创建自定义类的数组

Question

问题已解决，不再需要

Answer 1

替换

(ObjectContainer[]) new Object[initialCapacity];

通过

new ObjectContainer[initialCapacity];

因为Object 不能转换为ObjectContainer

编辑 1： 使用提供的类，以下代码会编译

public class Main {

    public static void main (String args[]) {
        ObjectContainer[] containers = new ObjectContainer[3];
    }
}

class ObjectContainer extends Object {
    String object;

    private ObjectContainer(String object) {
        this.object = object;
    }
}

编辑 2： 以下代码确实编译

public class Main {

    public static void main (String args[]) {
        ObjectContainer[] containers = new ObjectContainer[3];
    }
}

class ObjectContainer extends Object {
    String object;

    private ObjectContainer(String object) {
        this.object = object;
    }
}

interface MultiSet<T> {}
class LinkedMultiHashSet<T> implements MultiSet<T>, Iterable<T> {
    private ObjectContainer hashTable[];
    public LinkedMultiHashSet(int initialCapacity) {
        hashTable = new ObjectContainer[initialCapacity];
    }

    @Override
    public Iterator<T> iterator() {
        return null;
    }
}
