Array of references to child objects failed to initialize

java, oop

Solution

Your design is way off the mark. A class should not hold an array of child objects and in fact should have no knowledge about or dependence on its child classes. This is both a recursive and a logical nightmare.

I suggest you remove the array from within the Room class to somewhere more appropriate, such as the Hotel class or House class.

Problem

I need to create array of references to child objects. In this case Room has to have array of references to objects: `DarkRoom` and `LightRoom`. Having error in line where initialization of array of type `Room`. What's missing? ``` public abstract class Room { public Room[][] space = new Room[4][4]; // <<Syntax error on token ";", space[0][0] = new DarkRoom(); space[0][1] = new LightRoom(); space[1][0] = new DarkRoom(); space[1][1] = new LightRoom(); } public class LightRoom extends Room { ... } public class DarkRoom extends Room { ... } ```
