Can you list data types in Java other than primitive types?

In Java, besides the basic primitive types (int, boolean, char, byte, short, long, float, double), the following data types exist:

  • Wrapper classes for primitives: Integer, Boolean, Character, Byte, Short, Long, Float, Double — allow primitives to be used as objects.
  • Strings (String) — a class for working with textual data.
  • Arrays — objects containing a set of elements of the same type.
  • Collections (List, Set, Map, etc.) — interfaces and classes for storing and managing groups of objects.
  • User-defined classes — any classes you create to model data.
  • Interfaces — describe behaviors that classes can implement.

Example of using a wrapper class:

Integer number = 10; // instead of int
String text = "Sample string";
List<String> list = new ArrayList<>();
list.add(text);

Thus, data types in Java are divided into primitive and reference (object) types.
