如何初始化一个包含空地址数组的结构？

public class AddressStructure {
    private Address[] addresses;

    public AddressStructure(int size) {
        addresses = new Address[size]; // 初始化地址数组，大小为指定的size
    }

    public void addAddress(int index, Address address) {
        addresses[index] = address; // 向指定位置添加地址
    }

    public Address getAddress(int index) {
        return addresses[index]; // 获取指定位置的地址
    }

    // 其他操作方法...

    public static void main(String[] args) {
        AddressStructure structure = new AddressStructure(10); // 创建一个大小为10的地址结构

        // 添加地址
        structure.addAddress(0, new Address("Address 1"));
        structure.addAddress(1, new Address("Address 2"));

        // 获取地址
        Address address1 = structure.getAddress(0);
        Address address2 = structure.getAddress(1);

        System.out.println(address1);
        System.out.println(address2);
    }
}

class Address {
    private String address;

    public Address(String address) {
        this.address = address;
    }

    @Override
    public String toString() {
        return address;
    }
}
