## Introduction 🎯
This course covers both **Java programming** and **Data Structures & Algorithms (DSA)**. It is designed for beginners and intermediate learners who want to excel in software development, competitive programming, and technical interviews.
---
## Why Learn Java & DSA? 🤔
✅ **Java is Versatile** – Used in web development, mobile apps, and enterprise applications.
✅ **Object-Oriented Programming (OOP)** – Makes code reusable and maintainable.
✅ **DSA is Essential** – Helps in solving complex problems efficiently.
✅ **High Demand in Jobs** – Tech giants like Google, Amazon, and Microsoft test DSA skills in interviews.

## Course Outline 📖
The course is divided into two major sections: **Java Programming** and **Data Structures & Algorithms (DSA)**.
### 🟢 **Java Programming Basics**
- Introduction to Java
- Setting Up Java & IDE (IntelliJ, Eclipse, VS Code)
- Variables, Data Types, and Operators
- Control Flow (if-else, switch-case)
- Loops (for, while, do-while)
- Functions and Recursion
- Object-Oriented Programming (OOP)
- Classes & Objects
- Inheritance
- Polymorphism
- Encapsulation
- Abstraction
### 🟡 **Data Structures**
- Arrays & Strings
- Linked Lists (Singly, Doubly, Circular)
- Stacks & Queues
- HashMaps & HashSets
- Trees (Binary Trees, BST, AVL Trees)
- Graphs (DFS, BFS, Dijkstra's Algorithm)
- Heaps & Priority Queues
- Trie Data Structure
### 🔴 **Algorithms**
- Sorting Algorithms (Bubble Sort, Selection Sort, Merge Sort, Quick Sort)
- Searching Algorithms (Linear Search, Binary Search)
- Recursion & Backtracking
- Dynamic Programming (Knapsack, Fibonacci, LCS)
- Greedy Algorithms
- Graph Algorithms (Dijkstra’s, Floyd-Warshall, Kruskal’s, Prim’s)
### 🔥 **Interview Preparation & Competitive Programming**
- Coding Interview Questions
- Time & Space Complexity Analysis
- LeetCode, CodeChef, CodeForces Problem-Solving
---
## Installation 🔧
To run Java programs, install **Java Development Kit (JDK)**.
### Install JDK (Windows, macOS, Linux)
- Download and install JDK from **[Oracle](https://www.oracle.com/java/technologies/javase-downloads.html)**
- Verify installation:
```bash
java -version
javac -version
```
## Install an IDE (Recommended)
You can write Java code using:
- [IntelliJ IDEA](https://www.jetbrains.com/idea/)
- [Eclipse](https://www.eclipse.org/)
- [VS Code](https://code.visualstudio.com/) with Java extensions
## Running Java Programs ▶️
After writing a Java program, compile and execute it using:
```java
javac HelloWorld.java
java HelloWorld
```
**Example:**
```java
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, Java with DSA!");
}
}
```
