java创建Timestamp的几种方式

java创建Timestamp的几种方式,目前总结了以下几种

  Timestamp time1 = new Timestamp(System.currentTimeMillis());
		
		Timestamp time2 = new Timestamp(new Date().getTime());
		
		Timestamp time3 = new Timestamp(Calendar.getInstance().getTimeInMillis());
		
		//不建议使用
		Timestamp time4 = new Timestamp(2011-1900,11,11,11,11,11,0);

如果不全，请提示我进行补充，非常感谢!
