How to put values in a HashMap dynamically using a ArrayList as 'value'

Question

i have to generate different maps dynamically by passing arraylist (which is also dinamically increasing) in the value.
i want to use :
List myList=new ArrayList();
for(..........){
Map mymap=new HashMap();
myMap.put(key, myList.add(objectBean));
=====================================================================================================
this line is giving error :
myMap.put(String , myList.add(objectBean));
it says myList.add(objectBean) is boolean where as it should be put(String, ObjectBean).

Answer 1

None of this makes any sense whatsoever. You're creating a new map per loop iteration, you're using an apparently constant key, and you're adding something that's a boolean when you should be adding an ObjectBean (according to you).
