        boolean haveMoney, haveTime, amHungry, restaurantOpen, haveTransportation;
        System.out.print("Do you have money(true or false): ");
        haveMoney = in.nextBoolean();
        System.out.print("Do you have time(true or false): ");
        haveTime = in.nextBoolean();
        System.out.print("Are you hungry(true or false): ");
        amHungry = in.nextBoolean();
        System.out.print("Is the restaurant open(true or false): ");
        restaurantOpen = in.nextBoolean();
        System.out.print("Do you have transportation(true or false): ");
        haveTransportation = in.nextBoolean();
        if (haveMoney) {
            if (haveTime) {
