Detailed explanation-1: -In languages that create objects from classes, an object is an instantiation of a class. That is, an object is a member of a given class with specified values rather than variables. For example, in a non-programming context, “bird” could be a class and your pet bird Polly an object of that class.
Detailed explanation-2: -Explanation: An object is instance of its class. It can be declared in the same way that a variable is declared, only thing is you have to use class name as the data type.
Detailed explanation-3: -A class can create objects of itself with different characteristics and common behaviour. So, we can say that an Object represents a specific state of the class. For these reasons, an Object is called an Instance of a Class.
Detailed explanation-4: -An object is a member or an “instance” of a class. An object has a state in which all of its properties have values that you either explicitly define or that are defined by default settings.
Detailed explanation-5: -Object instance is a specific occurrence of an object. For example, a specific mail message document is an instance.
