Generally speaking feel can accept, the teacher said the book content can understand understand, class homework These can also be completed independently, although do when still a little rusty but fortunately can find a way to solve in time. In the future study must keep in mind the teacher's teaching more thinking more practice, independent completion of homew

. NET technology is vast, and no book can be used up, because as a mainstream development platform, it covers too much content. However, when I read Mr. Jin xuliang's book (basic article + application Article), I began to doubt my argument. Yes, this book is still not exhaustive. net. However, it may be incomparable in terms of technical breadth and depth. In oth

expressions: A. Example: SomeDelegateType del2 = arguments =>{ return arguments. ToString ();}; B. Lambda expressions are actually further simplified by the anonymous method. They can be used to define an anonymous function and pass it to a delegate variable. C. Usage: C.1 when there is only one input parameter, parentheses are optional. If there is only one return statement in an expression, the return keyword can be omitted. Func Func C.2 when two or more input parameters are separated by c

Chapter8_math instance, the Add method, which is declared as PUBILC in the parent class, is clearly overridden in the subclass.Of course, when we were wondering about "Case 3", we might have overlooked that "case 3" was created as a math instance, so from the compilation to the heap is a typical parent class, so this is not the overriding operation at all.Now, there is a key point to the static method problem of the static modification,The sub method, which is now declared static, is obviously

the reference type variable is allocated in the managed heap. 2. Reference The Memory Model of the Type Variable A. the reference type variable exists in the thread stack, and the referenced object exists in the managed heap. There are four types of reference: class type, interface type, array type, and delegate type. B. [case notes in the book]Objs = new MyClass [10] indicates that 10 reference type varia

Chapter 4 event and event-driven 【Abstract】 event-driven is an important feature of object-oriented software systems. This chapter describes the.

Chapter 4 exception capture and handling [Summary] exception handling is a problem that must be carefully considered when developing software products. It directly determines the robustness of software products in a large program. This chapter mainly introduces the. NET exception handling infrastructure and some suggestions for exception handling. Section 1. NET Exception Handling Basics 1. Exception Overview: A. Definition: errors caused by running the program. Exceptions are not the same as bu

according to the part, and each part is assigned to the designated person to do it;The end is to assemble all the finished parts, which is a bicycle;In this way, the bicycle, maintainability and extensibility are stronger than the process-oriented thinking;The only drawback is that the upfront investment time is a little longer;Java object-

In the object-oriented programming of PHP, you will always encounter Class test{public static function test () { self::func (); Static::func (); } public static function Func () {}} But do you know the difference between self and static? In fact, the difference is very simple, just need to write a few demo can understand: Demo for self: Class car{public sta

A program consists of two parts: a function of data and operation data; The process-oriented design approach is the Top-down function decomposition, Decompose a requirement into multiple subfeatures, develop subfeatures and unit tests, and assemble them into a complete application; Problem: 1. The program focuses on functions, followed by data, and data flows from one function to another function; 2. Data structure needs to run through multiple f

existing classes to generate new classes;In layman's terms, the process of creating a new class (subclass or derived class) from an existing class (that is, a parent class or base class);In real life, inheritance can achieve the purpose of property reuse, while in Java, inheritance can make code reusable. Polymorphicpolymorphism means that the same function has different implementations in different classes.The advantage of polymorphism is that it m

Different from C ++, Java is a pure object-oriented language. Object-oriented has three main features: inheritance, encapsulation, and polymorpism ). This part contains a lot of content. 01 I will take an example to familiarize myself with the
