Is int a reference type in Java?

Types in Java are divided into two categories—primitive types and reference types. The primitive types are boolean , byte , char , short , int , long , float and double . All other types are reference types, so classes, which specify the types of objects, are reference types.

A reference is an address that indicates where an object’s variables and methods are stored . You aren’t actually using objects when you assign an object to a variable or pass an object to a method as an argument. You aren’t even using copies of the objects. Instead, you’re using references to those objects.

Reference types are any instantiable class as well as arrays : String , Scanner , Random , Die , int[] , String[] , etc. Reference variables store addresses to locations in memory for where the data is stored.
