获取年月日时分秒

Calendar c = Calendar.getInstance();

int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH) + 1;
int date = c.get(Calendar.DATE);
int hour = c.get(Calendar.HOUR_OF_DAY);
int minute = c.get(Calendar.MINUTE);
int second = c.get(Calendar.SECOND);
int milliSecond = c.get(Calendar.MILLISECOND);

System.out.println("年：" + year);
System.out.println("月：" + month);
System.out.println("日：" + date);
System.out.println("时：" + hour);
System.out.println("分：" + minute);
System.out.println("秒：" + second);
System.out.println("毫秒：" + milliSecond);
