This idea is exactly the same as what we often use. MyCollection defines some operations of the collection, MyIterator defines a series of iterative operations, and holds Collection instances. Let's look at the implementation code:The Liskov Substitution Principle (LSP) is one of the basic principles of object-oriented design. The Richter substitution principle says that wherever a base class can appear, subclasses can certainly appear. LSP is the cornerstone of inheritance reuse. Only when derivative classes can replace base classes and the functions of software units are not affected can base classes be truly reused, and derivative classes can also add new behaviors to base classes. The Richter substitution principle is a supplement to the "open-close" principle. The key step to realize the "open-close" principle is abstraction. The inheritance relationship between the base class and the subclass is the concrete realization of abstraction, so the Richter substitution principle is the specification of the concrete steps to realize abstraction. --From BaiduMore slowlyUnderstanding Enhanced Module PatternsSo this ford's second attack is随即想起了震天的喊杀声，众人不禁一惊，苏岸正是大感惊愕，长剑已经出鞘一般。……不知过了多久，杨长帆逐渐恢复了神智，想努力睁眼，却使不上劲，这让杨长帆陷入了剧烈的胆寒心惊——自己应该是死了，却还有神智，这就说明现在自己是一个灵魂，如果灵魂存在的话，身为唯物主义者，恐怕马上要面临不尊重各路大神的报应了。
