An object is an instance of a class. It is an entity created as per the specifications and behaviour coded in the class. Say you have a class Wallet that defines a Wallet (Purse) . And you have specified in the class like it have 2 compartments, 2 pouches, one notepad. Also you have coded the behaviour of the Wallet is to keep Money, take Money and money Left.

Similarly you can create any number of wallets using the Wallet Class as and when required. read less

Before defining the object, i would like you to remind the built in data types (int, float, char etc) and user defined data types (Struc, Union, Class etc). To identify any data types, we declare variable (Variable is an identifier). For ex- Int x, y; Float a, b; this x and y or and b identify or point out the "type of data or characteristics of data" stored in it. In similar way, object is another variable of type Class which can represent any real world entity or its attribute. For example, Apple, Orange, Banana all comes under one category Fruit. It has many attribute like color, size, taste etc. To simplify the representation of fruits, we defines user built data type called Class. Declaration: Class Fruit { String color, taste; / /These are the properties of fruit. float price, amount; } Object declaration // In similar way of user defined data type like Int a, b; Fruit apple, orange, banana; // these are the variables/instances of fruit. read less
