[JAVA] Can someone explain how this code works? public String solution(String word) {String reversedString = word.chars().mapToObj(ch -> (char)ch).reduce("", (tempStr,ch) -> ch+tempStr, (str1,str2) -> str2+str1);return reversedString;}
Java Programming This week's project involves a text file with that holds all of the novel Don Quixote*, by Miguel Cervantes. The text file has been heavily processed. It contains only lowercase letters, spaces, and new lines. That is a good format for counting words. Write code that reads through the text file one word at a time using a Scanner, and the next() method. Put the words into a HashMap, where the words are used as keys, and the values are Integers used to keep track of how many times the words occur in the text. If the text was "one fish two fish red fish blue fish one two three" then the HashMap would look like this: key value "one".... 2 "fish"... 4 "two".... 2 "red".... 1 "blue"... 1 "three".. 1 Once you have created such a HashMap for the whole of the text you can write logic that prints out the answers to these questions: How many times does each of…

I have the following JAVA code using JFRAME: String[] headers = {"Username", "First Name", "Middle Name", "Last Name"}; JSONArray jsonArray = readJSONFile("src/registration.json");for (int i = 0; i < jsonArray.size(); i++) {JSONObject obj = (JSONObject) jsonArray.get(i);String uName = (String) obj.get("username");String fName = (String) obj.get("firstName");String mName = (String) obj.get("middleName");String lName = (String) obj.get("lastName");Object[] row = {uName, fName, mName, lName};tableModel.addRow(row);} My code displays data for each registrant in a table format. Please add an action listener to my GUI code that will delete the selected data from the JSON file.
