在Java中使用e.printStackTrace() [英] Using e.printStackTrace() in Java

问题描述

这可能是一个新手问题，但希望您能帮助我. :)我有这样的东西:

This is probably a newbie question, but hope you can help me. :) I have something like this:

try
{ 
//try to do something there
}
catch (IOException e)
{
//handle the exception 
e.printStackTrace();
}

我正在使用NetBeans IDE，由于某种原因，printStackTrace的下划线标有波浪线.当我按Alt + Enter时，提示应删除Throwable.printStackTrace().这是什么意思?谁能提供更多的见解，这可能意味着什么?还是我可以忽略这个?

I am using NetBeans IDE and for some reason the printStackTrace is underlined in a squiggly line. When I press Alt+Enter, it says Throwable.printStackTrace() should be removed. What does this mean? Could anyone give more insight as what this may mean? Or can I ignore this?

谢谢！

推荐答案

这只是一个建议.在eclipse中很好-我相信这只是IDE告诉您，还有其他一些更常规的方法可以做到这一点. 我发现它对于调试很有用，并且应该在发生致命错误时告诉用户使用调试模式(例如控制台开关-d)来收集这些日志.

It is just a recommendation. In eclipse it is fine - I believe it is just the IDE telling you that there are more conventional methods of doing it, like some of the other answers. I find that it is useful for debugging, and that you should tell users when a fatal error is going to occur, to use a debug mode (like a console switch -d) to collect these logs.
