I have a key value pair in Hashmap in Java, I am traversing Map in following way.
ArrayList<String> mysection = new ArrayList<String>();
ArrayList<String> temp = new ArrayList<String>();
Iterator it = Map.entrySet().iterator();
while (it.hasNext()){
Map.Entry pairs = (Map.Entry)it.next();
System.out.println(" = " + pairs.getValue());
mysection.add(pairs.getKey().toString());
temp.add(pairs.getValue().toString());
it.remove(); // avoids a ConcurrentModificationException
}
This seems to be good, but the loop runs one time and creates a long string of value associated with the key. I don’t want in that way. I want each value to be stored in ArrayList but it’s not happening this way. All value is stored in the 1st index itself.
Secondly even if I try to bifurcate I don’t find a suitable way. First I thought of splitting the string via “,” operator but the string itself contains several “,”
Please suggest what should I do specifically for the 1st question, I don’t want the all value as single string.
Thanks

OK, i got it done…actually there are many ways to iterate over maps, this one is not the best suited for what i want. So changed the implentation of iteration of another method now its working smooth.
