 PackageZhongqiuzuoye; Public classPeople1extendsmonkey{People1 (String s) {Super(s); //TODO Auto-generated constructor stub    }         Public voidspeak () {System.out.println ("Good for a small sample" It's going to talk! "); }     Public voidThink () {System.out.println ("Don't Talk! Think hard! "); }    }

 Package Zhongqiuzuoye;  Public class E1 {    publicstaticvoid  main (string[] args) {        // TODO Auto-generated method stubs New Monkey ("Tom");                          M.speak ();                 New People1 ("Xiaoming");        P.speak ();        P.think ();            }}
