How to create a vCard in Java

import java.io.*;
 
public class Vcard{
 
    public static void main(String[] args) throws IOException{
 
      File f=new File("contact.vcf");
      FileOutputStream fop=new FileOutputStream(f);
      
      if(f.exists()){
      String str="BEGIN:VCARD\n" +
                 "VERSION:4.0\n" +
                 "N:Gump;Forrest;;;\n" +
                 "FN:Forrest Gump\n"+

          fop.write(str.getBytes());

          BufferedReader br = null;
