如何在NetBeans之外写入文本文件 [英] how to write to text file outside of netbeans

问题描述

我很确定有人已经问过这个问题，但我找不到.我该如何写一个文本文件，以便当我从netbeans构建项目时，当将文件构建到.jar中时，仍然可以写该文件. 我在读取文件到.jar时也遇到了问题，但发现我可以使用InputStream和BufferedReader.除了写作，还有什么可以做到的吗? 这就是我正在使用的:

I'm pretty sure someone has already asked this but i Can't find it. How can I write to a text file so that when i build the project from netbeans it'll still be able to write the file when its built into the .jar. I was also having a problem reading file to .jar but found out i could use InputStream and BufferedReader. Is there something that can do this but with writing? This is what I was using:

 printf=new PrintWriter(new File("Names.txt"));

但这不适用于在netbeans之外编写. 该文件位于我要写入的jar文件的类中.

but that doesn't work for writing outside of netbeans. The file is inside the classes of the jar file that I want to write to.

推荐答案

给出绝对路径，例如是否要在d:/someFolder

Give absolute path like if you want it in d:/someFolder

printf=new PrintWriter(new File("d:/someFolder/Names.txt"));
