Reference a Text File with relative path in Java with the IntelliJ IDEA

Question

I have a program that reads numbers from a .txt file. My problem is where to place this file, or how to reference it with a relative path to make this file accessible without using the absolute path.

Answer 1

When you try to open a file, it takes your current working path. For example this working tree:

Project
|->src
|   |-->MyClass.java
|   |-->MyFile1.txt
|->res
   |->files
     |-->MyFile2.txt

You can use

new File("MyFile1.txt");

for MyFile1, or

new File("./res/files/MyFile2.txt");

for MyFile2.
