Converting Date String To Another String

How can I convert from '2014-10-13T10:41:22.863+08:00' into '2014-10-13 10:41'? I have failed to do so: String date = '2014-10-13T10:41:22.863+8:00'; SimpleDateFormat dateFormat =

Solution 1:

Try this way,hope this will help you to solve your problem.

The Z at the end is usually the timezone offset. If you you don't need it maybe you can drop it on both sides.

SimpleDateFormatdf1=newSimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS");
SimpleDateFormatdf2=newSimpleDateFormat("yyyy-MM-dd HH:mm");
try{
    Dated= df1.parse("2014-10-13T10:41:22.863+8:00");
    System.out.println("new date format " + df2.format(d));
}catch(Exception e){
   e.printStackTrace();
}

Solution 2:

If you don't need to do some operation/manipulation on the Date before printing it in correct format, then you can just directly transform the string into yyyy-MM-dd HH:mm with this:

String date = "2014-10-13T10:41:22.863+8:00";

date = date.substring(0, 16);  // 2014-10-13T10:41, remove value after minutes
date = date.replace("T", " "); // 2014-10-1310:41, replace the 'T' character

System.out.println(date);      // 2014-10-1310:41

Else, if you want to parse it beforehand, then change the pattern to yyyy-MM-dd'T'HH:mm (note the additional of string constant 'T').

Stringdate="2014-10-13T10:41:22.863+8:00";

// parse the String to DateSimpleDateFormatsourceFormat=newSimpleDateFormat("yyyy-MM-dd'T'HH:mm");
DatedateTime=null;
try {
    dateTime = sourceFormat.parse(date);
} catch (ParseException e) {
    e.printStackTrace();
}
System.out.println(dateTime.toString()); // Mon Oct 13 10:41:00 SGT 2014// print the Date in expected formatSimpleDateFormattargetFormat=newSimpleDateFormat("yyyy-MM-dd HH:mm");
System.out.println(targetFormat.format(dateTime)); // 2014-10-13 10:41

The reason you got ParseException is because the format you use to parse (yyyy-MM-dd HH:mm) is not the same as the source (yyyy-MM-dd'T'HH:mm ...). Your SimpleDateFormatter expected whitespace instead of character 'T' after the date.
