装饰模式实例复杂的奖金计算

复杂的奖金计算

奖金分类，对于个人有当月奖金、个人累计奖金、个人业务增长奖金、及时回款奖金、限时成交加码奖金等；对于业务主管或者是业务经理，除了个人奖金外，还有团队累积奖金、团队业务增长奖金、团队盈利奖金等。

计算公式也有不同

计算奖金金额的基数也有不同

奖金的计算方式会经常变化。要适于调整和修改

成员接口

package A;
 
public abstract class Component {
 
public abstract double pay();
 
}

人，两个属性在，职务和姓名

package A;
 
public class Person extends Component {
 
  private String name;
  private String position;
  
  public Person() {
  }
 
  public Person(String name, String position) {
    
    this.name = name;
    this.position = position;
  }
   
  public double pay() {
    System.out.print(position+name+"累计奖金为");
    return 0;
  }
 
}

奖金的装饰类

package A;
 
public class Wage extends Component {
 
  protected Component component;
  public void Decorator(Component component)
  {this.component=component;
 
}
  public double pay()
  {if(component!=null)
    return component.pay();
  else
    return 0;
  }
}

当月奖金，一个属性，奖金数额

package A;
 
public class Month extends Wage {
private double money;
 
public Month() {
  
}
 
public Month(double money) {
  
  this.money = money;
}
 
public double pay()//月奖金
{System.out.print("月奖金 "+money+"元 ");
  return super.pay()+money;
}
}

业务增长奖金，一个 属性，业务增长额，计算公式为业务增长额乘0.2

package A;
 
public class Increase extends Wage{
  private double yewue;
  
  public Increase() {
  
  }
 
  public Increase(double yewue) {
  
    this.yewue = yewue;
  }
 
  public double pay()
  {System.out.print("个人业务增长奖金 "+yewue*0.2+"元 ");
  return super.pay()+yewue*0.2;
  }
}

团队奖金一个属性，奖金额

package A;
 
public class Team extends Wage {
  private double money;
  
public Team() {
    
  }
 
public Team(double money) {
  
    this.money = money;
  }
 
public double pay()
{System.out.print("团队增长奖金"+money+"元 ");
return super.pay()+money;
}
}

团队增长奖金，一个属性，增长值，公式为增长值乘0.5

package A;
 
public class TeamIncrease extends Wage {
  private double zengzhang;
  
public TeamIncrease() {
    
  }
 
public TeamIncrease(double zengzhang) {
    
    this.zengzhang = zengzhang;
  }
 
public double pay()
{System.out.print("团队增长奖金"+zengzhang*0.5+"元 ");
return super.pay()+zengzhang*0.5;
}
}

测试

package A;
 
public class Test {
public static void main(String args[])
{Person xc=new Person("小李","程序员");
Person xd=new Person("老王","团队经理");
Month mo=new Month(3000);
Increase in=new Increase(1500);
mo.Decorator(xc);
in.Decorator(mo);
Team tm=new Team(5000);
TeamIncrease ti=new TeamIncrease(2000);
tm.Decorator(xd);
ti.Decorator(tm);
System.out.println(in.pay()+"元");
System.out.println(ti.pay()+"元");
}
}
