A good answer might be:

No. All the user knows is that something is wrong.

Here is a skeleton of the program:

class ComboLock
{
  public static void main ( String[] args )
  {
    boolean correct = true;

    //First Number
       ... possibly change correct

    //Second Number
       ... possibly change correct

    //Third Number
       ... possibly change correct

    //Result
    if ( correct )
      System.out.println("Lock opens");
    else
      System.out.println("Lock does not open");
  }
}

Check back to the flowhart and study how the boolean variable correct works. In the program, the if statement is correclty written. The boolean variable correct will be either true or false. All that the if statement needs is that. You don't need to do this:

    if ( correct == true )

QUESTION 4:

Will correct ever be set back to true after it has been set to false?
