Collections.sort 排序

list 中排序分为降序和升序

private List<LookupEntry> lookupEntryDescSort(List<LookupEntry> list) {
		// TODO Auto-generated method stub
	 Collections.sort(list,new  Comparator<LookupEntry>() {
			@Override
			public int compare(LookupEntry o1, LookupEntry o2) {
				// TODO Auto-generated method stub
               
                                //降序
				return o2.getName().compareTo(o1.getName());
			}
		});
	 return list;
}
private List<LookupEntry> lookupEntryAscSort(List<LookupEntry> list) {
		// TODO Auto-generated method stub
	 Collections.sort(list,new  Comparator<LookupEntry>() {
			@Override
			public int compare(LookupEntry o1, LookupEntry o2) {
				// TODO Auto-generated method stub
               
                                //升序
				return o1.getName().compareTo(o2.getName());
			}
		});
	 return list;
}
