问题
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?
回答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
回答2:
Use the src/ prefix before the file path/name.
String path = "src/data.txt";
回答3:
The path is relative to the directory you execute the "java" command.e.g.
/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");
