Is there any way in java(java.util.* or Joda api ) to convert "2020-04-03 20:17:46" to "yyyy-MM-dd'T'HH:mm:ss"
new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss")
.parse("2020-04-03 20:17:46")
its giving java.text.parseException always
Just for the case you are using Java 8 or above, make use of java.time.
See this simple example:
public static void main(String[] args) {
// example datetime
String datetime = "2020-04-03 20:17:46";
// create a formatter that parses datetimes of this pattern
DateTimeFormatter parserDtf = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
// then parse the datetime with that formatter
LocalDateTime ldt = LocalDateTime.parse(datetime, parserDtf);
// in order to output the parsed datetime, use the default formatter (implicitly)
System.out.println(ldt);
// or format it in a totally different way
System.out.println(ldt.format(
DateTimeFormatter.ofPattern("EEE, dd. 'of' MMM 'at' hh-mm-ss a",
Locale.ENGLISH)
)
);
}
This outputs
2020-04-03T20:17:46

Please note that this doesn't consider any time zone or offset, it just represents a date and time consisting of the passed or parsed years, months, days, hours, minutes and seconds, nothing else.
