//对agreeList进行排序 Collections.sort(agreeList,new Comparator(){ public int compare(Object obj1, Object obj2) { Transition transition1 = (Transition)obj1; Transition transition2 = (Transition)obj2; return transition1.getName().compareTo(transition2.getName()); } });

利用对象的name值进行排序，用 compareTo 进行比较 如果是int型，直接用 int a - int b

//对agreeList进行排序 Collections.sort(agreeList,new Comparator(){ public int compare(Object obj1, Object obj2) { Transition transition1 = (Transition)obj1; Transition transition2 = (Transition)obj2; return transition1.getName().compareTo(transition2.getName()); } });

//对集合进行排序 从大到小 Collections.sort((List<SaBillInfoDto>)billCollection, new Comparator<SaBillInfoDto>() {

@Overridepublic int compare(SaBillInfoDto o1, SaBillInfoDto o2) {	// TODO Auto-generated method stub	if ((o1.getBillAmount() - o2.getBillAmount()) > 0) {			return -1 ;	}else {		return 1 ;	}	}});
