What and how should I connect to work with sqlite3 in java?

Question

Java

Need to work with sqlite3. I try to connect to the database, but errors.

public static void connect_to_db ( ) {
                try {
                        Class.forName ( "org.sqlite.JDBC" );
                        System.out.println ( configPath );
                        conn = DriverManager.getConnection ( "jdbc:sqlite:" + configPath );
                } catch ( SQLException e ) {
                        System.out.println ( e.getMessage() );
                } catch ( ClassNotFoundException e ) {
                        System.out.println ( "class.forName: " + e.getMessage ( ) );
                }
        }
