求java Date类型字段加一天代码

[小小贾]

String startdate=UIDBComboBox1.getValue();
UIDBComboBox1为日期字段下拉框名称

[闲去野鹤]

new Date().getDay()+1;

[zuxianghuang]

public static Date getNextDay(Date date) { if (date == null) return null; Calendar calendar = Calendar.getInstance(); calendar.setTime(date); calendar.add(Calendar.DAY_OF_MONTH, 1); return calendar.getTime(); }

[安特矮油]

	public static void main(String[] args) throws Exception {
		String s = "2012-01-31";
		SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
		Date day = sdf.parse(s);
		Calendar c = Calendar.getInstance();
		c.setTime(day);
		c.add(Calendar.DATE, 1);
		System.out.println(sdf.format(c.getTime()));
	}

[减肥啊啊啊啊啊]

使用Calendar 类 对日期进行加减
