Creating an instance of AtClient

To create an instance of AtClient, use one of the factory methods. Note: you must have the .atKeys file in the ~/.atsign/keys directory. You can generate a .atKeys file from using the Register CLI or Onboaring CLI if you already own the atSign.

String ATSIGN_STR = "@bob";
AtSign atSign = new AtSign(ATSIGN_STR);
AtClient atClient = null;
try {
    atClient = AtClient.withRemoteSecondary(atSign);
} catch (AtException e) {
    System.err.println(e);
    e.printStackTrace();
}
// use atClient

There are a number of other factory methods for creating an AtClient instance to suit your needs. See the image below.
