JSR 354 Java money api indian format

 JSR 354 – is proposed as standard api for  Currency and Money handling in java.

Here is how we can format amount to indian format as by default indian currency is formatted as US currency.

Dependency setup:

  
      javax.money
      money-api
      1.0.3
  
  
      org.javamoney
      moneta
      1.3
      pom
    

Default formatting:

 @Test
 public void defaultIndianFormat() {
     MonetaryAmount indianMoney = Monetary.getDefaultAmountFactory()
       .setCurrency("INR").setNumber(100000.12345).create();
     MonetaryAmountFormat amountFormat=MonetaryFormats.getAmountFormat(new Locale("en-IN"));
     System.out.println("Default indian money format ->"+amountFormat.format(indianMoney));
 }

Output: Default indian money format ->INR 100,000.12

 @Test
 public void testIndianFormat() {
  
  AmountFormatQuery query = AmountFormatQueryBuilder.of(new Locale("en","IN"))
    .set(AmountFormatParams.GROUPING_SIZES, new int[]{3,2}).build();
    MonetaryAmountFormat format = MonetaryFormats.getAmountFormat(query);
    System.out.println(format);
    
    MonetaryAmount amount =
    Monetary.getDefaultAmountFactory()
    .setCurrency("INR")
    .setNumber(100000.123456).create();
    String formatted = format.format(amount);
    System.out.println("indian format output -->> "+formatted);
 }

Output: indian format output -->> INR1,00,000.12
