INTRODUCTION: THE THINGS THAT MATTER Sherry Turkle I grew up hoping that objects would connect me to the world. As a child‚ I spent many weekends at my grandparents’ apartment in Brooklyn. Space there was limited‚ and all of the family keepsakes—including my aunt’s and my mother’s books‚ trinkets‚ souvenirs‚ and photographs—were stored in a kitchen closet‚ set high‚ just below the ceiling. I could reach this cache only by standing on the kitchen table that I moved in front of the closet. This

The main difference between them is that a class can implement more than one interface but can only inherit from one abstract class Similarities -both does not allow object to be created -both contain abstract method that must be override -both exhibit a polymorphic behavior Feature | Interface | Abstract class | Multiple inheritance | A class may inherit several interfaces. | A class may inherit only one abstract class

they were an infant they had to develop the knowledge that when you don ’t see something it still exists on earth. Technically‚ infants must be looking at a magic show everyday for months. Piaget coined the term object permanence in 1954 to describe the understanding that objects continue to exist‚ even when they cannot be directly seen‚ heard or touched. While conducting an experiment on his son as Piaget often did he found that his son did not reach for a toy that he had hidden with a cover

JavaScript Objects Everything is an Object • In JavaScript almost everything is an object. Even primitype datatypes (exept null and undefined) can be treated as objects. • Booleans can be objects or primitive data treated as objects • Numbers can be objects or primitive data treated as objects • Strings are also objects or primitive data treated as objects • Dates are always objects • Maths and Regular Expressions are always objects • Arrays are always objects • Even functions are always

process architecture design should consider which processes are responsible for which use-cases. Partitioning of the dataset should aim to identify which objects are accessed by which of these processes. Transactional analysis should analyse the transactional requirements of each use-case‚ and the objects that are accessed in each transaction. Object interaction diagrams are useful in this respect. The OO design phase should include the design of optimal access and index structures to support the navigation

Objective: The student is able to use object diagrams to communicate ideas in familiar domains. Initial script for introducing object diagrams: Here we have an object diagram that represents a situation in some particular school. The actual school is much larger; we are only representing a subset of all the situations‚ and there are many more types of links and many more types of objects that might be used. An object diagram can be paraphrased in a natural language. Here is a description that

The Three Tenets of Object-Oriented Programming Languages According to Bjarne Stroustrup‚ author of the C++ programming language‚ for a language to call itself object-oriented‚ it must support three concepts: objects‚ classes‚ and inheritance. However‚ object-oriented languages have come to be more commonly thought of as those languages built on the tripod of encapsulation‚ inheritance‚ and polymorphism. The reason for this shift in philosophy is that over the years we’ve come to realize that encapsulation
