Which jar to use for SQLite latest version 3.13.0

I have downloaded latest SQLite version 3.13.0 from SQLite download page at https://www.sqlite.org/download.html. As per release history, this version is dated 18.05.2016
I am developing an application which uses Java to connect to SQLite database. I have downloaded latest available jar "sqlite-jdbc-3.8.11.2.jar" at https://bitbucket.org/xerial/sqlite-jdbc/downloads. This jar is dated 03-10-2015
My DAO class is as follows :
import java.sql.*;
public class AccountDao {
private Connection conn=null;
public AccountDao() throws SQLException {
try {
Class.forName("org.sqlite.JDBC");
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
conn = DriverManager.getConnection("jdbc:sqlite:C:\\Users\\sony\\Documents\\rough.db");
}
I am getting the following error :
