for (int i = 0; i < sizeListRow; i++) {
				int sizeListCol = listB.size();
				for (int j = 0; j < sizeListCol; j++) {
					// Get the First List B
					List<IBean> list = listB.get(j);
					(weanames.get(i).get(j)).add((((Weapons) list.get(i)).getWeaponName());
				}
			}

How do i add values to list of list of strings??

[Joel Christophel]

List<IBean> list = listB.get(j)

How can 'list', which is a List, be equal to the value of a list index?

ListB is a List<List<IBean>>

You get a reference to the list of strings from the list of list of strings (eg by calling it's get() method) and then call it's add() method passing in the String you want to add.
Do you have a list of list of strings in the code shown?

BTW line 6 is overly complicated by you trying to do way too much on one line. I suggest you break into at least 3 lines, it will make your code easier to read and less prone to bugs.
