问题描述

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您应用程序的一部分(即您稍后也将其放入 .jar 文件中)，您应该使用 getResourceAsStream() 以读取其内容.

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);
