Non-primitive data types - such as String, Arrays and Classes (you will learn more about these in a later chapter)

The main differences between primitive and non-primitive data types are: Primitive types in Java are predefined and built into the language, while non-primitive types are created by the programmer (except for String).

A variable's data type determines the values it may contain, plus the operations that may be performed on it. In addition to int, the Java programming language supports seven other primitive data types. A primitive type is predefined by the language and is named by a reserved keyword.
