boolean error java

Hello Yasine,

Remember DRY principle about repeating yourself, well Don't Repeat Yourself.

Once you have declared response as String outside the do-while loop you only need to initialize response inside the do-while loop but without using the keyword String.

boolean isInvalidWord should also be declared outside the do-while loop but initialized inside the do-while loop so that the do-while loop access to this boolean.

With do-while loop the code will run at least once and test if the condition has been met. If condition has not been met (i.e. FALSE) the code keeps looping until the condition becomes TRUE.

Please refer to the below code sample and let us know.

Part One

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

Part Two

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

}
while(response.equalsIgnoreCase("No"));

Part Three_

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

}
while(response.equalsIgnoreCase("No"));

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