这段声明to和cont方法是什么方法？为什么要声明？前面为什么还要各跟一个Destination和Contents？请教各位高手，谢谢

to() and cont() are methods no difference from other methods of the P class.

PS: consider to give your classes and methods meaningful names will help others to understand code.

Destination and Contents are inner classes of P class. (as your title has already suggested). Some attentions need to be noted when using inner classes.
- Inner classes are members of the class who contains them. So you should just treat them as members.
- Inner classes have visibility control like other members. (you can declare inner classes as private, public and even static)
- The compiled inner class will have the following name: xxx$yyy (where xxx is the "base" class, and yyy is the inner class)
- Invoke the inner classes the same way as invoke a method or a field.

When I was a kid I used to pray every night for a new bike. Then I realized that The Lord doesn't work that way, so I stole one and asked him to forgive me.
