setting url SQLite and java

Question

I'm working on java swing app which uses SQLite database.

The app works fine on my device, I now want to distribute the app- how do I set the url in the connection statement so that it works on all devices?

My current statement is:

Connection conn = DriverManager.getConnection(
     "jdbc:sqlite:C:\\Users\\Pankaj4011\\Desktop\\login\\admin.sqlite" );

On another device it shows this error:

java.sql.SQLException:path to 
    C:\\Users\\Pankaj4011\\Desktop\\login\\admin.sqlite : 
    c:\Users \Pankaj4011 does not exist`
