Question

1) The first loop I need to use is a do/while. In this loop the user is prompted to type in a word. If the user types in the wrong word they get an error message:

Invalid! Try Again! 2 attempt(s) left!

Invalid! Try Again! 1 attempt(s) left!

Sorry! You have no more attempts left!

This output works as long as the wrong word is entered each time, but if the correct word is entered after 1 failed attempt it still applies the error message

2) Within my second loop (for loop) the user is asked to enter “3 * 8 = ” This portion of the loop works fine if a wrong number is entered all 3 times or if 24 is entered on any attempt.

The problem lies in the loop after 24 is entered. The output is as follows:

Thank you blah blah. We’ll call you at 5555555555 if you’re a winner. 3 * 8 = Where the 3 * 8 should not be showing. I realize I could enter a break; after this statement, but the instructions specifically say that I cannot use the break command.

The correct output should read: Thank you blah blah. We’ll call you at 5555555555 if you’re a winner.

public static void main(String[] args)
{
    Scanner input = new Scanner(System.in);

    int attempt = 2;
    int answer = 24;
    long phoneNumber = 0;
    String firstName = "";
    String lastName = "";
    String wordOfTheDay = "";

    System.out.printf("Enter the word of the day:  ");
    wordOfTheDay = input.nextLine();

    if(wordOfTheDay.equals("tired"))
    {
        for( attempt = 2; attempt >= 0; --attempt)
        {
            System.out.print(" 3 * 8 = ");
            answer = input.nextInt();
            input.nextLine();

            if( answer == 24)
            {
                System.out.printf( "Please enter your first name, last name, and phone number (no dashes or spaces)\n"                              +"in a drawing for an all-expenses-paid vacation in the Bahamas: " );

                firstName = input.next();
                lastName = input.next();
                phoneNumber = input.nextLong();

                System.out.printf(
                    "Thank you %s %s. We'll call you at %d if you're a winner.",
                    firstName,
                    lastName,
                    + phoneNumber);
            }

            else if( answer != 24)
            {
                if(attempt!=0)
                {
                    System.out.printf( "Invalid! Try Again! %d attempt(s) left!\n ", attempt);
                    continue;
                }
                else
                {
                    System.out.print( "Sorry!  You have no more attempts left!" );
                }
            }
        }
    }
    else
    {
        do
        {
            System.out.printf( "Invalid! Try Again! %d attempt(s) left!\n ", attempt);
            --attempt;
            System.out.printf("Enter the word of the day:  ");
            wordOfTheDay = input.nextLine();
        } while (attempt >= 1);

        if( attempt == 0)
        {
            System.out.print( "Sorry!  You have no more attempts left!" );
        }
    }
}

I hope I made this clear enough.

To recap, I need to fix the problem with my do/while not letting me enter the correct word after a failed attempt.

Also, I need to get rid of the 3 * 8 = showing up after the users enters the correct input.

Answer 1

Normally, you would use the break statement, but as you are not allowed setting attempt = -1 will have the same effect:

if( answer == 24)
{
    ...
    attempt = -1; // An ugly 'break'
}

EDIT:

Move the do { } while(); to before if check:

    // These two lines of code are no longer required.
    //System.out.printf("Enter the word of the day:  ");
    //wordOfTheDay = input.nextLine();

    do
    {
        System.out.printf("Enter the word of the day:  ");
        wordOfTheDay = input.nextLine();

        if(!wordOfTheDay.equals("tired"))
        {
            System.out.printf(
                "Invalid! Try Again! %d attempt(s) left!\n ", --attempt);
        }
        else
        {
            attempt = 0; // Another ugly 'break'
        }
    } while (attempt >= 1);


    if(wordOfTheDay.equals("tired"))
    {
    }
    // Remove else branch as not required.
