For this you have to know, what is Object actually... An Object within Object Oriented Programming is an instance of a Class. Objects (instances) are created from the Class using the keyword "new". You can create as many instances of a class as you would like. When a new Object is created, then memory will be allocated for the class in heap memory area, which is called as an instance and its starting address will be stored in the object in stack memory area.Now you can create a object of class like this.....ClassName clsname= new ClassName();
