// Implementation of decimalSeparator()

import java.time.format.*;
import java.util.*;

public class Example1 {
    public static void main(String[] args)
    {

        DecimalStyle x = DecimalStyle.STANDARD;

        System.out.println( "Char before separation: "
            + x.getDecimalSeparator());

        char decimalSeparator = '*';

        DecimalStyle ds = x.withDecimalSeparator( decimalSeparator);
