope that helps,
Steve.
