Netbeans - 读取src文件夹中的数据文件 [英] Netbeans - Reading a data file in src folder

问题描述

我有一个扫描程序正在尝试读取src文件夹中名为info.data的文件。我在线程main中得到Exception java.io.FileNotFoundException：info.data（系统找不到指定的文件）。我应该在扫描仪中放置什么地址？

I have a scanner that's trying to read a file named info.data in the src folder.I get Exception in thread "main" java.io.FileNotFoundException: info.data (The system cannot find the file specified). What's the address I should put in the scanner?

推荐答案

如果输入文件始终是应用程序的一部分（即你也放了这将在以后的.jar文件中）你应该使用 getResourceAsStream（）来读取它的内容。

If the input file is always part of your application (i.e. you also put this into the .jar file later) you should use getResourceAsStream() in order to read its contents.

InputStream in = getClass().getResourceAsStream(filename);
Scanner scanner = new Scanner(in);
