Java program to print X star pattern program – We have written the below print/draw X asterisk/star pattern program in four different ways with sample example and output, check it out. At the end of the program, we have added compiler so that you can execute the below codes. ...
The abstract factory pattern is similar to the factory pattern and is a factory of factories. If you are familiar with the factory design pattern in Java, you will notice that we have a single factory class that returns the different subclasses based on the input provided and the factory clas...

JAVA设计模式(DESIGN PATTERNS IN JAVA)读书摘要 第1部分接口型模式——第3章 适配器(Adapter)模式 客户端代码提供接口来写具体实现类时,要利用已经实现接口功能的现有类,但是接口的方法名和现有类的方法名不一致,则需要使用适配器模式。 接口适配 如图所示,...
JAVA设计模式(DESIGN PATTERNS IN JAVA)读书摘要 第1部分接口型模式——第4章 外观(Facade)模式 外观模式就类似于一个工具包,一个类对应一个功能。 外观模式的意图是为子系统提供一个接口,便于它的使用。 书中给出的例子是画一个哑弹的飞行路径, 初始的类的设计是这样的,看下图,...
