Similarly, in December 28, 2000 Pub Date : object-oriented programming, you may want to model an abstract concept without being able to create an instance of it For example, the Number class represents the abstract concept of ISBN : 0-201-70393-9 numbers It makes sense to model numbers in a program, but it doesn't make sense to reate a Pages : 592 generic number object Instead, the Number class makes sense only as a superclass to such classes as Integer and Float, both of which implement specific kinds of numbers A class such as Number, which represents an abstract concept and should not be instantiated, is called an abstract class An abstract class can only be subclassed; it cannot be instantiated "This book stands above the rest because it has been available on the web and read by thousands of Java programmers class is an have received an the keyword abstract before the class sections To declare that yourThe authorsabstract class, useenormous amount of feedback about whichkeyword are good and which sections are confusing; the confusing ones have been improved I doubt that any in your class declaration: other Java book has undergone such trial by fire" -Metroplex Java User Group, wwwjavamugorg/reviews/. itextsharp read pdf line by line c#: PDFBox Quick Guide - Tutorialspoint c# pdfsharp get text from pdf Read table array from PDF file , itextsharp - CodeProject

Support for Parameter Covariance and Contravariance in Arrays Unfortunately, ever since C# 10, arrays allowed for covariance and contravariance For example, both PdaItem[] pdaItems = new Contact[] { } and Contact[] contacts = (Contact[])new PdaItem[] { } are valid assignments in spite of the negative implications discussed earlier The result is that the covariant and contravariant restrictions imposed by the compiler in C# 20 and the loosening of those restrictions in C# 40 to enable valid scenarios do ot apply to arrays As regrettable as this is, the situation can be avoided As 14 describes, a host of interfaces and collections are available that effectively supersede arrays and enable a super set of functionality Support for generics in combination with C# 30.Using Barcode drawer for Visual Studio .NET Control to generate, create barcode image in S .NET applications.Related: EAN-8 Printing .NET , Make UPC-E .NET , Creating ISBN .NET extract text from pdf file using itextsharp in c# Extract and verify text from PDF with C# | Automation Rhapsody

Related: . The Circle example class used above provides us with a clear picture of one of the most important features of object-oriented programming: no matter how the internal data of a class is organized and stored, it is the public interface that de nes how a user of the class (a programmer) will write code to interact with it We try to simplify the way objects are used by hiding all of the complex data mechanisms behind the class boundaries and exposing only those methods that manipulate objects of the class in such a way as to maintain an internal (and external) consistency To make a class truly robust, this consistency must be maintained throughout the entire period that an object is in use When we create a new object from a class using the New operator, it is important that from the word go, the object is in a valid state The default state of a new object is for every member variable to be null; ie numbers to have a zero value, strings to be empty, etc While this is acceptable for many classes of object, in some situations we need an object to be in a valid but non-null state from the instant it is created For example, if we have a Circle object, it is a null circle immediately after it has been created We could say that one essential feature of a circle is that it has a non-zero radius, since otherwise, it is really a point However, when we create a Circle object, we rst have to create a circle with a zero radius, and then update the radius If we are concerned about objects being used consistently, this poses a problem, since, for at least a short period of time, every Circle object has to go through an inconsistent state immediately after creation If a programmer who is unfamiliar with the class was to create a new circle and not set its radius to a non-zero value, this could cause problems Visual Basic and NET provide a way around this possible situation: the class constructor A constructor is a method whose purpose is to build an object in a valid state Recall that we use the New operator to create a new object of any class We can change the way that New works by creating a constructor method for a class This is a sub that sets up a new class member into a valid state, and is nvoked automatically at the point an object is created Currently, we create a new Circle object by using statements like:.
