Read moreWhat is the difference between objects and primitives in Java?
Primitives are passed by value, i.e. a copy of the primitive itself is passed. Whereas for objects, the copy of the reference is passed, not the object itself . Primitives are independent data types, i.e. there does not exist a hierarchy/super class for them. Whereas every Object is descendent of class “Object”.
Read moreWhat is the difference between objects and primitives?
Primitive values can be stored in variables directly. Objects, on the other hand, are stored as references . A variable that has been assigned an object does not store that object directly, it stores the memory address of the location that the object exists at.

Primitive data types – includes byte , short , int , long , float , double , boolean and char . Non-primitive data types – such as String, Arrays and Classes (you will learn more about these in a later chapter)
Read moreAre objects non-primitive data types?
Non-Primitive data types refer to objects and hence they are called reference types. Examples of non-primitive types include Strings, Arrays, Classes, Interface, etc.
