About this gig

Need help with Java Object-Oriented Programming? You are in the right place.

I am a Computer Science student specialized in Java development. Whether you have a nasty bug (NullPointerException) or need a complete algorithm built from scratch, I deliver clean, optimized, and heavily commented code.

My Expertise in Java:

  • Core OOP Concepts: Classes, Interfaces, Inheritance, Polymorphism, Abstraction.
  • Data Structures & Collections: ArrayList, HashMap, LinkedList, Trees.
  • File Handling & Exceptions: Try/Catch blocks, reading/writing TXT or CSV files.
  • Algorithms: Sorting, Searching, and Custom Logic.

What you will get:

  1. Functional, compilation-ready Java code.
  2. Detailed inline comments to help you understand the logic.
  3. Fast response time and weekend availability.

NOTE: This gig is for core Java (Console applications / Logic). I do not handle complex Web Frameworks (Spring) or heavy GUIs (JavaFX) here.

Please contact me BEFORE placing an order so we can discuss your deadline and requirements!
