super这东西我还不太懂 

 1 abstract class Report {
 2     void runReport() {
 3         System.out.println("设置报告");
 4     }
 5     
 6     void printReport(){
 7         System.out.println("输出报告");
 8     }
 9 }
10 
11 public class BuzzwordsReport extends Report {
12     void runReport() {
13         //在这里写代码
14         super.runReport();//调用父类的同时覆盖了父类，super
15         System.out.println("子类输出报告");
16     }
17     
18     public static void main(String[] args) {
19         BuzzwordsReport br = new BuzzwordsReport();
20         br.runReport();
21     }
22 }
