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:
if ( map.containsKey(temp))

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...

Hi all,
I have problem finding the .NET equivalent of HashMap in
C++ STL.
I CANNOT use Hashtable because I want (there will be more
than one objects for the same key) objects with the same
key to be hashed into the same bucket and end up with all
the objects with the same key being in the same group.

Hi,
is there anything in the C# language that will allow you to retrieve a
value by a key, sort of like those in java? for instance
Object o = map.get("somekey");
i know there as to be something like this, but can't find it in
System.Utils. I have seen HashTable, but you must enumerate thru all
items and do a comparison until you find the key you are looking for
apparently.

I'm doing up a school project using java, and am a little new to it (I've
worked with other languages for years though).
I've seen code posted by the instructor using HashMap like this...
public HashMap<Position, Integer> boardNumbers;
.... and ...
HashMap<Integer, Integer> allNumbers = new HashMap<Integer, Integer>();

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?

I could have this done in php in three lines of code but in Java here's what I need to do:
English
Looping through list of words I call a function that returns a HashSet of movie titles that contain that particular word. I want to insert these titles into a HashMap with their value being a counter of how many times this title occured.
(if two words return the same title, that title's value (counter) would be 2)
Relative Code:

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>();

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
