Java Java Basics Perfecting the Prototype Looping until the value passes

do I have to declare a boolean in order to do this is exercise?

The question does say I have to but do I indeed need to declare a boolean for this exercise?

Example.java
// I have initialized a java.io.Console for you. It is in a variable named console.
console.readLine("Do you understand do while loops");
String response = ("Not Really? ");
    do {
      response = console.readLine("No");
    }
} while response;
  console.printf("I'm having a hard time");

Hi C.J. Doyle,

You'll need to use a boolean expression to the while stop condition. You can declare a boolean variable or doit directly on the conditional statement. For example:

Case a.-

console.writeLine("Do you understand do while loops"); String response = ("Not Really? "); boolean result = true; do { response = console.readLine("No"); result = ("No").equalsIgnoreCase(response); } while (result); console.printf("I'm having a hard time");

Case b.-

console.writeLine("Do you understand do while loops"); String response = ("Not Really? "); boolean result = true; do { response = console.readLine("No"); } while (("No").equalsIgnoreCase(response)); console.printf("I'm having a hard time");

I hope it is helpful. Remember vote for the answer

Thank you!

I will just give you a start up, just give it a try

String response = ""// you do it outside the loop, not to declare a variable all the time

do{
//code comes here, dont forget the semicolon
}while()//boolean condition, comes inside the brackets, dont forget the semicolon
