Q. Design and code an Elevator. You can use any JDK, preferably JDK 8 and use collection framework, OOP principles to design a single thread elevator programme. This will test your knowledge of CORE Java. Remember to use all the standard and good programming habits while programming.
-
The Elevator class maintains the current floor, direction of movement, a map of requested paths (people waiting on each floor and their destinations), and an array to track the floors the elevator will visit.
-
The start() method repeatedly calls the processFloor() method until the elevator becomes idle.
-
The processFloor() method unloads passengers, boards passengers, updates the current floor destinations, and calls moveElevator() to determine the next direction and move the elevator.
-
The moveElevator() method determines the direction based on the current floor and updates the currentDirection variable accordingly.
-
The elevator moves up or down based on the current direction and waits between each floor.
-
The callElevator() method adds user requests to the requestedPathsMap.
-
The main method creates an Elevator object, allows users to manually call the elevator, and starts the elevator.
