Programming Languages Ranking System

This project implements a system to rank programming languages based on various attributes, demonstrating key object-oriented programming concepts and algorithm implementations.

Project Overview

The system ranks programming languages like Python, C++, and Rust in a tabular format using randomly generated data. The implementation showcases:

• Object-Oriented Programming principles (Inheritance, Polymorphism, Encapsulation)
• Sorting algorithms (Merge Sort, Insertion Sort)
• Binary Search implementation
• Clean code practices with Javadoc documentation

Learning Experience: CI Workflow Implementation

As part of extending my learning, I implemented my first Continuous Integration (CI) pipeline using GitHub Actions. This experience taught me:

• How to set up automated testing workflows
• Working with JUnit 5 in a CI environment
• Managing build and test dependencies without build tools
• Understanding the importance of automated testing in software development

The CI pipeline automatically:

1. Compiles all Java source files
2. Runs JUnit tests on every push and pull request
3. Reports build and test status

This hands-on experience with CI/CD practices has given me valuable insight into modern software development workflows and quality assurance practices.

Features

• Merge Sort implementation
• Insertion Sort implementation
• Binary Search implementation
• Custom Datapoint class for handling multi-column data
• Generic type support for sorting and searching operations
• Comprehensive JUnit tests for all algorithms
• Continuous Integration via GitHub Actions

Usage

The project provides the following main classes:

• SortAndSearch: Contains the implementations of sorting and searching algorithms
• Datapoint: A class for handling multi-column data points with comparable functionality
• Table: Manages collections of data points
• DataProcessing: Handles data processing operations
• TextEditor: Provides text editing capabilities

Testing

The project includes a comprehensive test suite using JUnit 5. Tests cover:

• Merge Sort functionality
• Insertion Sort functionality
• Binary Search with various scenarios
• Edge cases (empty lists, single-element lists)

To run the tests locally:

1. Download JUnit Platform Console Standalone JAR
2. Compile the source and test files
3. Run the tests using the JUnit Platform Console

wget https://repo1.maven.org/maven2/org/junit/platform/junit-platform-console-standalone/1.9.2/junit-platform-console-standalone-1.9.2.jar
javac -cp junit-platform-console-standalone-1.9.2.jar:. *.java tests/*.java
java -jar junit-platform-console-standalone-1.9.2.jar --class-path tests:. --scan-class-path
