如何在 Java 中使用 SimpleDateFormat 获取正确的书写日期

Question

I have this:

DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
Date result = dateFormat.parse(this.getCreatedTime());

Basically I want to convert a string like "2016-09-27T09:19:57Z" into something like "September 27, 2016 at 9:19 AM".

If I use the code above I end up with a Date object, but all the methods are deprecated. So how do I achieve this?

Answer 1

You can use DateFormat again as @Thomas wrote:

DateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
Date inputDate = inputFormat.parse(this.getCreatedTime());
DateFormat outputFormat = new SimpleDateFormat("outputFormat");
String output = outputFormat.format(inputDate);

Answer 2

You should do research before posting any question here.

Use this to get Date from your required pattern

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.getDefault());
Date date = null;
try {
    date = format.parse(unformattedDate);
} catch (ParseException e) {
    e.printStackTrace();
}

Make new instance of your desired patter.

format = new SimpleDateFormat("MMMM dd, yyyy 'at' HH:mm a", Locale.getDefault());
String formattedDate = format.format(date);
