Create a custom field in the control panel. You can specify it's type, default value, visibility, permissions, etc.

The custom field will be available in that portion of the control panel it belongs to (i.e. if you create a User custom field, it is available in the custom fields page of user details).

Programmatically you can access this value through a number of different ways - directly via the API, but also as getter methods on the object type the custom field belongs. So your User custom field can be accessed by calling userInstance.getExpandoBridge().getAttribute("my custom field name") and casting the result to your expected type. You can also set the value in a similar manner.

QED.

you can get custom attribute through this way

expandoBridge = user.getExpandoBridge();

 String attributeValue = (String) expandoBridge.getAttribute("Custom_Attr_name");
