Implement Paging and following Filters in your Ecommerce class project using MySQL and PHP. Write down PHP code only.

we are going to create a new subclass of the SimpleGeometricObject class, namedTriangle. Copy the source code of the SimpleGeometricObject class from the following link:   https://liveexample.pearsoncmg.com/html/SimpleGeometricObject.html   TASK 1: Create a Triangle class that extends the SimpleGeometricObject class in Eclipse, followingthe below UML diagram. Use the following formula to calculate the area of a triangle: A = 1/2 × base × height   TASK 2: Create a TestTriangle class in an individual .java file. In the main method,(1) Create a Triangle object with default base and height values.(2) Create a Triangle object with specified base = 3 and height =4.   TASK 3: Add a toString() method to the Triangle class. In this toString() method,(1) Print the base, height, and area of a Triangle object.(2) Call the toString() method of the superclass using the super key word.Then, in the main method of the TestTriangle class, make the two Triangle objects that youcreated in Task 2…

I'm interested in creating a digital personal assistant similar to Alexa and Siri, which can efficiently manage schedules. Specifically, I want to design a tool in Java that allows users to find events during a certain time period. This tool should also enable users to add and cancel events as their schedules change. To achieve this, I plan to use a SkipListMap class with specific operations (get, put, remove, subMap) and a DoublyLinkedList class. Additionally, I'll use the FakeRandomHeight class for debugging and testing. Could you provide guidance on how to approach this project, especially in terms of implementing the SkipListMap class and managing event data efficiently?

You will implement some methods in the UndirectedGraph class. The UndirectedGraph class contains two nested classes, Vertex and Node, you should NOT change these classes. The graph will store a list of all the vertices in the graph. Each vertex has a pointer to its adjacent vertices. To get started, import the starter file, Undirected.java into the graphs package you create in a new Java Project. Please do not change any of the method signatures in the class, but you can add any helper methods you deem necessary. Implement the methods described below. You are free to test your code however you prefer. Vertex Class (DO NOT EDIT)The vertex class holds information about the vertices in the graph. It has an int val, a Vertex next that refers to the next vertex in the list of vertices (not necessarily an adjacent vertex), and a Node edge that starts the list of adjacent vertices. Node Class (DO NOT EDIT)This is a simple class to represent an adjacency list of a vertex in the graph.…

Please Code in JAVA. Type the code out neatly. Add comments . (No need for long comments). Dont add any unnecesary code or comments. Do what the attached file says. And call it a day. Thanks !

Q3.There are special semaphores called counting semaphores. What kinds of things are they used for?

Can we find somewhere that gives a more detailed description of the HTML post and get methods? Considering that, why not?

I got errors in parser.java. How to create methods in TokenHandler.java for getCurrentToken(), consumeToken(), getLastMatchedToken()? Please create these methods in TokenHandler.java. Fix the error for programNode that is attached. Below is TokenHandler.java   TokenHandler.java import java.util.LinkedList; import java.util.Optional; import mypack.Token.TokenType;   public class TokenHandler {   private LinkedList<Token> tokens;// List of tokens       public TokenHandler(LinkedList<Token> tokens) {         this.tokens = tokens;     }       public Optional<Token> Peek(int j) {         if (j < tokens.size()) {             return Optional.of(tokens.get(j));         } else {             return Optional.empty();         }     }       public boolean MoreTokens() {         return !tokens.isEmpty();     }       public Optional<Token> MatchAndRemove(TokenType t) {         if (MoreTokens() && Peek(0).get().getType() == t) {             return…
