Object - When there is an value.
int[] arr={1,2,3};
Instance - when there is a declaration for class with 'new'.
String arr=new String("test");
A obj2 = new A(); //this is the object instance with occupy memory for this..
For user defined classes, object and instances are same.
Class methods are the member functions that act upon member variables. An object is an instance of a class. C does not support object-oriented programming, but C++ does.
Instantiation is creating the instance of the variable/object . While Initialization is to provide the variable with some value. int i; // i is an instance of an integer i=10; //initialised with the value 10
An override is the specialisation of a virtual function. The new keyword instantiates an instance of an object in dynamic memory and returns a reference to that object (or null if the object could be instantiated). Both are used in C++, but not C.
The difference between roughness and flatness is that one, flatness, is the shape of an object. Roughness is the surface or texture of an object.
A floating object can be moved independently of the surrounding text characters.
An object is an INSTANCE of a class. Human is a class, while YOU are a person, an instance of Human class, but YOU do not represent the entire human class. Or, a class provides the abstraction, and an object is a typical example of that abstraction. Classes provide a blue print to build a real instance of an object.

Class methods are the member functions that act upon member variables. An object is an instance of a class. C does not support object-oriented programming, but C++ does.
An instance variable is typically associated with an object instance of the class whereas class variable is not associated with any object instance. Static variables are referred to as class variables while non-static regular variables are called instance variables. Simply put, you will have as many instances of the instance variable as there are object instances. i.e., if there are 10 instances of an object, you will have 10 instances of that instance variable as well. But, there will be only one instance of the static or class variable. Instance variables are accessed as follows: objname.variableName; Class variables are accessed as follows: ClassName.variableName;

Well, in one instance matter is the atoms making up every object on Earth and beyond it, measured by mass, volume, and density. In another instance, things that matter are things that are important. There is a large difference between the meaning of the words.
