        String name ="rami is good boy, and he is working for andorid,is completed";
    int lastSlash = name.lastIndexOf("is");
    String start = name.substring(0, lastSlash);
    String end = name.substring(lastSlash + 1, name.length());
    StringBuffer sb = new StringBuffer(name);
    sb.replace(start.length(), name.lastIndexOf(end)+1, "");

    System.out.println(sb.toString());
