基于两个参数的AnyLogic优先级队列的Java代码

import java.util.Comparator;
import java.util.PriorityQueue;

public class PriorityQueueExample {
    public static void main(String[] args) {
        // 创建一个优先级队列，使用自定义的比较器来确定元素的优先级
        PriorityQueue<Item> priorityQueue = new PriorityQueue<>(new ItemComparator());

        // 添加元素到队列中
        priorityQueue.add(new Item("Item 1", 3, 100));
        priorityQueue.add(new Item("Item 2", 1, 200));
        priorityQueue.add(new Item("Item 3", 2, 150));

        // 从队列中取出元素并打印
        while (!priorityQueue.isEmpty()) {
            Item item = priorityQueue.poll();
            System.out.println(item);
        }
    }
}

// 自定义的比较器，用于确定元素的优先级
class ItemComparator implements Comparator<Item> {
    @Override
    public int compare(Item item1, Item item2) {
        // 根据两个参数进行比较，优先级高的排在前面
        if (item1.getPriority() < item2.getPriority()) {
            return -1;
        } else if (item1.getPriority() > item2.getPriority()) {
            return 1;
        } else {
            // 如果优先级相同，则根据第二个参数进行比较
            if (item1.getParameter2() < item2.getParameter2()) {
                return -1;
            } else if (item1.getParameter2() > item2.getParameter2()) {
                return 1;
            } else {
                return 0;
            }
        }
    }
}

// 优先级队列中的元素类
class Item {
    private String name;
    private int priority;
    private int parameter2;

    public Item(String name, int priority, int parameter2) {
        this.name = name;
        this.priority = priority;
        this.parameter2 = parameter2;
    }

    public String getName() {
        return name;
    }

    public int getPriority() {
        return priority;
    }

    public int getParameter2() {
        return parameter2;
    }

    @Override
    public String toString() {
        return "Item{" +
                "name='" + name + '\'' +
                ", priority=" + priority +
                ", parameter2=" + parameter2 +
                '}';
    }
}
