String转换为Joda-time

DateTimeFormatter format = DateTimeFormat .forPattern("yyyy-MM-dd HH:mm:ss");    //时间解析  DateTime dateTime = DateTime.parse("2012-12-21 23:22:45", format);

Date转换为Joda-time

Date-->joda-time

Date date = new Date();  DateTime dateTime = new DateTime(date);

Calendar-->Joda-time

Calendar calendar = Calendar.getInstance();  dateTime = new DateTime(calendar);

String转换为Date(jdk)

 SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date  date = format.parse(str);

Joda-time转换为Date

Joda-time-->Date

Date date = new Date();  DateTime dateTime = new DateTime(date);                       // 计算完转换成jdk 对象  Date date2 = dateTime.toDate();

Joda-time-->Calendar

Calendar calendar = Calendar.getInstance();  dateTime = new DateTime(calendar);  //计算完转换为Calendar对象Calendar calendar2 = dateTime.toCalendar(Locale.CHINA);

Date\Joda-time输出为格式化字符串

Joda-time-->String

//时间格式化，输出==> 2012/12/21 23:22:45 Fri  String string_u = dateTime.toString("yyyy/MM/dd HH:mm:ss EE");

//格式化带Locale，输出==> 2012年12月21日 23:22:45 星期五  String string_c = dateTime.toString("yyyy年MM月dd日 HH:mm:ss EE",Locale.CHINESE);

Date-->String

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String str = format.format(date);
