将firebase中的父密钥存储到arraylist中并打印出来

import com.google.firebase.FirebaseApp;
import com.google.firebase.FirebaseOptions;
import com.google.firebase.auth.FirebaseAuth;

import java.util.ArrayList;

public class FirebaseKeyExample {

    public static void main(String[] args) {
        // 步骤1：导入Firebase SDK
        // 导入相应的Firebase SDK，如firebase-admin-sdk或firebase-client-sdk

        // 步骤2：初始化Firebase
        FirebaseOptions options = new FirebaseOptions.Builder()
                .setCredentialsPath("path/to/serviceAccountKey.json")
                .build();
        FirebaseApp.initializeApp(options);

        // 步骤3：获取父密钥
        String parentKey = FirebaseAuth.getInstance().getFirebaseAuthParentKey();

        // 步骤4：存储到ArrayList并打印出来
        ArrayList<String> keysList = new ArrayList<>();
        keysList.add(parentKey);
        System.out.println("父密钥列表：" + keysList);
