I have a arraylist appdetails.

This arraylist contains the beans Bean.getApp1(),Bean.getappr() and
Bean.getComm()
I want to add to hashtable htappdeatils. exAppBean bean1 = new exAppBean();
AppBean Bean = new AppBean();

I have a key for hashtable htappDetails
(String)Bean.getMon()+(String)Bean.getyear()

for(int j=0; j<appdetails.size();j++) {


Bean = (bean1)appdetails.get(j);
htappDeatils.put((String)Bean.getMon()+(String)Bean.getyear(),Bean.getApp1())
}

How can I add other beans Bean.getappr() and Bean.getComm() to the same
hashtable htappdetails for the same key?
