## Connect


```java
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;


public class ConnectCloudExample {
    public static void main(String[] args) throws SQLException {
        String token = System.getenv("TDENGINE_CLOUD_TOKEN");
        String jdbcUrl = "jdbc:TAOS-RS://cloud.taosdata.com:8085?usessl=true&token=" + token;
        Connection conn = DriverManager.getConnection(jdbcUrl);
        System.out.println("Connected");
        conn.close();
    }
}
```

The client connection is then established. For how to write data and query data using the connection, please refer to [usage-examples](https://docs.tdengine.com/reference/connector/java#usage-examples).
