Displaying Currency in Indian Numbering Format

Solution 1:

Unfortunately on standard Java SE DecimalFormat doesn't support variable-width groups. So it won't ever format the values exactly as you want to:

If you supply a pattern with multiple grouping characters, the interval between the last one and the end of the integer is the one that is used. So "#,##,###,####" == "######,####" == "##,####,####".

Most number formatting mechanisms in Java are based on that class and therefore inherit this flaw.

ICU4J (the Java version of the International Components for Unicode) provides a NumberFormat class that does support this formatting:

Format format = com.ibm.icu.text.NumberFormat.getCurrencyInstance(new Locale("en", "in"));
System.out.println(format.format(new BigDecimal("100000000")));

This code will produce this output:

Rs 10,00,00,000.00

Note: the com.ibm.icu.text.NumberFormat class does not extend the java.text.NumberFormat class (because it already extends an ICU-internal base class), it does however extend the java.text.Format class, which has the format(Object) method.

Note that the Android version of java.text.DecimalFormat class is implemented using ICU under the hood and does support the feature in the same way that the ICU class itself does (even though the summary incorrectly mentions that it's not supported).

Solution 2:

With Android, this worked for me:

new DecimalFormat("##,##,##0").format(amount);

450500 gets formatted as 4,50,500

http://developer.android.com/reference/java/text/DecimalFormat.html - DecimalFormat supports two grouping sizes - the primary grouping size, and one used for all others.

Solution 3:

here is simple thing u can do ,

 float amount = 100000;

 NumberFormat formatter = NumberFormat.getCurrencyInstance(new Locale("en", "IN"));

 String moneyString = formatter.format(amount);

 System.out.println(moneyString);

The output will be Rs.100,000.00.
