Thank you renuka!!
I had used this method in my AMIMpl Class and i need to call this method in my ValueChangeListner
    public void ExpiryDate(){
        ViewObject vo = this.getLegalDocDetailsView1();
        Row vor = vo.getCurrentRow();
        Calendar c1;
        try {
            java.util.Date datefromtable = convertDomainDateToUtilDate((Date)vor.getAttribute("LddIssuedOn"));
            c1.setTime(datefromtable);
        } catch (SQLException e) {
            System.out.println ("Exception caught"+e);
        Number n = (Number)vor.getAttribute("LddValidDur");
        if (vor.getAttribute("LddValidFreq").equals("D")){
            c1.add(Calendar.DATE,n);   //In this i am getting error as add(int,Number) cannot invoke add(int,int) in calendar
    public java.util.Date convertDomainDateToUtilDate(Date domaindate) throws SQLException {
        System.out.println("*/*/*/*/*/*/*/*/*/");
        java.util.Date date = null;
        if (domaindate != null) {
            java.sql.Date sqldate = domaindate.dateValue();
            date = new java.util.Date(sqldate.getTime());
        return date;
    }
