Hashing

[sravan_51]

Hello please help me with this code

here wordcnt is a hashtable

if(wordcnt.containsKey(key_value))
{
wordcnt.put(key_value,sen_cnt);
}//for words that are repeated more than once

else
{
wordcnt.put(key_value,sen_cnt);
}//word that is first appeared

The problem here is that if the word appeared for more than once its got replaced by 2nd one ...
If I want to have both the first and next appeared words what I can do?

If you want to store Object instances with String keys and
want to save all appearances of the key chronologically you can use
HashMap<String, ArrayList<Object>>:

HashMap<String, ArrayList<Object>> map = new HashMap<String, ArrayList<Object>>();

//[...]

//A word is found and assigned to the variable 'key',
//the value to store is assigned to 'value'.

ArrayList<Object> list = map.get(key); //null if it does not exist yes
if (list == null)
{
    list = new ArrayList<Object>();
    map.put(key, list);
}
list.add(value);
