Example

Open Compiler

importjava.text.DecimalFormat;publicclassI18NTester{publicstaticvoidmain(String[] args){double number =121223232473.4567;DecimalFormat decimalFormat =newDecimalFormat();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
1212,2323,2473.457
