A class is nothing more than a type. An object is an instance of a type. The class merely defines how object's of the type will behave; it classifies the object.
Compare with a built-in type such as int. An int is a type while a variable of type int is an instance of the type. The type determines how the variable will behave; how its memory is laid out; what operations apply to the type and how those operations will be implemented. An object is simply an extension of that concept, allowing the programmer to define much more complex types from any combination of pre-existing types.

How oops concept is implemented in java?
OOP stands for Object Oriented Programming. Everything in Java is an Object. Any class you create extends the Object class by default thereby making everything in Java an object. Moreover, you can use features like Inheritance, Polymorphism, Encapsulation etc which are OOP concepts thereby making Java an Object Oriented Programming Language
What is object in java programming?
In java object is an instance of a class. Objects are created using the new keyword. When you use the new keyword along with a class name, an object of that class would get created. Ex: Ferrari obj = new Ferrari(); Here a new object of Ferrari gets created. A constructor of the class Ferrari would get invoked during the object creation.
What defines the behavior of an object in object-oriented programming and how is it implemented within the programming paradigm?
In object-oriented programming, the behavior of an object is defined by its methods, which are functions that describe what the object can do. This behavior is implemented by creating classes that define the structure and behavior of objects, and then creating instances of those classes to use in the program. The methods within the class determine how the object interacts with other objects and data in the program.
What is the size of an object of empty class?
That would depend on the programming language; even for the same language, it may vary for specific implementations. Usually such an object should just use a few bytes.
What is object oriented language in c plus plus?
C++ enables object oriented programming through the use of classes, where an object is an instance of a class. A class is essentially a data type, one that can store information (much like an int stores a value) and that provides an interface to that information.
What class is the super class for ALL Java classes?
The Object class, in the java.lang package, sits at the top of the class hierarchy tree. Every class is a descendant, direct or indirect, of the Object class. Every class you use or write inherits the instance methods of Object. You need not use any of these methods, but, if you choose to do so, you may need to override them with code that is specific to your class
Can instance methods replace class methods in programming?
No. never. An instance method cannot replace a class method because: Instance Methods - are normal methods that are linked to a class object instance Class Methods - are static methods that are not linked to any class object. These methods are not interchangeable and will create too many issues if we try to use one in place of the other.
How many types of classes in c?
There are no classes in a C program.C is not a object oriented programming language only object oriented programming language has classes c++ is a object oriented programming language.Class can be defined as a blueprint from which individual objects are created.eg:Car is a Class BMW is an Object of that class.Join http://www.c-madeeasy.blogspot.com for c programming source codes,tutorials and advanced programming advice.
Is C or Cpp better to use for game programming?
C++ is basically an object-oriented version of C (with a whole new set of capabilities). Most video games seem to lend themselves to an object-oriented. Class Character Class Player inherits from Character Class Enemy inherits from Character Class EasyEnemy inherits from Enemy Class HardEnemy inherits from Enemy etc.
Why did computer scientists introduce object - oriented programming?
If you work a while with object-oriented programming, you'll notice that it offers huge benefits over the traditional approach. In fact, you would rather not use a programming language that doesn't have at least the option of object-oriented programming, if you have the choice.
What kind of written language did Delphi use?
Delphi used a programming language called Object Pascal for its written language. Object Pascal is an extension of the Pascal language that includes object-oriented programming features.
Thw importance of ASP.net?
Object Oriented Programming is a subset of structured programming. After objects are created in a program, you use those objects and their methods to operate the program. In structured programming, you have a program with many methods in which you can use. One difference between structured programming and object-oriented programming is that structured programming uses the data that is given to them through parameters, while in object-oriented programming, the methods act upon the object's data (fields). This makes programming much easier because the fields are all there and you do not have to make sure that the correct field is passed to the correct method. All you have to do is call which field you want to work with.
