คำอธิบาย (ภาษาไทย)

รวมตัวอย่างโค้ด แบบฝึกหัด และงานมอบหมายในวิชา Java OOP เพื่อการศึกษาและฝึกปฏิบัติ

Overview

This repository contains:

• Classroom assignments and solutions (see src/ and bin/)
• Example projects demonstrating OOP concepts (encapsulation, inheritance, polymorphism, interfaces)
• Sample data files used in exercises (Students.txt, products.csv, sales.csv)

Quick repository metadata (suggested)

• Description: Java in class — Java OOP examples
• Website: replace with your project URL
• Topics: java oop examples classroom
• Enable GitHub features: Releases, Deployments, Packages when you publish

Prerequisites

• Java JDK 8 or later
• Optional: Visual Studio Code with the Java Extension Pack

Installation and setup

1. Clone the repository:

git clone <repo-url>
cd java_in_class

2. Open the folder in Visual Studio Code (recommended) or your preferred IDE.

Build & run (command line)

Compile all sources into bin/:

javac -d bin $(find src -name "*.java")

On Windows (PowerShell / cmd), you can run:

javac -d bin src\**\*.java

Run a main class (replace <MainClass> with the fully-qualified class name):

java -cp bin com.example.Main

If a class is in the default package and files are at the root of src/, run:

javac -d bin src\Main.java
java -cp bin Main

Using Visual Studio Code

• Install Extension Pack for Java (by Microsoft) for editor support, debugging and project management.
• Use the Run code lens above main() methods or the JAVA PROJECTS view to compile and run classes.

Running examples and assignments

• Each chapter or assignment is organized under src/ and mirrored in bin/ after compilation.
• Example: to run an assignment Ass2_01.java located at src/Ass2/Ass2_01.java:

javac -d bin src/Ass2/Ass2_01.java
java -cp bin Ass2.Ass2_01

If the code uses packages, use the package-qualified class name in the java command.

Quick demo (runnable example)

An example Main demonstrating basic OOP is provided at src/example/Main.java (package example). To compile and run this demo:

Unix / WSL / Git Bash:

javac -d bin src/example/Main.java
java -cp bin example.Main

Windows (cmd / PowerShell):

Overview

This repository contains:

• Assignments and solutions organized by chapter or assignment folder under src/
• Small example programs that illustrate OOP concepts: encapsulation, inheritance, polymorphism, interfaces
• Sample data files used in exercises (Students.txt, products.csv, sales.csv)

Quick start

Requirements:

• Java JDK 8 or later
• Optional: Visual Studio Code with the Java Extension Pack

Clone and build:

git clone <repo-url>
cd java-oop-assignments

Compile all Java sources to bin/ (Unix):

javac -d bin $(find src -name "*.java")

Windows (PowerShell / cmd):

javac -d bin src\**\*.java

Run a class (replace with the fully-qualified class name):

java -cp bin package.name.MainClass

Demo (runnable example)

There is a small demo in src/example/Main.java (package example). To compile and run it:

Unix / WSL / Git Bash:

javac -d bin src/example/Main.java
java -cp bin example.Main

Windows (cmd / PowerShell):

javac -d bin src\example\Main.java
java -cp bin example.Main

Expected output:

Hi, I'm Alice, age 30.
Hi, I'm student CS101.
Student ID: CS101

Project structure

• src/ — Java source files (organized by chapter/assignment)
• bin/ — compiled class files (generated by javac)
• data/ or root files like Students.txt, products.csv — sample input data
• LICENSE — project license

Contributing

1. Fork the repository and create a feature branch.
2. Add your exercise or solution under src/, include a short description and expected output.
3. Open a pull request with a clear title and summary.

Coding conventions

• Use standard Java naming: CamelCase for classes, lowercase for packages.
• Prefer small, focused methods; include comments for complex logic.
