Task 3/3

I don't know what i am doing wrong, i am trying to print after the loop finish , and when it finish the variable response would hold the "Yes" and so i concatenate the response string with the default text. Any help would be appreciated.

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?");

}while (response.equals("No"));
 console.printf("Because you said " + response + ", you passed the test!");

Denis, your code is looking good but it has one little problem because of it you can't pass the task 3.

There are two points I need to highlight:

  1. Always "initialize" a variable with a value before using it. Initializing means inserting it with a valid value. for example, String response = ""; instead of String response;

  2. Console.printf works a bit different and what you wrote will work perfect for "System.out.print()", but for a console.printf you need to specify a format for the string to be printed on console. e.g You have a variable 

String text = "Hello";

Now in order to print it using console.printf , you will use "%s"

console.printf("%s World",text);

During runtime , it will put the value of text variable in the place of %s.

So your solution for this task is following:

// 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?");
} while (response.equals("No"));

console.printf("Because you said %s,you passsed the test!",response);

Hi Denis...

since you are using console.printf you might want to consider using format specifier placeholder "%s" for String instead of concatenation of strings. This is how you should write your last code:

console.printf("Because you said %s you passed the test!", response);

I hope this can help you a little
