Static types, dynamic types, and type derivationIn programming language classifications, C/c++c is often considered a static type of language. And some programming languages are called "dynamic types," such as Python. In general, the difference
C + + genericsC + + generics are different from the run-time polymorphic mechanism of virtual functions, the static polymorphism supported by generics, when the type information is available, the maximum efficiency and flexibility can be obtained by

Java generics-type eraseI. OverviewJava generics in the use of the process has many problems, such as the absence of List.class, list can not be assigned to list (non-covariant), Strange classcastexception and so on. Proper use of Java generics
bug patterns are recurring correlations between bugs that have occurred in a program and potential bugs. With this knowledge of patterns and bug phenomena, programmers can quickly identify new bugs and prevent them from happening. the bug pattern is
: Network Disk DownloadContent Introduction· · · · · ·This book provides a comprehensive overview of the new features of the milestone version of Java 8, including lambdas, streaming, and functional programming. With functional programming features,
The JVM executes objects that are very familiar with class files, we are also known as class files, and the JVM specification defines this compiled code file (although not the actual file as mandatory) is very detailed, but we only talk about some
Is enough to show how important an interface is in an object-oriented domain. But JS does not have built-in interface mechanisms like other object-oriented high-level languages (c#,java,c++, etc.) to determine that a group of objects and another

const_cast (expression)The operator is used to modify the const or volatile properties of a type. In addition to const or volatile adornments, the type_id and expression types are the same.A constant pointer is converted into a very good pointer,
Interface is the key to achieve the pluggable nature of components, the key to pluggable components is the existence of a common interface, and each component implements this interface.
What is an interface?
Interfaces in Java are
C-style Cast Example:int i;Double D;i = (int) d;The code above is the D of the type double, which is converted to an integer value by (int) d and assigned to the shape variable i (note that the value of D itself has not changed). This is the typical
C # frequently encounters type conversions and struct conversions when referring to DLL references for C + +
1. C + + in the char type is 1 bytes, C # char is two bytes, can not be used; You can use the byte correspondence in C #
2. Structtype
The virtual machine loads the description class data from the class file into the memory, verifies the data, transforms and initializes it, and eventually forms a Java type that can be used directly by the virtual machine, which is the class loading
I. Understanding Typescript
Typescript is a set of programming languages developed by Microsoft, which is referred to as JavaScript superset, and people who have seen some TS code may obviously be aware of its difference from JS, such as TS added

C + + type conversions are divided into: implicit type conversions and explicit type conversions1th part. Implicit-type conversionsAlso known as
