java List排序简单处理

List<DataViewBean> tempList=new ArrayList<DataViewBean>();
		tempList=factoryServ.getDataViewBySumId(sumId, scheme, et);
		
		//排序 降序
		Collections.sort(tempList,new Comparator<DataViewBean>(){   
			            public int compare(DataViewBean arg0, DataViewBean arg1) {   
			                return arg1.getThisEn().compareTo(arg0.getThisEn());   
			            }   
			        });  

List<DataViewBean> tempList=new ArrayList<DataViewBean>();
		tempList=factoryServ.getDataViewBySumId(sumId, scheme, et);
		
		//排序 升序
		Collections.sort(tempList,new Comparator<DataViewBean>(){   
			            public int compare(DataViewBean arg0, DataViewBean arg1) {   
			                return arg1.getThisEn().compareTo(arg0.getThisEn());   
			            }   
			        });
