对集合中的对象进行排序，用collections.sort 到方法

//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()); } });ide

利用对象的name值进行排序，用 compareTo 进行比较 若是是int型，直接用 int a - int bcode

//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()); } });对象

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

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