主要有两种方式,其中使用Date比较好控制,代码如下:
//使用Calendar
Calendar now = Calendar.getInstance();
System.out.println("年:" + now.get(Calendar.YEAR));
System.out.println("月:" + (now.get(Calendar.MONTH) + 1));
System.out.println("日:" + now.get(Calendar.DAY_OF_MONTH));
System.out.println("时:" + now.get(Calendar.HOUR_OF_DAY));
System.out.println("分:" + now.get(Calendar.MINUTE));
System.out.println("秒:" + now.get(Calendar.SECOND));
输出:
年:2018
月:5
日:4
时:22
分:48
秒:28
//使用Date
Date d = new Date();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println("当前时间:" + sdf.format(d));
输出:
当前时间:2018-05-04 22:48:28
