java - 无法使用 yaml 方法从 java 对象中获取特定值

Question

我正在使用 yamlbeans 从 yaml 文件中获取数据。我得到以下响应 {x1=[{y1=z1}, {y2=z2}], x2=[{y1 =z1}, {y2=z2]}

现在我想获取 x1 的数据 y1，但我无法做到这一点。我正在使用以下代码进行读取操作

package com.mobileapp;

import java.io.FileReader;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import net.sourceforge.yamlbeans.YamlReader;

public class ReadDataWithYaml {

    public static void main(String[] args) { 

        try {

            YamlReader reader = new YamlReader(new FileReader("C:\\Users\\5521\\Desktop\\test.yml"));
            Object object = reader.read();
            System.out.println(object);
            Map<String, ArrayList<String>> map = (Map<String, ArrayList<String>>) object;
            System.out.println(map.get("x1"));
        } catch (Exception exception) {
            exception.printStackTrace();
        }
    }

}

    Yaml yaml1 = new Yaml();
    InputStream inputStream1 = Main.class.getClassLoader().getResourceAsStream("YourYaml.yaml");
    Map< String, Object> result = (Map< String, Object>) yaml1.load(inputStream1);
    for (Object name : result.keySet()) {
        System.out.println(result.get(name).toString());

    }

    String x= result.get("userInput").toString();
    System .out.println(""+x);
