This lab includes working with threads and simulation of working two elevators system.
To start elevators system you should input parameter of simulation (floors count, requests count and requests period).
System.out.print("Input floors count: ");
var floorsCount = scanner.nextInt();
System.out.print("Input requests count: ");
var requestsCount = scanner.nextInt();
System.out.print("Input requests interval (ms): ");
var requestsInterval = scanner.nextInt();Initializing elevators manager and start requests and elevators threads.
ElevatorsManager manager = new ElevatorsManager(floorsCount);
Thread requests = new Thread(new RequestThread(manager, requestsCount, requestsInterval));
Thread elevators = new Thread(new ElevatorsThread(manager));
requests.start();
elevators.start();Working logs will be output in the console.
Working example:
Default elevator time per floor is 1000ms = 1s
> Input floors count: 5
> Input requests count: 4
> Input requests interval (ms): 1000
💤 Elevator 1 waiting on floor 0
💤 Elevator 2 waiting on floor 0
📩 New request on 0 floor, direction up
📤 Elevator 1 take request on floor 0, direction up
✅ Passenger enter elevator 1 on floor 0
🔼 Elevator 1 going ↑. Current floor = 1
💤 Elevator 2 waiting on floor 0
📩 New request on 2 floor, direction up
📤 Elevator 1 take request on floor 2, direction up
🔼 Elevator 1 going ↑. Current floor = 2
💤 Elevator 2 waiting on floor 0
📩 New request on 1 floor, direction up
📤 Elevator 2 take request on floor 1, direction up
✅ Passenger enter elevator 1 on floor 2
🔼 Elevator 1 going ↑. Current floor = 3
🔼 Elevator 2 going ↑. Current floor = 1
📩 New request on 4 floor, direction up
📤 Elevator 1 take request on floor 4, direction up
❌ 1 Passenger(s) left elevator 1 on floor 3
✅ Passenger enter elevator 2 on floor 1
🔼 Elevator 1 going ↑. Current floor = 4
🔼 Elevator 2 going ↑. Current floor = 2
❌ 1 Passenger(s) left elevator 1 on floor 4
✅ Passenger enter elevator 1 on floor 4
❌ 1 Passenger(s) left elevator 2 on floor 2
🔼 Elevator 1 going ↑. Current floor = 5
💤 Elevator 2 waiting on floor 2
❌ 1 Passenger(s) left elevator 1 on floor 5
💤 Elevator 1 waiting on floor 5
💤 Elevator 2 waiting on floor 2
