I'm creating a commercial airline flight program and I'm still learning how to get around with Java. So, I was wondering if there was any way to check if an array has enough consecutive positions to place values together in those positions in the array? For example, I have an array of strings called seats, each position in this array corresponds to an available seat on the flight. Initially these seats are all empty.
String[] seats = new String[8];
In the long-run, this program is going to be inserting values into this array and I want my program to be able to check if there are any empty seats(positions) in the flight(array) to assign a passenger to a seat. I sketched this to check.
for(int i=0; i< seats.length-1;i++) {
if(seats[i] != null) {
do something;
} else {
system.out.println("No seats available");
(how do I not assign seats or accept more values to my array?)
}
}
but advised on using an objective approach, I got to this
private static int MAX_SEATS = 8;
private String[] seats = new String[MAX_SEATS];
public boolean addPassenger(String passengerName) {
for (int i = 0; i < seats.length; i++) {
if (seats[i] == null) {
seats[i] = passengerName;
return true;
}
}
return false;
}
If the program finds an empty seat after checking, It should then check again if there are empty consecutive seats. (For example, if we wanted to make 3 passengers seat together, the program should check if there are empty 3 seats and then seat them there). If the program finds 3 consecutive positions in the array, it should randomly assign the passengers to whichever 3 position. otherwise it should randomly try another seat, repeating until successful. Right now, my array of seat can take up to 8 values, so the possible 3 positions could be (1,2,3 or 2,3,4 or 3,4,5 or 4,5,6 or 5,6,7)
. If the program does not find a consecutive position to seat these 3 people, it should randomly place them in different positions.(pick random seat numbers till it can find an empty seat) This code is just adding passengers to the seats array .
//accepting more values to the seats array
public boolean addPassengers(String... passengerNames) {
boolean everyoneAdded = true;
for (String passengerName : passengerNames) {
everyoneAdded = everyoneAdded && addPassenger(passengerName);
}
return everyoneAdded;
}
How is it possible to check for consecutive positions in an array in order to add groups of passengers randomly? Any correction/contribution would be helpful.
