interface Number {
  int readNumber();
}
interface Choice implements Number {
  boolean find(int target);
}
interface ConsoleGame implements Choice {
  void success(int target);
}
public class Game implements ConsoleGame {
  @Override
  int readNumber() {
    Random random = new Random();
    System.out.printf(
      "===========================\n" +
      "        Game Start         \n" + 
      "===========================\n"
    );
    return random.nextInt();
  }
  @Override
  boolean find(int target) {
    Scanner scanner = new Scanner(System.in);
    System.out.printf("Enter number: ");
    int number = scanner.nextInt();
    if (number < target)
      System.out.printf("Lower than the target!\n");
    if (number > target) 
      System.out.printf("Upper than the target!\n");
    return number == target;
  }
  @Override
  void success(int target) {

    );
  }
  public static void main(String[] args) {
    int target = readNumber();
    while (!find(target)) {
      System.out.printf("Try again!");
