//1.在UML中,【+】代表着public,【-】代表着prvite,【#】代表着protend
//2.如果A类继承了B类我们用【空心的三角形+实线】表示
//3.如果A类实现了接口，则我们用【空心的三角形+虚线】来表示
//4.如果我们在A类中需要"知道"另外的一个类时我们就用关联，关联的关系我们用【实线箭头】来表示
//5.聚合关系:表示一种弱的引用关系,体现的是A对象可以包含B对象,但B对象不是A对象的一部分(大雁-雁群)，他们的生命周期不一样【空心的菱形+实线箭头来表示】
//6.合成【组合】关系:是一种强的"拥有关系"，体现了严格的部分和整体的关系,整体和部分的生命周期一样。（鸟-翅膀）【实心的菱形+实线箭头】来表示。
