解析并提出数据{"lanes":[{"lane_id":1,"BN":{"id":2,"x":7.912986587157469,"y":-1.2400772299026166,"yaw":91,"description":"RoadPoint","mark_pose":0,"ahead_node":0,"post_node":0},"FN":{"id":4,"x":7.909954266287153,"y":1.2599283317576682,"yaw":91,"description":"RoadPoint","mark_pose":0,"ahead_node":0,"post_node":0},"shape":{"lane_type":"bezier","p1":2,"p2":0,"hdg":0,"length":2.5},"info":{"speed":0.3,"motion_type":1,"obstacle_avoid":true,"extra_cost":1,"qr_code":1,"infrared":false,"heading":0,"avoid_level":0}}],"task":{"taskId":"GcJ9p-MmkS","node":4,"taskType":"LIFT","action":11,"direction":0,"target":0},"type":"move","msgid":1}

该JSON字符串可以通过使用JSON解析库（如JSON.simple、Gson等）来解析。在Java中，使用Gson库可以很方便地将JSON字符串转换为对应的Java对象。具体代码如下：

import com.google.gson.Gson;

String jsonString = "{\"lanes\":[{\"lane_id\":1,\"BN\":{\"id\":2,\"x\":7.912986587157469,\"y\":-1.2400772299026166,\"yaw\":91,\"description\":\"RoadPoint\",\"mark_pose\":0,\"ahead_node\":0,\"post_node\":0},\"FN\":{\"id\":4,\"x\":7.909954266287153,\"y\":1.2599283317576682,\"yaw\":91,\"description\":\"RoadPoint\",\"mark_pose\":0,\"ahead_node\":0,\"post_node\":0},\"shape\":{\"lane_type\":\"bezier\",\"p1\":2,\"p2\":0,\"hdg\":0,\"length\":2.5},\"info\":{\"speed\":0.3,\"motion_type\":1,\"obstacle_avoid\":true,\"extra_cost\":1,\"qr_code\":1,\"infrared\":false,\"heading\":0,\"avoid_level\":0}}],\"task\":{\"taskId\":\"GcJ9p-MmkS\",\"node\":4,\"taskType\":\"LIFT\",\"action\":11,\"direction\":0,\"target\":0},\"type\":\"move\",\"msgid\":1}";

Gson gson = new Gson();
MyMessage myMessage = gson.fromJson(jsonString, MyMessage.class);

System.out.println(myMessage.getLanes());
System.out.println(myMessage.getTask());
System.out.println(myMessage.getType());
System.out.println(myMessage.getMsgid());

其中，`MyMessage`是一个自定义的Java类，用于存储解析后的数据。在该类中，需要定义与JSON字符串中各个字段对应的属性。例如，`lanes`字段对应的是一个`List<Lane>`类型的属性，`task`字段对应的是一个`Task`类型的属性，`type`和`msgid`字段对应的是`String`类型的属性。在解析时，使用`fromJson`方法将JSON字符串转换为`MyMessage`对象。通过调用对象的各个属性，即可获取相应的数据。

解析并提取其中显示出数据{"lanes":[{"lane_id":1,"BN":{"id":2,"x":7.912986587157469,"y":-1.2400772299026166,"yaw":91,"description":"RoadPoint","mark_pose":0,"ahead_node":0,"post_node":0},"FN":{"id":4,"x":7.909954266287153,"y":1.2599283317576682,"yaw":91,"description":"RoadPoint","mark_pose":0,"ahead_node":0,"post_node":0},"shape":{"lane_type":"bezier","p1":2,"p2":0,"hdg":0,"length":2.5},"info":{"speed":0.3,"motion_type":1,"obstacle_avoid":true,"extra_cost":1,"qr_code":1,"infrared":false,"heading":0,"avoid_level":0}}],"task":{"taskId":"GcJ9p-MmkS","node":4,"taskType":"LIFT","action":11,"direction":0,"target":0},"type":"move","msgid":1}

该数据是一个JSON格式的字符串，其中包含以下信息：

1. lanes：一个包含一个元素的数组，该元素表示车道信息，包括车道id、起始点和结束点的信息、车道形状信息和其他附加信息。
2. task：表示任务信息，包括任务id、任务类型、任务动作等。
3. type：表示消息类型，此处为“move”。
4. msgid：表示消息id。

具体包含的数据如下：
