## Overview

This repository is a collection of independent Java learning examples, not a single application. Its principal pattern is a small console program that accepts input (or uses fixed sample values), demonstrates a programming concept, and prints a result. The examples progress from basic decisions and loops to object-oriented modeling and behaviors. The sampled files support these individual interactions; there is no shared application entry point or runtime pipeline.

Main entry points: [`LoanEligibilityCheck.java`](https://github.com/moazzam56/java/blob/main/LoanEligibilityCheck.java) (Condition Checks), [`Loops/Forloop/StarPatterns.java`](https://github.com/moazzam56/java/blob/main/Loops/Forloop/StarPatterns.java) (For Loops), [`Loops/WhileLoop/ReverseNumberInput.java`](https://github.com/moazzam56/java/blob/main/Loops/WhileLoop/ReverseNumberInput.java) (While Loops), [`Loops/DoWhileLoop/DigitAnalysis.java`](https://github.com/moazzam56/java/blob/main/Loops/DoWhileLoop/DigitAnalysis.java) (Do-While Loops)
