Anylogic - 停车延迟块

Question

有没有人知道如何获得一个函数的值来指示街区是否有任何空停车位。 我正在使用队列，我尝试了函数nFree() 和spaceIndex()，但我发现这两个函数没有为类型定义

希望我理解你的问题，下面是可能返回所有停车位的代码。

public class Parking {

    static int parkingSize = 10;

    static Object[] object = new Object[parkingSize];

    public static void main(String[] args) {

        add("java", 10);

        System.out.println(checkEmptyParkingSpot());

        emptyParkingSpot(10);

        System.out.println(checkEmptyParkingSpot());

    }

    // add the object in specicif location
    public static void add(String info, int position) {

        // if the position does not exist an erro will be thow
        if (position > object.length ) {
            throw new RuntimeException("The possition indicated does not exist in the park");
        }

        if (object[position - 1] != null) {
            throw new RuntimeException("The possition is ocupied");
        }

        object[position - 1] = info;

    }

    // to remove an object from the park and free the space
    public static void emptyParkingSpot(int position) {

        if (position > object.length ) {
            throw new RuntimeException("The possition indicated does not exist in the park");
        }

        if (object[position - 1] == null) {
            throw new RuntimeException("The possition isalready empty");
        }
        object[position - 1] = null;
    }

    // lists the empty spot 
    public static String checkEmptyParkingSpot() {

        String emptySpace = "".trim();

        for (int i = 0; i < object.length; i++) {

            // list the empty space
            if (object[i] == null) {
                emptySpace = emptySpace + (i + 1) + "\n";
            }

        }

        // if there is no space the message will be park full
        if (emptySpace.isEmpty()) {
            emptySpace = "Park is Full";
        }

        return emptySpace;
    }

}
