The main differences between primitive and non-primitive data types are:
Non-primitive data types are called reference types because they refer to objects.
Non-Primitive Data Types
Non-Primitive Data Types
Non-primitive data types are called reference types because they refer to objects.
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 ).
- Non-primitive types can be used to call methods to perform certain operations, whereas primitive types cannot.
- Primitive types start with a lowercase letter (like int ), while non-primitive types typically starts with an uppercase letter (like String ).
- Primitive types always hold a value, whereas non-primitive types can be null .
Examples of non-primitive types are Strings , Arrays , Classes etc. You will learn more about these in a later chapter.
