Java - formarting number, dates, datetime, currency, locales and miscelaneous

We always get stuck when formarting number, dates, datetime, currency, locales and miscelaneous; so, a friend of mine, give us some snippets.

import java.text.DateFormat;
import java.text.DecimalFormat;
import java.text.NumberFormat;
import java.util.Date;
import java.util.Locale;

public class TestFormat {
    public static void main(String[] args) {

        // The "0" symbol shows a digit or 0 if no digit present 
        NumberFormat formatter = new DecimalFormat("000000"); 
        String s = formatter.format(-1234.567);  // -001235
        System.out.println(s);
        // notice that the number was rounded up 
         
        // The "#" symbol shows a digit or nothing if no digit present 
        formatter = new DecimalFormat("##"); 
        s = formatter.format(-1234.567);         // -1235
        System.out.println(s);
        s = formatter.format(0);                 // 0
        System.out.println(s);
        formatter = new DecimalFormat("##00"); 
        s = formatter.format(0);                 // 00
        System.out.println(s);
         
         
        // The "." symbol indicates the decimal point 
        formatter = new DecimalFormat(".00"); 
        s = formatter.format(-.567);             // -.57
        System.out.println(s);
        formatter = new DecimalFormat("0.00"); 
        s = formatter.format(-.567);             // -0.57
        System.out.println(s);
        formatter = new DecimalFormat("#.#");

        // The ";" symbol is used to specify an alternate pattern for negative values 
        formatter = new DecimalFormat("#;(#)"); 
        s = formatter.format(-1234.567);         // (1235)
        System.out.println(s);
