在Java中将字符串日期转换为美国格式 [英] converting a string date into US format in java

问题描述

我有以下代码，其中日期以字符串类型出现，因此我必须将其设置为美国格式
，因此在下面已显示了它

I have the below code in which date come as string type and I have to set it in US format so below I have shown it

private static final SimpleDateFormat usOutputDate =  new SimpleDateFormat("MM/dd/yyyy");

，在一个方法中，我编写了以下代码，并在 dealDateString 的值是 2015年3月2日

and inside a method I have written the below code and inside dealDateString the value is coming as 02-Mar-2015

// dealDateString = 02-Mar-2015 
java.util.Date  dealDate = extractDate(dealDateString); 
//here its value get converted in US format that is 03/02/2015
String dd = usOutputDate.format(dealDate); 

DateFormat format = new SimpleDateFormat("MM/dd/yyyy", Locale.US); 
// ***issue comes here as it get back converted in US format ***
java.util.Date date =  format.parse(dd);
brokerInvoiceLineItem.setDealDate(new Date(date));

如上面的代码所示，它的值在 String dd 是 03/02/2015 ，但问题出在格式变量中，其中
的值转换为英国格式，我不希望这样做，请告知我如何将其转换为英国格式，因为它已经将
转换为以前存储在 String dd 中的美国格式。

as shown in the above code that's it value inside String dd is 03/02/2015 but the issue comes at format variable where its value get converted back in UK format which i do not want please advise how can i convert it in UK format as it is already converted in US format previously stored inside String dd.

推荐答案

尝试一下...

  try {
        //parsing date format
        SimpleDateFormat formatter = new SimpleDateFormat("dd-MMM-yyyy");

        String dealDateString = "02-Mar-2015";
        Date date = formatter.parse(dealDateString);
        TimeZone tz = TimeZone.getDefault();

        //converting date format for US
        SimpleDateFormat sdfAmerica = new SimpleDateFormat("MM/dd/yyyy");
        TimeZone tzInAmerica = TimeZone.getTimeZone("America/New_York");
        sdfAmerica.setTimeZone(tzInAmerica);

        String sDateInAmerica = sdfAmerica.format(date); // Convert to String first
        System.out.println("Date (String) : " + sDateInAmerica);

    } catch (Exception bug) {
        bug.printStackTrace();
    }
