Hi all,
could anyone who knows how to solve this problem please give me
some hints?
The question is:
I have set up a Hashtable and strings as keys and empty ArrayList as
values:
Hashtable iword = new Hashtable();
while ((inLine = inputStream.readLine()) != null) {
input = inLine.split(" ",-2);
for (int i = 0 ; i < input.length; i++){
iword.put(input[i],new ArrayList());
}
}
------------------------------------------------
but, now, how can I insert more than one value for a specified
key?(i.e, insert string into the ArrayList)
Many Thanks!!!!!!
Split the task into two pieces:
1. Get the value from the Hashtable as an ArrayList reference. That is
just the same as getting e.g. a String reference from a Hashtable whose
values are String references.
2. Given an ArrayList reference, insert a String reference in the ArrayList.
