Polymorphism separates the interface from the implementation by separating "what" and "How to do" from another perspective. The role of polymorphism is to eliminate the coupling between types, and polymorphic method invocations allow a type to

Programming | Repeating Java has a lot of praise of the function, the application of code is one of them. But if you want revolutionary change, you have to go far beyond the old code of "Replicator code, then change": combination (composition) and

This problem is more difficult to do, at first I think is a stack of solution, feel too cumbersome (out of the stack, into the stack, calculate volume), but it is not a good attempt, this method is still a little problem, after will think clearly.

Variables defined by final can be regarded as constants and cannot be changed;Methods defined by final cannot be overwritten;Classes defined by final cannot be inherited.Final Static is added with the static feature. Static and final are not

1 Final data:1> final modification before the basic type indicates that the modified variable is a constant and cannot be modified. A static or final field indicates that only a bucket cannot be changed.2> when final is used for object applications,
