please edit and change my program to do the Following. You don't need to explain just change my program to do the following please. I need help with my program. It needs to: Use the context-free grammar to develop a language model that can be used to generate coherent and grammatically correct sentences in American English. Incorporating semantic information into the context-free grammar: Expand the context- free grammar to incorporate semantic information, such as word meaning and context, to generate more meaningful sentences in American English. import java.util.*; import java.util.stream.Collectors; public class CFG {     private static Map> rules;     public static void main(String[] args) {         rules = new HashMap<>();         initializeGrammarRules();         String sentence = generateSentence("S");         System.out.println(sentence);     }     private static void initializeGrammarRules() {         rules.put("S", Arrays.asList("NP VP"));         rules.put("NP", Arrays.asList("Det N", "Det AP N"));         rules.put("AP", Arrays.asList("Adj", "Adj AP"));         rules.put("VP", Arrays.asList("V NP", "V NP PP"));         rules.put("PP", Arrays.asList("P NP"));         rules.put("Det", Arrays.asList("the", "a", "an"));                  rules.put("N", Arrays.asList("Animal", "Object"));         rules.put("Animal", Arrays.asList("cat", "dog"));         rules.put("Object", Arrays.asList("book", "tree"));                  rules.put("Adj", Arrays.asList("Size", "Color"));         rules.put("Size", Arrays.asList("big", "small"));         rules.put("Color", Arrays.asList("brown", "green"));                  rules.put("V", Arrays.asList("AnimalAction", "ObjectAction"));         rules.put("AnimalAction", Arrays.asList("chased", "ate"));         rules.put("ObjectAction", Arrays.asList("read", "climbed"));                  rules.put("P", Arrays.asList("in", "on", "under", "above"));     }     private static String generateSentence(String symbol) {         List alternatives = rules.get(symbol);         if (alternatives == null) {             return symbol;         }         String expansion = alternatives.get(new Random().nextInt(alternatives.size()));         String[] symbols = expansion.split("\\s+");         String sentence = Arrays.stream(symbols)                 .map(CFG::generateSentence)                 .collect(Collectors.joining(" "));                  // Apply basic capitalization and punctuation rules.         return sentence.substring(0, 1).toUpperCase() + sentence.substring(1) + ".";     } }
