## Overview

This repository is a collection of standalone Java teaching examples and homework programs, not a single application. Its principal user workflow is to run an example or homework demo, observe console output, and learn or exercise a language concept. The chapters progress through fundamentals, control flow, classes, and inheritance; homework adds small utilities and an employee console program. The graph groups representative examples rather than listing every independent sample. Relationships are included only where shown by excerpts or the source index.

Main entry points: [`src/chapter8/BoxWeight.java`](https://github.com/gornikoghosyan1/javacore/blob/main/src/chapter8/BoxWeight.java) (Weighted Box), [`src/homeworks/employee/EmployeeDemo.java`](https://github.com/gornikoghosyan1/javacore/blob/main/src/homeworks/employee/EmployeeDemo.java) (Employee Console), [`src/chapter7/TestStack2.java`](https://github.com/gornikoghosyan1/javacore/blob/main/src/chapter7/TestStack2.java) (Stack Demo), [`src/chapter8/Shipment.java`](https://github.com/gornikoghosyan1/javacore/blob/main/src/chapter8/Shipment.java) (Shipment)
