Creating and Manipulating JSON Objects with FastJSON in Java

The author announces a video tutorial on basic operations with JSON objects, recorded spontaneously without extensive preparation, and invites feedback.

The video series includes three topics: an introductory overview of the FunTester testing framework, obtaining HTTP request objects, and sending requests with response parsing.

Due to platform length limits, the content is split into two videos: one covering JSON object creation and data addition, and another covering data retrieval and formatted output. A code snippet shows how to replace escaped forward slashes ("\\/" -> "//") in response strings.

For deeper understanding of shallow vs. deep copying and console output methods, the author refers readers to previous articles on JVM heap analysis and JSON console formatting.

Demo code:

package com.fun;

import com.alibaba.fastjson.JSON;
import com.alibaba.fastjson.JSONObject;
import com.fun.frame.SourceCode;

public class Fun extends SourceCode {
    public static void main(String[] args) {
        // Example JSON string
        String jsonstr = "{\"22\":\"fdskjflsj\",\"221\":{\"2\":3243,\"213\":213243,\"32\":321243},\"2\":323333,\"222\":false,\"array\":[{\"2\":3243,\"213\":213243,\"32\":321243},{\"2\":3243,\"213\":213243,\"32\":321243},{\"2\":3243,\"213\":213243,\"32\":321243}]}";
        JSONObject jsonObject1 = JSON.parseObject(jsonstr);
        jsonObject1.put("array", "1/2");
        // output(jsonObject1.equals(json));
        output(jsonObject1);
        output(jsonObject1.getBooleanValue("222"));
        output(jsonObject1.getJSONObject("221"));
    }
}
