用个中间变量转换,不错的思想

public void setRecks(List tradeList,Vector<ReCheck> myreChecks,long begin ,long end){
			long start = begin;
			for(int i=0;i<tradeList.size();i++){
				Trade tradeLast = (Trade) tradeList.get(i);//之后一个交易
				if(tradeLast.getTradeNo()-start>1){
					ReCheck rck=new ReCheck();
					rck.setBegin(start);
					rck.setEnd(tradeLast.getTradeNo());
					myreChecks.add(rck);
				}
				start = tradeLast.getTradeNo();
			}
			if(end - start>1){
				ReCheck rck=new ReCheck();
				rck.setBegin(start);
				rck.setEnd(end);
				myreChecks.add(rck);
			}
		}
