     HashSet hs=new HashSet();
     for(int i=0;i<str.length;i++)
     {
             hs.add(str[i]);
     }
     String arraystr1[]=(String[])hs.toArray(new String[hs.size()]);
     String updatedArrayAsStr="";

     {
         if(updatedArrayAsStr.equals(""))
             updatedArrayAsStr=arraystr1[i];
         else
             updatedArrayAsStr=updatedArrayAsStr+","+arraystr1[i];
     }
