Java字串轉日期範例
1.//欲轉換的日期字串2.String dateString = "20010-03-02 20:25:58";3.//設定日期格式4.SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");5.//進行轉換6.Date date = sdf.parse(dateString);7.System.out.println(date);
以上不支援 gwt, 若要在 gwt 字串日期互轉, 必須使用
DateTimeFormat
原因為：
GWT Doesnt support this java APi. It's explicit in documentation pages
GWT does not provide full emulation for the date and number formatting
classes (java.text.DateFormat, java.text.DecimalFormat,
java.text.NumberFormat, java.TimeFormat, et cetera). Instead, a subset
of the functionality of the JRE classes is provided by
com.google.gwt.i18n.client.NumberFormat and
com.google.gwt.i18n.client.DateTimeFormat
GWT provides the DateTimeFormat class to replace the functionality of
the DateFormat and TimeFormat classes from the JRE.
