## Overview

This is a beginner programming-practice repository, not a single integrated application. Its product is a collection of independent Java and Python examples that demonstrate fundamentals, small console and GUI workflows, and object-oriented modeling. The graph highlights representative runnable workflows and major documented topic branches; examples generally do not call across files. The Task example is the clearest multi-component domain workflow. Relationships for unsampled examples are omitted rather than inferred.

Main entry points: [`java/inheritance/javaswing/testroom/Main.java`](https://github.com/pandita21-r/practice-repository/blob/main/java/inheritance/javaswing/testroom/Main.java) (Task Demo), [`java`](https://github.com/pandita21-r/practice-repository/tree/main/java) (Java Fundamentals), [`java/arrays-2d/src/FitnessBMITracker.java`](https://github.com/pandita21-r/practice-repository/blob/main/java/arrays-2d/src/FitnessBMITracker.java) (BMI Data Input), [`java/inheritance/javaswing/testroom/TaskManager.java`](https://github.com/pandita21-r/practice-repository/blob/main/java/inheritance/javaswing/testroom/TaskManager.java) (Task Manager)
