Course Introduction：Detailed explanation of Java inheritance mechanism: the cornerstone of building object-oriented programs The inheritance mechanism in Java allows an object to inherit all properties and behaviors of its parent object, and is the core concept of object-oriented programming (OOPs). Through inheritance, we can create a new class based on an existing class, reuse the methods and fields of the parent class, and add new methods and fields on this basis. What is inheritance? The Java inheritance mechanism allows one class (subclass or derived class) to inherit the properties and methods of another class (superclass or parent class). Subclasses can access members (fields and methods) of the superclass, enforcing reuse rules, and promoting class hierarchy. Inheritance embodies the "IS-A" relationship, also known as the parent-child relationship. Why use Java inheritance?

Course Introduction：Key Points PHP's array interface allows programmers to simulate the characteristics of native data types in custom classes, similar to Python's methods. This enables custom classes to work like arrays and allows common array operations such as counting elements, looping through elements, and accessing elements through indexes. An interface is like a contract for a class, specifying the methods that a class must contain. They allow encapsulation of implementation details and provide syntax sugar, thereby improving the readability and maintainability of the code. PHP provides a library of predefined interfaces that can implement these interfaces to make objects similar to arrays. Countable, ArrayAccess and Iterator interfaces in PHP allow objects to pass cou respectively

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
