Course Introduction:Golang is a statically typed programming language. One of its unique features is the reduction of program runtime errors through static type checking. Static type checking refers to checking the code for type errors at compile time, rather than finding errors at run time. In this way, the occurrence of program crashes, exceptions, and other runtime errors can be greatly reduced. Golang's static type checking mechanism is mainly reflected in the following aspects. First of all, Golang requires that the type of the variable must be specified when declaring the variable. This means that when writing code

Course Introduction:Java reflection is a mechanism that allows a program to inspect and modify the structure and behavior of objects at runtime. This means that the program can obtain the object's class name, field name, and method name at runtime, as well as call any method of the object. This makes reflection an extremely useful tool for a wide variety of purposes, including runtime type checking, dynamic programming, debugging, and testing. One of the most common uses of reflection is runtime type checking. This refers to a program checking the type of an object at runtime in order to decide what to do with the object. For example, a program can use reflection to check whether an object is an instance of a certain type, or to obtain the class name of an object. This is useful for dynamic programming, as the program can make different decisions at runtime depending on the type of object. reflection

Course Introduction:Reflection objects are used to obtain type information at runtime. Classes that allow access to a running program's metadata are located in the System.Reflection namespace. Below is an application of Reflections - which allows viewing property information at runtime. It allows inspecting various types in an assembly and instantiating these types. It allows late binding to methods and properties. It allows creating new types at runtime and then using these types to perform some task. ul>Let's see an example - example usingSystem;[AttributeUsage(AttributeTargets.All)]publicclassHelpAttribute:Sys

Course Introduction:C++ parameter type safety checking ensures that functions only accept values of expected types through compile-time checks, run-time checks, and static assertions, preventing unexpected behavior and program crashes: Compile-time type checking: The compiler checks type compatibility. Runtime type checking: Use dynamic_cast to check type compatibility, and throw an exception if there is no match. Static assertion: Assert type conditions at compile time.
