# 🚀 Java & DSA Mastery Repository
Welcome to the **Java & Data Structures & Algorithms (DSA) Mastery Repository**! 🎯 This repository is a curated collection of concepts, implementations, and problem-solving approaches in **Object-Oriented Programming (OOP) and DSA using Java**. Whether you're a beginner or an experienced developer, you'll find something valuable here! 🔥
## 📂 Folder Structure
### 🔷 OOPS (Object-Oriented Programming in Java)
Master the four pillars of OOP: **Abstraction, Encapsulation, Inheritance, and Polymorphism**.
📌 **Key Topics:**
- **Abstraction/** - Implementing abstract classes and interfaces.
- **Encapsulation/** - Data hiding and access modifiers.
- **Inheritance/** - Understanding parent-child relationships.
- **Polymorphism/** - Method overloading and overriding.
- **Singleton/** - Implementing the Singleton design pattern.
- **Wrapper.java** - Exploring wrapper classes in Java.
- **Garbage.java** - Memory management and garbage collection.
- **Generics/** - Type safety and reusability.
- **ExceptionHandling/** - Handling runtime errors effectively.
- **Access/** - Understanding access specifiers.
- **Contructor.java & Contructor.class** - Understanding constructors and their usage.

### 🔷 DSA (Data Structures & Algorithms in Java)
**Master problem-solving techniques and optimize your code with efficient algorithms!**
📌 **Key Topics:**
- **Sorting & Searching:** Binary Search, Selection Sort, Bubble Sort, and more!
- **StackAndQueues/** - Implementation of stacks & queues from scratch.
- `CustomStack.java` - Implementation of stack.
- `CustomQueue.java` - Implementation of queue.
- `DynamicStack.java` - Stack with dynamic memory allocation.
- `InBuildExamples.java` - Built-in Java stack & queue examples.
- `StackException.java` - Custom exception handling in stacks.
- **Binary Search Variants:**
- `BinarySearch.java` - Standard binary search implementation.
- `OrderAgnosticBinarySearch.java` - Works on both sorted (ascending/descending) arrays.
- `RotatedBinarySearch.java` - Searching in rotated sorted arrays.
- **2D Arrays & Matrices:**
- `SearchIn2DArray.java` - Searching in a matrix.
- `RowColMatrix.java` - Matrix traversal techniques.
- `SortedMatrix.java` - Searching in a sorted matrix.
- **Mathematical & Logical Problems:**
- `EvenDigits.java` - Finding numbers with even digits.
- `FindMin.java` - Finding the minimum number in an array.
- `FindPeakInMountain.java` - Finding peak elements in mountain arrays.
- **Linked Lists:** Implementation of singly, doubly, and circular linked lists.
