Answer 1

The simplest way to get the current directory of a java application is :

System.out.println(new File(".").getAbsolutePath());

Like that you can consider the given path as the root of your application.

Answer 2

Read the file as a resource. Put it somewhere in the src. For instance

src/resources/myresource.txt

Then you can just do

InputStream is = getClass().getResourceAsStream("/resources/myresource.txt");

Note: if you are using maven, then you are more accustomed to something like this

src/main/resources/myresource.txt

With maven, everything in the main/resources folder gets built to the root, so you would leave out the resources in your path

InputStream is = getClass().getResourceAsStream("/myresource.txt");
