What are object? 

Objects are key to understanding object-oriented technology. Look around right now and you'll find many examples of real-world objects: your dog, your desk, your television set, your bicycle.

Real-world objects share two characteristics: They all have state and behavior. Dogs have state (name, color, breed, hungry) and behavior (barking, fetching, wagging tail). Bicycles also have state (current gear, current pedal cadence, current speed) and behavior (changing gear, changing pedal cadence, applying brakes). Identifying the state and behavior for real-world objects is a great way to begin thinking in terms of object-oriented programming.

hi singh an Object, or UFO, is any flying object or phenomenon that cannot be identified by the observer. Various studies show that after investigation, the majority of UFOs are usually identified, and are relabeled IFOs or Identified Flying Objects. Therefore, some stricter definitions reserve the label "UFO" for only those instances where the objects remain unexplained after a proper investigation

Take a minute right now to observe the real-world objects that are in your immediate area. For each object that you see, ask yourself two questions: "What possible states can this object be in?" and "What possible behavior can this object perform?". Make sure to write down your observations. As you do, you'll notice that real-world objects vary in complexity; your desktop lamp may have only two possible states (on and off) and two possible behaviors (turn on, turn off), but your desktop radio might have additional states (on, off, current volume, current station) and behavior (turn on, turn off, increase volume, decrease volume, seek, scan, and tune). You may also notice that some objects, in turn, will also contain other objects. These real-world observations all translate into the world of object-oriented programming.

An object in grammar is a sentence element and part of the sentence predicate. It denotes somebody or something involved in the subject's "performance" of the verb. As an example, the following sentence is given: In the sentence "Bobby kicked the ball", "ball" is the object.

well sharad, In the programming paradigm, object-oriented programming, an object is an individual unit of run-time data storage that is used as the basic building block of programs. Objects are the things you think about first in designing a program and they are also the units of code that are eventually derived from the process. In between, each object is made into a generic class of object and even more generic classes are defined so that objects can share models and reuse the class definitions in their code.

well, 1). A computer representation of something that a user can work with to perform a task. An object can appear as text or an icon.

2). A collection of data and member functions that operate on that data, which together represent a logical entity in the system.

Objects don't just appear out of thin air. Just as a contractor needs access to an architect's blueprint before creating a building based on that blueprint, a running program needs access to a class before creating objects based on that class.
Declaring classes

A class is a source code blueprint for objects. That blueprint specifies each object's behaviors and state variables. Use the following Java syntax to declare a class in source code:

[ 'public' ] [ ( 'abstract' | 'final' ) ] 'class' class_name
'{'
// behaviors and state variables are declared between the { and } characters
'}'



To introduce a class declaration, specify keyword class and follow it with an identifier -- represented by class_name -- that names the class. The identifier cannot be a reserved word. For example, class Account introduces a class declaration where Account names the class. (By convention, class names are capitalized.) Keywords public and/or abstract or final -- but not abstract and final, because the resulting class would be meaningless -- can optionally precede keyword class.

object is an entity that can store data and, send and receive messages. an instance of a class.

Hi sharad,

In the programming paradigm, object-oriented programming, an object is an individual unit of run-time data storage that is used as the basic building block of programs
An object is an instance of a character on the display list.

A computer representation of something that a user can work with to perform a task. An object can appear as text or an icon. (2) A collection of data and member functions that operate on that data, which together represent a logical entity in the system.
An instance of an object class
In object-orientated programming, a self-contained entitiy that consists of both data and manipulation procedures
