When we create object from a class, it is created on stack or on heap. The existance of an object in memory (stack or heap) is called instance of an object.

Hence Instance and object is used interchangeably.

RE: What is the difference between instance and object?

A class is an Abstract Datatype which when instantiated sets aside memory which holds data in fields and references to the instructions for methods.

An instance of a Class is a section of heap memory set aside using the class's template to hold particular data and references back to the shared class instructions stored in the Stack. We access the start of that memory area by using the name of the instance. The runtime engine has calculated the offset from that location to go to the memory location where the individual data or method references are stored.

RE: What is the difference between instance and object?

When you create a custom type (class) in any language that class in OOP is called Object and when you create an istance of this class just as we create instance of built-in types e.g. (int a float b) it is called instance of the object.
