How do you specify the date format used when JAXB marshals xsd:dateTime?

You can use an XmlAdapter to customize how a date type is written to XML. package com.example; import java.text.SimpleDateFormat; import java.util.Date; import javax.xml.bind.annotation.adapters.XmlAdapter; public class DateAdapter extends XmlAdapter<String, Date> { private final SimpleDateFormat dateFormat = new SimpleDateFormat(“yyyy-MM-dd HH:mm:ss”); @Override public String marshal(Date v) throws Exception { synchronized (dateFormat) { return dateFormat.format(v); } } @Override public … Read more

different result for yyyy-mm-dd and yyyy/mm/dd in javascript when passed to “new Date” [duplicate]

It boils down to how Date.parse() handles the ISO-8601 date format. The date time string may be in ISO 8601 format.

The UTC time zone is used to interpret arguments in ISO 8601 format that do not contain time zone … Read more

Add ‘decimal-mark’ thousands separators to a number

If you want to add a thousands separator, you can write: >>> ‘{0:,}’.format(1000000) ‘1,000,000’ But it only works in Python 2.7 and above. See format string syntax. In older versions, you can use locale.format(): >>> import locale >>> locale.setlocale(locale.LC_ALL, ”) ‘en_AU.utf8’ >>> locale.format(‘%d’, 1000000, 1) ‘1,000,000’ the added benefit of using locale.format() is that it … Read more

Format file size as MB, GB, etc [duplicate]

public static String readableFileSize(long size) { if(size <= 0) return “0”; final String[] units = new String[] { “B”, “kB”, “MB”, “GB”, “TB” }; int digitGroups = (int) (Math.log10(size)/Math.log10(1024)); return new DecimalFormat(“#,##0.#”).format(size/Math.pow(1024, digitGroups)) + ” ” + units[digitGroups]; } This will work up to 1000 TB…. and the program is short!
