Java interview 30 Question 1: What are the differences between final, finally, and finalize.Second, can anonymous inner class (anonymous internal class) be extends (inherited) other classes, or implements (implemented) interface (Interface )?Third,
First, the extraction class (abstract)In our actual development process, some classes do not need to be instantiated, such as some of the previous learning of the parent class, mainly for the subclass to inherit, so as to improve code
Php object-oriented? Interface Php object-oriented? Interface
Interface: interface
In php, we can specify which public external operations an object should have and use interfaces to specify.
The common method is the interface.
Learning content: Pumping like class, interface, final, class constants
First, the extraction class (abstract)
In our actual development process, some classes do not need to be instantiated, such as some of the previous learning of the parent
PolymorphicIf you want to describe the polymorphism briefly, I personally understand that: through inheritance, the parent class defines the method, the implementation of the Hugh is done by the subclass. 01 Code //Parent Class classPerson {
This article mainly introduces the predefined 6 kinds of interfaces in PHP, and explains Traversable, Iterator, Iteratoraggregate, Arrayaccess, Serializable and Closure in detail. We hope to help you.

When writing a program, I often get tangled up, whether an abstract object should be defined as an abstract class or an interface (Interface)? The two are very similar, even can be replaced with each other, difficult to choose. This question has

PHP predefined 6 interfaces are described below:
1.Traversable Traversal Interface
Oh! In fact, it is not an interface that can be used in PHP, internal classes can be used, it has a purpose is to detect whether a class can be traversed.
