Write a java class that implements a Trie of uppercase alphabetical letters. A trie is a data structure that permits efficient lookup of words in a dictionary (See figure). You may need to make two classes i.e. TrieNode and Trie. Your trie should support the following operations: i need one method in the tree prefix (trie) class which is if you use helper method include it please: allWordsPrefix(String p) [return type String[] ] = this method returns all words whose prefix is ‘p’. the method should return and array

Write a java class that implements a Trie of uppercase alphabetical letters. A trie is a data structure that permits efficient lookup of words in a dictionary (See figure). You may need to make two classes i.e. TrieNode and Trie. Your trie should support the following operations:
i need one method in the tree prefix (trie) class which is if you use helper method include it please:
allWordsPrefix(String p) [return type String[] ] = this method returns all words whose prefix is ‘p’.
the method should return and array of a given prefix, so for example if i pass the string ''TA'' into the method it should return an array with all words starts with the given prefix.

You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
- in java : you need to start implementing a class for creating and storing Binary SearchTrees (BST). Each node of this BST will store the roll number, name and CGPA of a student.The class definitions will look like:class StudentBST;class StudentNode {friend class StudentBST;private:int rollNo;string name;Student’s CGPAStudentNode* left; // Pointer to the left subtree of a nodeStudentNode* right; // Pointer to the right subtree of a node};class StudentBST {private:StudentNode* root; // Pointer to the root node of the treepublic:StudentBST(); // Default constructor}; Write a menu-based driver function to illustrate the working of different functions of theStudentBST class. The menu should look like:1. Insert a new student2. Search for a student3. See the list of students4. QuitEnter your choice:Computer Science Write a program in the Java language that includes: 1. A class for books, taking into account the encapsulation and getter, setter. 2. Entering books by the user using Scanner 3. LinkedList class for: (Adding a new book - Inserting a book- Searching for a book using the ISBN Number - Viewing all books,delete book). 4. Serial number increases automatically with each book that is entered. 5. Printing the names of books is as follows: Serial - ISBN - Name - PubYear - Price - Notes. 6-Design a main menu that includes: • Add Book • Insert Book • Delete Book • Search . Display . ExitJava Your Java project has a class named Tree with the current class header: public class Tree { Now you want to make a collection of Tree objects and be able to sort them. Rewrite the entire class header to make this possible. b. In a UML class diagram for a class named Computer that has a private String field named model, you want to represent a standard getter. Write the line you would enter to do this. (To make the spacing work, use the general rule to put a space between any symbol and the words to either side of it.)

Your task is toprovide the implementation of following methods.constructorinsertRecord() functionupdateRecord() functioncountOfPassedStudents()showData() functioninside main() function, create an object of BST class.Insert the following data and create the BST according to the marks.● 19L-1941, 71 should be the root node● 19L-1942, 62● 19L-1943, 67● 19L-1944, 54● 19L-1945, 58● 19L-1946, 45● 19L-1947, 29● 19L-1948, 76● 19L-1949, 81● 19L-1950, 92Update the data of following record● Marks of 19L-1944 are 54. Update the marks to 47● Marks of 19L-1949 are 81. Update the marks to 85Call the countOfPassedStudents(). You can either display the count in the same function orreturn the value to main function.Call the showData() function to display all the records of BST in preorder traversal.Note: It is not mandatory to create a template classAdd the following method in the BST class that returns aniterator for traversing the elements in a BST in preorder./** Return an iterator for traversing the elements in preorder */java.util.Iterator<E> preorderIterator()Java programming language I have to create a remove method that removes the element at an index (ind) or space in an array and returns it.

- Create java program reads words from a text file, creates a ItemNode instance for each word (use type String), adds each NodeItem instance to a SinglyLinkedList class instance, then traverses this list recursively to display the words in the reverse original (FIFO) order they were added in. For instance, if you added the Strings "one", "two", "three" in that order, code the SinglyLinkedList print() method to display "one two three". You can do this by recursively traversing the list, then displaying each item as you return from each activation record. For instance, data "one two" should be displayed as "two one".Java Code: Create a Parser class. Much like the Lexer, it has a constructor that accepts a LinkedList of Token and creates a TokenManager that is a private member. The next thing that we will build is a helper method – boolean AcceptSeperators(). One thing that is always tricky in parsing languages is that people can put empty lines anywhere they want in their code. Since the parser expects specific tokens in specific places, it happens frequently that we want to say, “there HAS to be a “;” or a new line, but there can be more than one”. That’s what this function does – it accepts any number of separators (newline or semi-colon) and returns true if it finds at least one. Create a Parse method that returns a ProgramNode. While there are more tokens in the TokenManager, it should loop calling two other methods – ParseFunction() and ParseAction(). If neither one is true, it should throw an exception. bool ParseFunction(ProgramNode) bool ParseAction(ProgramNode) -Creates ProgramNode,…This Java code does not run, it has some errors and it needs a main method, please fix it. import java.io.*; class DecisionTree { /* NESTED CLASS */ private class BinTree { /* FIELDS */ private int nodeID;private String questOrAns = null;private BinTree yesBranch = null;private BinTree noBranch = null; /* CONSTRUCTOR */ public BinTree(int newNodeID, String newQuestAns) {nodeID = newNodeID;questOrAns = newQuestAns;}} /* OTHER FIELDS */ static BufferedReader keyboardInput = newBufferedReader(new InputStreamReader(System.in));BinTree rootNode = null; /* Default Constructor */ public DecisionTree() {} /* CREATE ROOT NODE */ public void createRoot(int newNodeID, String newQuestAns) {rootNode = new BinTree(newNodeID,newQuestAns);System.out.println("Created root node " + newNodeID);} /* ADD YES NODE */ public void addYesNode(int existingNodeID, int newNodeID, String newQuestAns) {// If no root node do nothing if (rootNode == null) {System.out.println("ERROR: No root node!");return;} // Search…
