有没有办法创建包含数据和被覆盖的toString方法的匿名对象数组？

interface DataHolder {
    String getData();
    String toString();
}

public class AnonymousObjectArrayExample {
    public static void main(String[] args) {
        DataHolder[] dataHolders = new DataHolder[]{
            new DataHolder() {
                private String data = "Data 1";

                @Override
                public String getData() {
                    return data;
                }

                @Override
                public String toString() {
                    return "Custom toString: " + data;
                }
            },
            new DataHolder() {
                private String data = "Data 2";

                @Override
                public String getData() {
                    return data;
                }

                @Override
                public String toString() {
                    return "Custom toString: " + data;
                }
            }
        };

        for (DataHolder holder : dataHolders) {
            System.out.println(holder.toString());
        }
    }
}

Custom toString: Data 1
Custom toString: Data 2
