配料的基类（装饰者，用来对汉堡进行多层装饰，每层装饰增加一些配料，相当于上面Decorator）
package decorator;
public abstract class Condiment extends Humburger {

生菜（装饰者的第一层，相当于上面的decorator_zero）
package decorator;
public class Lettuce extends Condiment {
Humburger humburger;

this.humburger = humburger;

@Override
public String getName() {
return humburger.getName()+" 加生菜";
}
@Override
public double getPrice() {
return humburger.getPrice()+1.5;
}
}
辣椒（装饰者的第二层，相当于上面的decorator_first）
package decorator;
public class Chilli extends Condiment {
Humburger humburger;
public Chilli(Humburger humburger){
this.humburger = humburger;
}
@Override
public String getName() {
return humburger.getName()+" 加辣椒";
}
@Override
public double getPrice() {
return humburger.getPrice(); //辣椒是免费的哦
}
}
