What are user-defined objects in Java?

A deep class is defined as a class in which, at least one of its fields is a user defined class . Creating a deep class to be interoperability ready, requires defining all its deep fields as fields that will be stored to the space, using its matching Java objects types.

Class Code (User Defined Java Class) Add your defined Java code directly in the Processor tab in the Class code panel . You can create additional tabs for more code blocks by right-clicking and selecting Add new. This menu also includes options for copying a tab, setting a transformation class, or removing a class type.8 Eki 2021

User-defined classes are common to object-oriented programming and are used to represent objects whose data can be protected, initialized, and accessed by a specific set of procedures .

In Java, all classes (built-in or user-defined) are (implicitly) subclasses of Object . Using an array of Object in the List class allows any kind of Object (an instance of any class) to be stored in the list. However, primitive types (int, char, etc) cannot be stored in the list.
