Calendar

Calendar cl= Calendar.getlnstance();ll创建日历类对象/l比较简单，自由System.out.printIn(c);
l2.获取日历对象的某个日历字段
System.out.printIn("年:"+c.get(Calendar.YEAR));
System.out.println(“月:"+(c.get(Calendar.MONTH)+1));
System.out.println(“日:"+c.get(Calendar.DAY_OF_MONTH));System.out.println("小时:"+c.get(Calendar.HOUR));
System.out.println("分钟:"+c.get(Calendar.MINUTE));System.out.println(“秒:"+c.get(Calendar.SECOND));
lCalender没有专门的格式化方法，所以需要程序员自己来组合显示System.out.printIn(c.get(Calendar.YEAR)+"年"+(c.get(Calendar.MONTH)+1)+"月"+c.get(Calendar.DAY_OF_MONTH)+"日");
