What data types are primitive What about reference data types?

Primitive vs.

Primitive data structure is a kind of data structure that stores the data of only one type. Non-primitive data structure is a type of data structure that can store the data of more than one type. Examples of primitive data structure are integer, character, float.

Variables in Java are classified into primitive and reference variables. From the programmer’s perspective, a primitive variable’s information is stored as the value of that variable, whereas a reference variable holds a reference to information related to that variable .
