Hey Guys,
I'm hoping you could help me out here. I'm confused on how to use HashMap. I'm trying to use HashMap or HashTable to count words in a JTextArea. I have two text areas, one for editable and the other is not. So, I read a txt file into the JTextArea and I need to count how many words in that file.
Any ideas?

Any ideas?
Sure; if you know how to figure out how to extract words from a String, the
following little snippet can count them for you: -
public class WordCounter {
-
private Map<String, Integer> words= new HashMap<String, Integer>();
-
public void put(String word) {
-
Integer n= words.get(word);
-
if (n == null) // word not yet in map
-
n= Integer.valueOf(0);
-
map.put(word.n+1); // update count
-
}
-
// etc. etc.
-
}
-
kind regards,
Jos

I have a HashMap that is storing form data that will later be inserted
into a database. I have been able to create the HashMap just fine, but
I wanted to be able to take my HashMap and just "dump" it out to the
screen to make sure that everything is working as I expect. (It was
really to easy to code so I think that I may be mising something).
This is a piece of the code where I am updating the HashMap:

Hi,
I'm trying to loop over the elements in a hashmap of the
STL-implementation by SGI. The point is, that because the key/value pair
is stored as std::pair in the COntainer, the code becomes very ugly
and unreadable soon. I'm aware that there exists the for_each-template,
but this doesn't make the code any better because the body of the
for-loop must then live in an extra function (consider two nested
loops). Now I tried to mimic the...

Hello, I need help. I have the following hashmap:
HashMap<HashMap<Dimension, Integer>, String> mapList = new HashMap<HashMap<Dimension, Integer>, String>();
I want to extract Dimesion from the key, where the Integer is "1", and String from the value.
How could I iterate it?
I wrote that, but it doesn't work at the way I expected:
HashMap<Dimension, String> singleValues = new HashMap<Dimension, String>();

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
