软件工程设计原理接口隔离原则，具体实现及JAVA代码举例

接口隔离原则（Interface Segregation Principle, ISP）是面向对象设计原则之一，旨在减少不必要的依赖关系，通过拆分庞大且臃肿的接口为更小、更具体的接口来实现。这个原则强调“客户端不应该被迫依赖于它不使用的接口”，意味着一个类不应该被迫实现它不使用的方法。具体实现接...

软件工程设计原理依赖倒置原则，具体实现及JAVA代码举例

在软件工程中，依赖倒置原则（Dependency Inversion Principle, DIP）是一项重要的设计原则，它是SOLID原则中的一个组成部分。这个原则主张高层模块不应该依赖于低层模块，而是应该依赖于抽象；抽象不应该依赖于细节，细节应该依赖于抽象。这种设计方法有助于降低代码间的耦合度，...

软件工程设计原理开放封闭原则，具体实现及JAVA代码举例

开放封闭原则（Open/Closed Principle, OCP）是面向对象设计的核心原则之一，它指出软件实体（类、模块、函数等）应该对扩展开放，对修改封闭。这意味着在不修改已有代码的前提下，可以通过扩展来增加新的功能，从而提高软件系统的灵活性和可维护性。具体实现实现开放封闭原则的关键是通过抽...

软件工程设计原理里氏替换原则，具体实现及JAVA代码举例

里氏替换原则（Liskov Substitution Principle, LSP）是面向对象设计的基本原则之一，由Barbara Liskov提出。这个原则指出，如果类 S 是类 T 的子类型，则程序中使用 T 的对象的地方都可以不经修改地使用 S 的对象。换句话说，子类的对象应该能够替换掉它们的...

哈希表原理与Java HashSet、LinkedHashSet实现

一、哈希表原理哈希表（Hash Table）是一种使用哈希函数组织数据的数据结构，它实现了从键（Key）到值（Value）的快速映射。在哈希表中，数据的存储位置是通过其键值经过哈希函数计算后得到的。哈希表的核心思想是使用哈希函数将键转化为数组的索引，从而在常数时间内进行数据的查找。哈希表的主要操...
