-
-This repository contains a collection of beginner-friendly Java programs focused on **control flow**, including looping, conditional statements, number operations, and pattern generation. Each file is a standalone logic exercise designed to build foundational programming skills.
-
-## 📌 Overview
-
-This project includes simple yet foundational Java programs that cover:
-
-- Printing numeric ranges  
-- Checking number signs  
-- Reversing integers  
-- Comparing numbers  
-- Applying conditional logic (discount calculation)  
-- Generating patterns with nested loops  
-
-All source files are located inside:
-
-```
-/task1
-```
+This repository contains Java programs demonstrating fundamental Object-Oriented Programming (OOP) concepts such as encapsulation, inheritance, and basic class design. It includes four tasks (1.1 to 1.4), each illustrating a different OOP principle.

+## 📝 Task Overviews
 
-### 1️⃣ Print Number Range  
-![Print Number Range](screenshots/printnumrange.png)
+### **Task 1.1 — Person Class**
+- Implements a `Person` class with `name` and `age`.
+- Default age is **18**.
+- Includes constructor + method to display info.
 
-### 2️⃣ Check Number Sign

-### 4️⃣ Find Smallest of Three  
-![Smallest Number](screenshots/smallnum.png)
+### **Task 1.2 — Product Class**
+- Represents products with `pid`, `price`, and `quantity`.
+- `ProductMain`:
+  - Accepts **5 products**.
+  - Finds **highest price product**.
+  - Calculates **total expenditure**.
 
-### 5️⃣ Discount Calculator

-## ▶️ Running the Programs
+### **Task 1.3 — Account Class**
+- Implements `deposit`, `withdraw`, and `display` methods.
+- Includes default + parameterized constructors.
 
-1. Navigate to the directory:
+▶️ **Screenshot:**  
+![1.3](screenshots/1.3.png)
 
-```
-cd task1
-```
+---
 
-2. Compile the program:
+### **Task 1.4 — Inheritance (Person → Employee)**
+- `Employee` extends `Person`.
+- Adds `employeeID` and `salary`.
+- Uses `super()` for parent initialization.
 
-```
-javac FileName.java
-```
+▶️ **Screenshot:**  
+![1.4](screenshots/1.4.png)
 
-3. Run the program:
+---
 
-```
-java FileName
-```
+## ▶️ Running the Programs
 
-Example:
+### **1. Clone the Repository**
+```bash
