while (input <= 100) {
input = keyboard.nextInt();
}

keyboard.close();
}

}
```

Are we there yet?

```import java.util.Scanner;

public class AreWeThere {

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

System.out.print("Are we there yet? ");

System.out.print("Are we there yet? ");
}

System.out.println("Whew!");

keyboard.close();
}

}
```

Tally up

```import java.util.Scanner;

public class Tally {

public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
int input;
int sum = 0;

input = keyboard.nextInt();
while (input >= 0) {
sum += input;
input = keyboard.nextInt();
}

System.out.println(sum);

keyboard.close();
}

}
```

Guess again

```import java.util.Random;
import java.util.Scanner;

class GuessingGame {

public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
Random myRandom = new Random();
int randomNumber;
int guess;

randomNumber = myRandom.nextInt(10) + 1;

System.out.print("Guess a number from 1 to 10: ");
guess = keyboard.nextInt();

while (guess != randomNumber) {
System.out.print("Guess a number from 1 to 10: ");
guess = keyboard.nextInt();
}

keyboard.close();
}

}
```

Two in a row

```import java.util.Scanner;

public class TwoInARow {

public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);
int previous, current;

previous = keyboard.nextInt();
current = keyboard.nextInt();

while (current != previous) {
previous = current;
current = keyboard.nextInt();
}

System.out.println("Done!");

keyboard.close();
}

}
```
