Read moreShould I use primitives in Java?
Instead of create variables using new, Java can use primitive types to create automatic variables that are not references . The variables hold the value, and it’s place on the stack so its much more efficient.16 Tem 2017
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.

Read moreWhat are some examples of primitive types?
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 moreWhy are primitives not objects?
Since the primitive data types consume less memory and can be accessed faster , they are not objects. The equivalent Wrapper classes are also available in java like “Integer” “Short” etc. They can be used as objects if you want. However, the wrapper classes will be stored in Heap and they are slow.17 Mar 2012
