java - 无法使用 instanceof 比较两个对象

Question

当尝试比较作为参数传递的两个对象时:第一个作为对象，第二个作为对象数组(同类)。出现错误 不兼容的条件操作数类型 Room 和 allRooms[]。我试图在 while 循环中迭代，直到 thisRoomType 不等于 rooms 中的某个对象。如何解决？

public abstract class Room { ...}
public class LightRoom extends Room  {...}
public class DarkRoom extends Room {...}

来电者:

release(thisRoomType, rooms)

带参数

private Room thisRoomType = this; // is defined in DarkRoom and LightRoom 
private Room[] rooms; // is defined in DarkRoom and LightRoom 

在方法中:

public synchronized void release( Room thisRoom,  Room[] allRooms) {

        try {
            int j = 0;
            while(thisRoom instanceof allRooms[j]){     
                jj++;
            }
                        int nextRoom = jj;
...
    }
}

Answer 1

试试这个:

while (j < allRooms.length && thisRoom.getClass().equals(allRooms[j].getClass()))
