Empty while loop

[diamonddragon]

Is ok to use an empty while loop?

Say:

        do {                 
            char[][] word = generateWord(words);
            while (guess(word)) {                                               
            }
            System.out.println("You missed " + missedCount + " time");
        }
        while (playAgain());
    }

Yes. In general {} is a perfectly well defined block.

It is another question whether you want to do this. In your example you won't get past the empty block until guess(word) returns false. Is this what you want to happen?

Yes, and guess(word) actually returns false in case word is guessed.
In all other cases, which means, letter is already in the word, letter is not in the word, and word is not guessed, guess(word) returnes true.
