Object

Objects are the basic run-time entities of an object oriented system. They may represent a person, a place or any item that the program must handle."An object is a software bundle of related variable and methods.""An object is an instance of a class"

A class will not occupy any memory space. Hence to work with the data represented by the class you must create a variable for the class, that is called an object.

When an object is created using the new operator, memory is allocated for the class in the heap, the object is called an instance and its starting address will be stored in the object in stack memory.

When an object is created without the new operator, memory will not be allocated in the heap, in other words an instance will not be created and the object in the stack contains the value null.

When an object contains null, then it is not possible to access the members of the class using that object.

Example :-

class Employee { }

Syntax to create an object of class Employee:

Employee objEmp = new Employee();
