java代码中，我要得到一个 String s= 当前时间值，
我要在System.out.println(s)时，可输出 (如 2012-02-21 80:00:00) 这样的值
这怎么实现呀，thanks

楼主，这个你取到系统当前时间值，然后装换成字符串啊 很简单的。自己解决吧，会提升自己的能力的。

- Java code
public static String GetTimeByString() { Calendar c = Calendar.getInstance(); int second; int minute; int hour; int day; int month; int year; year = c.get(Calendar.YEAR); month = c.get(Calendar.MONTH); day = c.get(Calendar.DAY_OF_MONTH); hour = c.get(Calendar.HOUR_OF_DAY); minute = c.get(Calendar.MINUTE); second = c.get(Calendar.SECOND); String syear = String.valueOf(year); String smonth; String sday; String shour; String sminute; String ssecond; if(month < 10) smonth = "0" + month; else smonth = String.valueOf(month); if(day < 10) sday = "0" + day; else sday = String.valueOf(day); if(hour < 10) shour = "0" + hour; else shour = String.valueOf(hour); if(minute < 10) sminute = "0" + minute; else sminute = String.valueOf(minute); if(second < 10) ssecond = "0" + second; else ssecond = String.valueOf(second); String time = syear + "-" + smonth + "-" + sday + " " + shour + ":" + sminute + ":" + ssecond; return time; }

- Java code
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String time=df.format(new Date()); System.out.println("当前的时间为："+time);
