java - Change the format of a number to readable in currency format? -


in application, want able to:

make number 300000 appear 300,000 usd ? don't want "usd" ,

i want able choose own currency too.

to described, try counting every 3 digits (chars) end of string number , add ','. then, @ end, add " usd" (space makes nicer).

example code:

int toformat = 1563992; string output = "" + toformat; int counter = 0; (int index = output.length() - 1; index > 0; index--){     counter++;     if (counter % 3 == 0){         counter = 0;         output = output.substring(0,index) + "," + output.substring(index);     } }  output += " usd"; // or whatever want system.out.println(output);

outputs: 1,563,992 usd
