Differentiate between Primitives and Objects

Everything in Java is an "Object", as every class by default inherits from class

"Object", except a few primitive data types, which are there for efficiency reasons.

Primitive Data Types

Primitive Data types of java

boolean, byte 1 byte

char, short 2 bytes

int, float 4 bytes

long, double 8 bytes

Primitive data types are normally used for local variables, parameters and instance variables (properties of an object)
Primitive datatype are located on stack and we can only access their value whereas objects are located on heap and we have a reference to these objects
Additionally primitive data types are always passed by value while objects are always passed by reference in java. There is no C++ like methods

- void someMethod (int &a, int & b) // not available in java
