Optimize Storage:Implement efficient data structures like tries or hash maps. Include Frequencies:Store the frequency of each word’s usage to improve suggestion accuracy. Code Example in Kotlin: val dictionary = HashMap<String, Int>() dictionary["example"] = 5000 dictionary["sample"] = 3000 Er...
Hashmap, ArrayList, Static Map, Vectors, etc are the most used Java collection framework elements. There are infinite number of scenarios you could use
.map(map.entry::getkey) .orelse(','); assertequals(',', detecteddelimiter); } in this method, we use replace() to remove the delimiter from the line, and the difference in length() counts how many times each delimiter appears. we then store the counts in a hashmap . finally, we...

How to find the highest repeated word from a File in Java Here is the Java program to find the duplicate word which has occurred a maximum number of times in a file. You can also print the frequency of words from highest to lowest because you have the Map, which contains the word and...
Please note that if you are working on a very high concurrent application with a very high frequency of updates in ConcurrentHashMap, you should consider increasing the concurrency level by more than 1, but again it should be a well-calculated number to get the best results. ...
