　　In "Think in Java" There is a sentence: Reuse code is one of Java's many compelling features. But to be a revolutionary language, it's not enough to just copy the code and change it, and it has to be able to do more. The most noticeable in this sentence is the "Reuse code", as much as possible to reuse the code that we programmers have been pursuing, and now I introduce a way to reuse code, is one of Java three major features---inheritance.　　Let's t
