Problem:

You want to use a currency other than the default for the region.

Solution:

We can specify a currency separate from a region.  This will give us a numeric format that is appropriate to the locale, but use a currency code for the specified locale.

//Get a locale.
Locale italian = new Locale("it","IT");
//Get a currency instance
Currency c = Currency.getInstance("JPY");
//Get a currency instance
NumberFormat nf = NumberFormat.getCurrencyInstance(italian);
nf.setCurrency(c);
//format and output.  Notice the rounding is not limited to two place on the output.  Rounding
//is now governed by the locale.  Also notice we now use the ISO code istead of a symbol
String f = nf.format(123456.789);
System.out.println(f);

//Parse the value.  We must handle the potential ParseException
//Notice that we can not handle the '￥' mark in the parse
try {
    System.out.println(nf.parse("JPY 123.456,79"));
} catch (ParseException e) {
    e.printStackTrace();
}

The output:

JPY 123.456,79
123456.79
