好的，以下是对两个类的完整注释：

//Parcel1类
public class Parcel1 {
    //Contents类
    class Contents { //内部类
        private int i = 11;
        public int value() { 
            return i; 
        }     
    }
    //Destination类
    class Destination { //内部类
        private String label;
        Destination(String whereTo)  {   
            label = whereTo;    
        }         
        String readLabel() { 
            return label; 
        }      
    }
    //ship方法
    public void ship(String dest) {          
        Contents c = new Contents();
        Destination d = new Destination(dest);
        System.out.println(d.readLabel());
    }
    //main方法
    public static void main(String[] args)  {        
        Parcel1 p = new Parcel1();
        p.ship("Tanzania");
    } 
}

//Parcel2类
public class Parcel2 {
    //Contents类
    class Contents  {
        private int i = 11;
        public int value() { 
            return i; 
        }     
    }
    //Destination类
    class Destination {
        private String label;
        Destination(String whereTo) {  
            label = whereTo;  
        }         
        String readLabel() { 
            return label; 
        }      
    }
    //ship方法
    public void ship(String dest) {         
        Contents c = cont();
        Destination d = to(dest);                   
        System.out.println(d.readLabel());
    }
    //to方法，返回Destination对象
    public Destination to(String s) { 
        return new Destination(s);  
    }
    //cont方法，返回Contents对象
    public Contents cont() { 
        return new Contents();  
    } 
    //main方法
    public static void main(String[] args) { 
        Parcel2 p = new Parcel2();
        p.ship("Tanzania");
        Parcel2 q = new Parcel2();
        Parcel2.Contents c = q.cont();
        Parcel2.Destination d = q.to("Borneo");
    } 
}

希望这些注释能够对您有所帮助！
