I need Indian currency format like 100000 as 1,00,000 , 1234 as 1,234

Question

I need Indian currency format like 100000 as 1,00,000 , 1234 as 1,234.

I have tried this code,

function currencyFormat1(id) {
    var x;
    x = id.toString();
    var lastThree = x.substring(x.length - 3);
    var otherNumbers = x.substring(0, x.length - 3);
    if (otherNumbers != '')
        lastThree = ',' + lastThree;
    var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree;
    return  res;
}

But it is working in only java script, I need this as core java code , I have tried to convert this but the

var res = otherNumbers.replace(/\B(?=(\d{2})+(?!\d))/g, ",") + lastThree;

The Java NumberFormat will give you what you want, but you can also write your own method:

public static String fmt(String s){

    String formatted = "";
    if(s.length() > 1){
        formatted = s.substring(0,1);
        s = s.substring(1);
    }

    while(s.length() > 3){
        formatted += "," + s.substring(0,2);
        s = s.substring(2);
    }
    return formatted + "," + s + ".00"; 
}

Test:

System.out.println(fmt("1234"));
System.out.println(fmt("100000"));
System.out.println(fmt("12345678"));
System.out.println(fmt("123456789"));                       
System.out.println(fmt("1234567898"));

Output:

1,234.00
1,00,000.00
1,23,45,678.00
1,23,45,67,89.00
1,23,45,67,898.00
