import java.text.NumberFormat;

public class DecimalFormatExample {

public static void main(String[] args) {

String numStr = "1,000,000,000.999999999999999";

//Locale in_ID = new Locale("en","US");

//DecimalFormat nf = (DecimalFormat) NumberFormat.getInstance(in_ID);

DecimalFormat nf = (DecimalFormat) NumberFormat.getInstance();

nf.setParseBigDecimal(true);

BigDecimal bd = (BigDecimal) nf.parse(numStr, new ParsePosition(0));

System.out.println("bd value : " + bd);

}

}
