SimpleDateFormat类用于解析和格式化日期。要创建一个对象,首先导入以下包
import java.text.SimpleDateFormat;
设置日期
String strDate = "'Year = '"; strDate += "yyyy"; strDate += "'\nMonth = '"; strDate += "MMMMMMMMM"; strDate += "'\nHours = '"; strDate += "hh"; strDate += "a"; strDate += "'\nMinutes = '"; strDate += "mm"; strDate += "'\nSeconds = '"; strDate += "ss";
现在,创建一个对象并格式化日期-
SimpleDateFormat dateFormat = new SimpleDateFormat(strDate); String formattedDate = dateFormat.format(new Date());
以下是一个例子-
import java.text.SimpleDateFormat; import java.util.Date; public class Demo { public static void main(String args[]) { String strDate = "'Year = '"; strDate += "yyyy"; strDate += "'\nMonth = '"; strDate += "MMMMMMMMM"; strDate += "'\nHours = '"; strDate += "hh"; strDate += "a"; strDate += "'\nMinutes = '"; strDate += "mm"; strDate += "'\nSeconds = '"; strDate += "ss"; System.out.println("Date and Time...."); SimpleDateFormat dateFormat = new SimpleDateFormat(strDate); String formattedDate = dateFormat.format(new Date()); System.out.println(formattedDate); } }
输出结果
Date and Time.... Year = 2018 Month = November Hours = 09AM Minutes = 12 Seconds = 41
