Introduction

This project is a compilation of Java assignments aimed at practicing and improving problem-solving, algorithm design, and foundational programming skills. Each assignment highlights a specific area of programming, including searching, sorting, string manipulation, and logical operations, offering practical experience with Java fundamentals.

The tasks are thoughtfully designed to challenge beginner and intermediate-level programmers, equipping them with the skills needed for real-world problem-solving situations.

Prerequisites

Before running the assignments, ensure the following tools are installed on your system:

• Java Development Kit (JDK)

  • Version 8 or higher. For my case, I have used** JDK 17**
  • Download JDK from Oracle's Official Website.

• Java IDE

  • Any Java Integrated Development Environment (IDE), such as:
    • IntelliJ IDEA
    • Eclipse
    • NetBeans
    • Visual Studio code

Problem Solving Highlights

This project features solutions to various Java programming assignments, covering a wide range of topics:

• Search and Sorting Algorithms: Identify the 2nd highest CGPA, implement binary search, and perform manual sorting.
• Random Number Operations: Generate random numbers and determine minimum/maximum values.
• Pattern Printing: Programmatically create complex output patterns.
• String Manipulations: Count words, characters, vowels, and consonants; remove vowels from strings.
• Custom Algorithms: Break down currency notes, validate IP addresses, and verify binary strings.
• HTML Parsing: Extract transaction IDs using string operations.
• Password Generation: Generate secure passwords following custom rules.
• Mathematical Operations: Solve logical problems such as distributing question marks and calculating discounts.

All solutions are implemented programmatically without built-in shortcuts (e.g., Arrays.sort()), fostering a deeper understanding of core algorithms and problem-solving techniques.
