java中使用匿名类重写

  public static void sortByGoodness(List<SimilarCluster> values) {
        Collections.sort(values, new Comparator<SimilarCluster>() {
            
            public int compare(SimilarCluster f1, SimilarCluster f2) {
                int result = 0;
                
                if( f1.getGoodness() < f2.getGoodness() ) {
                    result = 1; // order in the decreasing order of goodness value 
                }
                else if( f1.getGoodness() > f2.getGoodness() ) {
                    result = -1;
                }
                else {
                    result = 0;
                }
                return result;
            }
        });        
    }
