need to provide the code for the destructor, but instead the default destructor performs the operation automatically. However, if you need to do some important things before you delete an object instance, you should provide a specific destructor.For example, if a variable is out of range, the code cannot access it, but the variable still exists somewhere in the computer's memory. Only in. NET runtime to perform its garbage collection, the instance is

, all non-static constructors are also referred to as instance constructors.　2. Static ClassWe often want the class to contain only static members, and cannot be used to instantiate objects such as the console. A simple way to do this is to use a static class instead of setting the class's constructor to private. A static class can contain only static members and does not require an instance constructor because, by definition, it cannot be instantiated at all. However, a static class can have a

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

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
