创建自定义数组 class

Question

I have created a custom class called ObjectContainer, and am trying to create an array containing those objects. However, when i try to instantiate the array with new ObjectContainer[initialCapacity];it gives me Generic Array creation error. I thus found an answer online that suggests casting an object to it, which i have done

(ObjectContainer[]) new Object[initialCapacity];

However, i now get another error

java.lang.ClassCastException: class [Ljava.lang.Object; cannot be cast to class [LHashSet$ObjectContainer;
([Ljava.lang.Object; is in module java.base of loader 'bootstrap';
[LHashSet$ObjectContainer; is in unnamed module of loader 'app')

What do i do to create an ObjectContainer array?

Edit: Using

(ObjectContainer[]) new ObjectContainer[initialCapacity];

Gives me Generic array creation error.

ObjectContainer class:

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

This is implemented within a HashSet class:

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

       hashTable = (ObjectContainer[]) new ObjectContainer[initialCapacity];
    }
}

Answer 1

Replace

(ObjectContainer[]) new Object[initialCapacity];

by

new ObjectContainer[initialCapacity];

as Object cannot be cast to ObjectContainer

EDIT 1: With provided class, the following code does compile

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;
    }
}

EDIT 2: The following code does compile

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;
    }
}
