Categories of Data Types

All data values,
including functions, are objects.
Thus, all data types are reference types. |
There are two broad
categories of data types: primitive types and reference types. The primitive types
include the numeric types (double, int, char) and boolean.
The values of primitive types are immutable and are not instances of
classes. Reference types are
classes. Thus, any object or
instance of a class is of a reference type. These include strings, arrays, lists, maps, and so forth. |
