Java-主文本文件的相对路径？

Question

I was wondering how to specifiy a relative path name to a text file that is stored in my src folder of a java project. I would like to store a string with the path of this text file. For example if I had example.txt located in the src folder of my java project how would I go about finding its relative path? I am also doing this in my main so I'm having trouble using .getResource(). How would I do this? Thanks.

My files path is as followed from the properties in eclipse /MyProject/src/data.txt

I've tried:

String path = "/MyProject/src/data.txt";

But that doesn't work?

Answer 1

If you are using eclipse, place your text file in the root of the project folder, outside the /src and /bin folders. It should be now accessible via a relative path directly.

If you want to access a file in src folder, you have to append the /src/ prefix before the file path/name

Answer 2

在文件路径/名称前使用src/前缀。

String path = "src/data.txt"; 

Answer 3

The path is relative to the directory you execute the "java" command.eg

 /opt/projects/myproject>$ java -cp <whatever your classpath is that contains your class files> com.mycompany.mypackage.MyJavaClass

in this case the MyJavaClass would find files relative to the directory
/opt/projects/myproject

There is another way to do this if you like: you can use load resources, which are found via the classpath mechanism.

 getClass().getResource("foo.txt");
