今天听了一在线公开课,任务是作一个数字时钟,其中最关键的天然是获取当前的系统时间。作个简单的记录,以下:java
1. orm
Time time = new Time("GMT+8"); time.setToNow(); //Sets the time of the given Time object to the current time. 将事件获取对象置为当前时间
System.out.println(time.hour); System.out.println(time.minute); System.out.println(time.second);
2.对象
private SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss"); String str = sdf.format(new Date());
3.blog
Calendar calendar = Calendar.getInstance(); int hour = calendar.HOUR_OF_DAY; int minute = calendar.MINUTE; int second = calendar.SECOND;
