Where is the location for putting SQLite db file in JAVA project?

I am using eclipse for JAVA development in Windows 7 and I put my project in D:\workspace.

The following code is trying to connect to a SQLite database, While the jdbc address is jdbc:sqlite:sample.db, where is the location that JAVA is looking for sample.db ?

public class Sample{
  public static void main(String[] args) throws ClassNotFoundException{

    Class.forName("org.sqlite.JDBC");

    Connection connection = null;
    try{
        connection = DriverManager.getConnection("jdbc:sqlite:sample.db");
        System.out.println("I got connection.");
    }catch(SQLException e){
        System.out.println(e.getMessage());
    }
  }
}

I have see there is example for using absolute paths, But I'd like to know where to put the DB file while I use Relative path.

Also, Does the file location be difference if I put the Class in some package ?
