Java Internalization - Grouping Digits
Using setGroupingSize() method of DecimalFormat, default grouping of numbers can be changed. Following example is illustrating the same.
IOTester.java
import java.text.DecimalFormat; public class I18NTester { public static void main(String[] args) { double number = 121223232473.4567; DecimalFormat decimalFormat = new DecimalFormat(); System.out.println(number); System.out.println(decimalFormat.format(number)); decimalFormat.setGroupingSize(4); System.out.println(decimalFormat.format(number)); } }
Output
It will print the following result.
1.212232324734567E11 121,223,232,473.457 1212,2323,2473.457Print
