UML中的关联关系

UML中的关联关系其内在意思就是has a 如图: 

相对于依赖关系,关联关系在代码中有所体现.上图中的关联关系在代码中体现为

     

其中water 中将Climate作为其中的属性. 
当然,关联关系中也有双相关联,如图:

 

关联又分为组合,聚合

对应的代码如下: 
 

设计模式中的关联关系 

代码如下:

  1: //工作经历

  2:     class WorkExperience

  3:     {

  4:         private string workDate;

  5:         public string WorkDate

  6:         {

  7:             get { return workDate; }

  8:             set { workDate = value; }

  9:

 10:         }

 11:

 12:         private string company;

 13:         public string Company

 14:         {

 15:             get { return workDate; }

 16:             set { workDate = value; }

 17:         }

 18:     }

 19:

 20:     //简历

 21:     class Resume : ICloneable

 22:     {

 23:         private string name;

 24:         private string sex;

 25:         private string age;

 26:

 27:         private WorkExperience work;//组合关系,简历必须有工作经历

 28:

 29:         public Resume(string name)

 30:         {

 31:             this.name = name;

 32:             work = new WorkExperience();

 33:         }

 34:

 35:         //设置个人信息

 36:         public void SetPersonInfo(string sex, string age)

 37:         {

 38:             this.age = age;

 39:             this.sex = sex;

 40:         }

 41:

 42:         //设置个人经历

 43:         public void SetWorkExperience(string workDate, string company)

 44:         {

 45:             work.WorkDate = workDate;

 46:             work.Company = company;

 47:         }

 48:         //显示

 49:         public void Display()

 50:         {

 51:             Console.WriteLine("个人信息");

 52:

 53:         }

 54:         public object clone()

 55:         {

 56:             return (Object)this.MemberwiseClone();

 57:

 58:         }

 59:     }
