🛠️ Technologies & Tools

Technology	Purpose
☕ Java	Core programming language
🖥️ Swing	GUI application development
🗄️ JDBC	Database connectivity
🌐 `java.net`	Network programming
🔗 RMI	Distributed applications
🏢 J2EE	Enterprise Java applications
🌍 HTTP	Web communication
⚙️ Servlets	Server-side programming
📄 JSP	Dynamic web pages
🏷️ JSTL	JSP tag libraries
🔧 Git	Version control
🐙 GitHub	Source code hosting

⚙️ Prerequisites

Before running the programs, make sure you have:

Java Development Kit (JDK)
Java IDE
Basic Java knowledge
Basic SQL knowledge
Git and GitHub
Database server for JDBC programs
JDBC driver where required
Servlet/JSP-compatible web container for web applications

Check Java installation:

java -version

Check Java compiler:

javac -version

▶️ Running Java Programs

For a standard Java program:

javac Program.java

Then:

java Program

For GUI programs:

javac Program.java
java Program

For JDBC programs, configure the required database and JDBC driver before execution.

For Servlet/JSP programs, deploy the application using a compatible web container/application server.

🧪 Laboratory Learning Approach

A recommended approach for each experiment is:

Understand the Concept
        ↓
Study the Program
        ↓
Write / Modify the Code
        ↓
Compile
        ↓
Run
        ↓
Verify Output
        ↓
Understand the Implementation
        ↓
Prepare for Viva

The objective is not simply to execute the programs, but to understand the concept, implementation, execution flow, and practical application behind each experiment.
