Answer 1

For a start, your call to keyboard.nextInt() (and its corresponding println of "Guess a number between 0-100") should be within your while loop.

Then you should consider changing your while loop to

while (true) {
    // read input from user
    if (guess < value) { // tell user their guess is too low
    } else if (guess > value) { // tell user their guess is too high
    } else { // tell user congrats, and call break to exit the while loop }
    }
}

Once you get that right, you can work on the nice-to-haves, like checking numbers guessed are within bounds, keeping track of how many guesses they've done, etc
