Java and Locale based formatting

Folks working on localization, often ends up in situations they need to see a list of what the Locale specific information looks like in Java. They need a sample of each locale and not just a simple list of supported locales.

Here's a simple implementation (+/-) thrown together after googling the basics of the Java API, that renders a table which has samples of localized in each and every locale supported by Java.

import java.io.FileNotFoundException;
import java.io.PrintWriter;
import java.io.UnsupportedEncodingException;
import java.text.DateFormat;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Currency;
import java.util.Date;
import java.util.Locale;

public class CurrencyFormatterExample {
  
    private static PrintWriter pw;

    public static void format(Locale currentLocale) {
    Double price = new Double(1234.56);
    NumberFormat currencyFormatter;
    DateFormat df = DateFormat.getDateTimeInstance(DateFormat.LONG,
        DateFormat.MEDIUM, currentLocale);
    String currencyOut;
    currencyFormatter = NumberFormat.getCurrencyInstance(currentLocale);
    currencyOut = currencyFormatter.format(price);
    Currency currency = currencyFormatter.getCurrency();
    String dateFormat = df.format(new Date());
        pw.print("<tr><td>" + currentLocale.toString() + "</td>" +
                 "<td>" + currencyOut + "</td>" +
                 "<td>" + currency.getCurrencyCode() + "</td>" +
                 "<td>" + currency.getSymbol(currentLocale) + "</td>" +
                 "<td>" + unicodeEscape(currency.getSymbol(currentLocale)) + "</td>" +
                 "<td>" + dateFormat + "</td></tr>");
        System.out.println(currentLocale.toString() + "\t\t" + currencyOut + "\t\t" + dateFormat);
    }

    public static void main(String args[]) throws UnsupportedEncodingException {
    try {
        pw = new PrintWriter("format.html", "UTF-8");
        pw.print("<html><head><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" /></head>");
        pw.print("<body><table>");
        pw.print("<tr><th>LOCALE</th>" +
                     "<th>FORMATTED PRICE</th>" +
                     "<th>CURRENCY CODE</th>" +
                     "<th>CURRENCY SYMBOL</th>" +
                     "<th>UNICODE ESCAPED CURRENCY SYMBOL</th>" +
                     "<th>FORMATTED DATE</th></tr>");
        Locale[] locales = Locale.getAvailableLocales();
        for (int i = 0; i < locales.length; i++) {
        CurrencyFormatterExample.format(locales[i]);
        }
        pw.print("</table></body></html?");
        pw.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    }

    private static final char[] hexChar = {
        '0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F'
    };

    private static String unicodeEscape(String s) {
    StringBuilder sb = new StringBuilder();
    for (int i = 0; i < s.length(); i++) {
        char c = s.charAt(i);
        if ((c >> 7) > 0) {
        sb.append("\\u");
        sb.append(hexChar[(c >> 12) & 0xF]);
        sb.append(hexChar[(c >> 8) & 0xF]);
        sb.append(hexChar[(c >> 4) & 0xF]);
        sb.append(hexChar[c & 0xF]);
        }
        else {
        sb.append(c);
        }
    }
    return sb.toString();
    }

}

Often with such code, the printout on the java console in eclipse works fine but the populated dates, numbers and currencies in different languages, cannot be seen in the browser. I ripped of the Unicode escaping code after some googling to fix this issue. I don’t know how great the algorithm is but it does the job as far as I can tell.

Another unique feature of the generated table is that XXX is thrown in as a placeholder where ever the row represents a language and not a region so it does not have a currency associated with it.
