我有一个记录，想向它添加默认构造函数。

public record Record(int recordId) {
   public Record {

   }
}

但它用int参数创建了构造函数。

public final class Record extends java.lang.Record {
    private final int recordId;
    public Record(int);
    //other method
}

我们如何向记录添加默认构造函数？

这可能是一个重复的这个，但没有得到那边妥善解决。我有如下对象，

var replyDataObj = {

                  "department": {
                    "name": getCache("departmentName")
                  },
                  "subject": replyEmailSubject,  
                  "payload": {
                    "email": {
                      "contents": {
                        "content": [
                          {
                            "type": "html",
                            "value": replyEmailContent
                          }   
                        ]
                      },
                      "emailAddresses": {
                        "from": fromEmailId,
                        "to": {
                          "address": [
                            toEmailId
                          ]
                        }        
                      }
                    }
                  }  
            }

我想根据 cc 字段是否存在，动态地将以下键值添加到 'emailAddresses' 键，

"cc": {
         "address": [
           ccEmailId
          ]
      }  

所以它看起来像，

var replyDataObj = {

              "department": {
                "name": getCache("departmentName")
              },
              "subject": replyEmailSubject,  
              "payload": {
                "email": {
                  "contents": {
                    "content": [
                      {
                        "type": "html", …
