NetBeans Projects

This repository contains a collection of NetBeans projects. Currently, it features two distinct projects: a basic calculator application (Calc) and a database connection utility (DB_Connection). Additionally, an "EAD" (Enterprise Application Development) project is included, which appears to be a hotel management system. A game project is also present, showing an initial attempt at 2D animation.

Projects Overview

This repository showcases a range of Java projects created using NetBeans IDE. These projects vary in complexity, from a simple calculator to a more elaborate enterprise application and a rudimentary game.

Calc Project

The Calc project implements a basic GUI-based calculator using Java AWT.

Features

• Basic arithmetic operations (+, -, *, /)
• Square root calculation
• Calculation history
• Undecorated Frame

Technology Stack

• Java AWT

Prerequisites

• Java Development Kit (JDK) 15 or later. (Based on Javadoc, project was compiled with JDK 15)

Installation

1. Clone the repository:

   git clone https://github.com/billodi/NetBeansProjects.git

2. Open the Calc project in NetBeans.

Usage

1. Run the GUI.calf.java file.
2. Use the buttons on the calculator to perform calculations.
3. The calculation history can be viewed by pressing the "H" button.

DB_Connection Project

This project provides a utility class for establishing a database connection to a MySQL database.

Features

• Establishes a connection to a MySQL database.
• Provides methods for executing INSERT, UPDATE, and DELETE (IUD) queries.
• Provides a method for executing SELECT queries and retrieving results.

Technology Stack

• Java
• JDBC
• MySQL

Prerequisites

• MySQL Server installed and running.
• MySQL Connector/J JDBC driver.

Configuration

1. Add the MySQL Connector/J JDBC driver to the project's classpath in NetBeans.

2. Modify the connection details in DB_Connection/src/DBMS/dbms.java to match your database configuration:

   String url = "jdbc:mysql://localhost:3306/";
   String un = "root";
   String pw = "";
   c = DriverManager.getConnection(url+"DatabaseName"+"?useSSL=false",un,pw);

   • Replace "DatabaseName" with the name of your database.
   • Set the username (un) and password (pw) accordingly.

Usage

1. Import the DBMS package into your Java code.

2. Use the dbms.iud() method to execute INSERT, UPDATE, or DELETE queries:

   try {
       DBMS.iud("INSERT INTO your_table (column1, column2) VALUES ('value1', 'value2')");
   } catch (Exception e) {
       e.printStackTrace();
   }

3. Use the dbms.search() method to execute SELECT queries:

   try {
       ResultSet rs = DBMS.search("SELECT * FROM your_table");
       while (rs.next()) {
           // Process the result set
           System.out.println(rs.getString("column1"));
       }
   } catch (Exception e) {
       e.printStackTrace();
   }

EAD Project

The EAD project is an Enterprise Application Development project that implements a hotel management system.

Features

• User authentication (Login and Registration for Staff)
• Admin Access
• Customer Information Management (Add, Update, Delete, Search)
• Room Booking
• Food Order Management
• Payment Bill Generation

Technology Stack

• Java
• Swing (GUI)
• JDBC (Database Connectivity)
• com.toedter.calendar
• org.jdesktop.swingx
• Netbeans IDE (For UI design assistance)
• Jasper Reports

Prerequisites

• Java Development Kit (JDK 8 or later)
• MySQL database server
• JasperReports library
• toedter Calendar library
• swingx library

Configuration

1. Ensure that the required libraries (JasperReports, toedter Calendar, and Swingx) are included in the project's classpath within NetBeans.
2. Update database connection string in src/model/DBM.java:

 Class.forName("org.sqlite.JDBC");
            c = DriverManager.getConnection("jdbc:sqlite:hms.db");

Usage

1. Run PreLogin.java to set up admin credential.
2. Run the Login.java class to start the application.
3. Use the GUI to manage customer information, bookings, food orders, and payments.

game Project

An early attempt at making a simple 2D game with character animation.

Features

• 2D character animation (idle, run, jump, attack)
• Key press movement (right/left)
• Basic sprite scaling

Technology Stack

• Java Swing

Prerequisites

• Java Development Kit (JDK)
• An IDE that supports Java Swing projects (like NetBeans or IntelliJ IDEA)

Usage

1. Open the project in NetBeans or your preferred IDE.
2. Run the GUI.Test1.java or GUI/testmanual.java file.
3. Press the 'h' and 'j' keys for animations. Arrow keys provide movement.
