Converting UTC time in IST

Question

I have to convert 2017-10-12T09:48:28.338Z to IST ie dd-MM-yyyy HH:mm:ss . The code i used throws java.lang.IllegalArgumentException: Unknown pattern character 'Y'

Here is my code :

private String getStandardTime(String dateStr) {
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dddd'T'HH:mm:ss.SSSZ");
        df.setTimeZone(TimeZone.getTimeZone("UTC"));
        Date date = null;
        try {
            date = df.parse(dateStr);
        } catch (ParseException e) {
            e.printStackTrace();
        }
        df.setTimeZone(TimeZone.getDefault());
        String formattedDate = df.format(date);
        return formattedDate;
    }

Can anyone help me out here ? What i am doing wrong . for reference i checked

Try using the below line in your code:

 SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");

Z represent Timezone character, you have to quote it like 'Z'. Also you are using dddd instead of dd.
