Twitter-Like Application with Java and JavaFX

Description

This is a Twitter-like application built using Java and JavaFX for the client-side interface. The application follows an MVC (Model-View-Controller) architecture and interacts with a PostgreSQL database through RESTful API endpoints. The server handles incoming requests, delegates them to the appropriate controllers, which in turn interact with the data access layer to process and retrieve data from the database.

Installation

To run the application, follow these steps:

1. Clone the repository to your local machine.

   git clone git@github.com:MahdiHaeri/AP_Project.git

2. Set up the PostgreSQL database and configure the connection details in the application. Open the DatabaseConnectionManager.java file located at com/example/server/data_access/DatabaseConnectionManager.java.

   package com.example.server.data_access;
   
   import java.sql.Connection;
   import java.sql.DriverManager;
   import java.sql.SQLException;
   
   public class DatabaseConnectionManager {
       private static final String JDBC_URL = "jdbc:postgresql://your_postgresql_host:your_port/your_database_name";
       private static final String USERNAME = "your_username";
       private static final String PASSWORD = "your_password";
   
       private static Connection connection;
   
       private DatabaseConnectionManager() {
           // Private constructor to prevent instantiation
       }
   
       public static Connection getConnection() throws SQLException {
           if (connection == null || connection.isClosed()) {
               connection = DriverManager.getConnection(JDBC_URL, USERNAME, PASSWORD);
           }
           return connection;
       }
   }

3. In the DatabaseConnectionManager.java file, modify the following lines to match your PostgreSQL database configuration:

   private static final String JDBC_URL = "jdbc:postgresql://your_postgresql_host:your_port/your_database_name";
   private static final String USERNAME = "your_username";
   private static final String PASSWORD = "your_password";

4. Build and run the server component.

5. Build and run the client application.

Make sure to replace the placeholders (e.g., your_username, your_database_name, etc.) with the actual values relevant to your PostgreSQL database setup.

After following these steps, users will be able to set up the database connection correctly and run your application smoothly.
