what am I missing?

I cant figure out whats wrong

Example.java 
// I have initialized a java.io.Console for you. It is in a variable named console.
String response ;
do {
  response =console.readLine("Do you understand do while loops");
  if(response.equals ("No"))
   console.printf("Do you understand do while loops");
}while (response.equals ("No"));
 console.printf("Because you said No, you passed the test!");

Hi Milly,

Your loop is mainly correct; it does the job. But you can delete the if statement in there as wellas the second question prompt; the printf isn't needed as your readLine does that for you.

Outside of the loop, the challenge wants an output that uses printf to insert the contents of response into the string. The output should be, "Because you said Yes, you passed the test!", or something like that.

So, insert a %s placeholder within the output string and use the format, printf("some text %s some text", response); to insert the right value in there.

I hope that helps,

Steve.

String response ;
do {
  response =console.readLine("Do you understand do while loops");
  if(response.equals ("No")) // delete this line
   console.printf("Do you understand do while loops"); // delete this line
}while (response.equals ("No"));
console.printf( "Because you said %s, you passed the test!",response) // add a semi colon

Hi Milly,

I added some somments in your code. You've pretty much got that task nailed! Good work. :+1:

You should end up with this:

String response;

do{
  response = console.readLine("Do you understand while loops?: ");
} while(response.equals("No"));
console.printf("Because you said %s, you passed the test!", response);

Steve.
