Try:
尝试：
System.out.println(sfdate.format(date));
As your last line rather than the one that you have at current.
作为你的最后一行，而不是你目前拥有的那一行。

为什么要创建时间戳？当你可以：
SimpleDateFormat sfdate = new SimpleDateFormat("MM/dd/yyy HH:mm:ss a");
Date date = new Date();
date = sfdate.parse(dateString);
System.out.println(sfdate.format(date) );
Output:

Timestamp.toString()prints to a specific format: yyyy-mm-dd hh:mm:ss.fffffffff. The Timestamp object itself should be correct, if that's all you are looking for.
Timestamp.toString()打印为特定格式：yyyy-mm-dd hh:mm:ss.fffffffff. Timestamp 对象本身应该是正确的，如果这就是您要查找的全部内容的话。
If you then want to define another format in order to print it as you like, that would require you to format Dateobject, using an appropriate pattern for the output format you are looking for.
如果您想定义另一种格式以便按您的喜好打印它，则需要您格式化Date对象，使用适合您正在查找的输出格式的适当模式。

What you're seeing is the result of Timestamp.toString(). The actual valuein the Timestamp object instance is valid.
你看到的是结果Timestamp.toString()。Timestamp 对象实例中的实际值是有效的。
If you're getting an error in a subsequent SQL operation, please post that error along with the code you're using.
如果您在后续 SQL 操作中遇到错误，请将该错误与您使用的代码一起发布。
