如何使用javax.json.*在Java中写出JSON数据？

import javax.json.Json;
import javax.json.JsonBuilderFactory;
import javax.json.JsonObject;
import javax.json.JsonObjectBuilder;

public class JsonExample {
    public static void main(String[] args) {
        // 创建JsonBuilderFactory对象
        JsonBuilderFactory factory = Json.createBuilderFactory(null);

        // 创建JsonBuilder对象
        JsonObjectBuilder builder = factory.createObjectBuilder();

        // 添加键值对
        builder.add("name", "John Doe");
        builder.add("age", 30);
        builder.add("isStudent", false);

        // 构建JSON对象
        JsonObject jsonObject = builder.build();

        // 将JSON对象转换为字符串
        String jsonString = jsonObject.toString();

        System.out.println(jsonString);
    }
}

{"name":"John Doe","age":30,"isStudent":false}
