Course Description

Welcome to Absolute Introduction to Object Oriented Programming in Java.

This course is designed to be slow-paced, simple and rich in demystifying the question: What really is an object in computer programming?

These course lectures serve as a crucial foundation for mastering the concept of OOP (Object Oriented Programming).

If you have ever written a Java class before and ran the program in Eclipse but did not quite understand what is going on behind the scenes, then this course is for you. By the end of these videos, you will understand the difference between a class, and an object.

You'll know how objects are constructed and what exactly happens when the program is run. We will also go over important OOP (Object Oriented Programming) techniques such as inheritance and polymorphism.

What Makes This Course Stand Out?

  1. Short & Practical: We cover Java fundamentals topics in Object Oriented Programming to build your confidence.

  2. Beginner-Friendly: No prior programming experience? No worries! We guide you through every core concept, ensuring a strong foundation in Java.

  3. Clear Explanations & Step-by-Step Guidance: Complex topics such as Java Stack and Heap are broken down into an easy-to-understand lesson.

Why This Course Is Essential:

The Absolute Introduction to Object Oriented Programming in Java Course is designed to help you master the fundamental components for mastering the Core Java development concepts. Especially if you're going for a job interview or have a Java Project that needs your best performance. This course assumes no prior Java experience so prior Java so it will take you from zero to hero!

The course topics mainly focus on Object Orientation which I think is not stressed enough in other Java courses so I've got a complete focus on that throughout the lectures. You'll get plenty of practice writing classes and interfaces as well as countless methods with loops and if-else statements, as well as how to debug software using Eclipse.

Topics covered in the Absolute Introduction to Object Oriented Programming in Java course:

  • Basics of Java Program

  • Classes and Objects in Java

  • Program Flow

  • Constructors

  • Java Stack and Heap

  • Reference and Instance Variables

  • Inheritance and Polymorphism

  • Interfaces and Abstractions

  • Abstract Class

Key Benefits of Java Mastery

  1. Versatility & Demand: Java powers everything from enterprise applications to Android development. Mastering it opens up numerous career paths.

  2. Strong Foundation: A solid grasp of OOP, data handling, and concurrency sets you up to learn any new language or framework with ease.

  3. High Earning Potential: Skilled Java developers remain in high demand across multiple industries.

  4. Real-World Skills: Practical projects and industry-relevant examples ensure you can hit the ground running in any Java-related role.

KEY TAKEAWAY

Don’t miss the opportunity to build a strong foundation in Java—a versatile, high-demand language used by top companies worldwide. By the end of this course, you will be ready to work with multiple classes in Java and be prepared to take the more challenging and top ranked course: Master Object Oriented Design in Java - HW + Solutions

Instructor Details

Job Ready Programmer

You can’t learn programming from reading books or online fill-in-the-blank type tutorials. Especially the online tutorials with browser based exercises where you code directly in your browser. The problem with that approach is that it doesn’t provide practical experience. It provides an illusion of learning something as it tugs you along to complete an assignment that’s more of a fill-in-the-blank type problem. A student feels like they’ve learned something but that knowledge does not stick. Unfortunately that experience will not help in an interview nor an actual project. Valuable time ends up going to complete waste. At JRP (JobReadyProgrammer), we don’t follow hype. We do what works! We take a traditional route to teaching how to code advancing slowly & patiently in the lectures often repeating key concepts in multiple different ways to help students really solidify the knowledge and mold their foundation to discover how to code properly and then boy do we test the skills! Students are put right in the middle of a practical real-world programming assignment to apply everything they've learned. So enough of those “key in the next few commands to fill in the puzzle and we’ll advance you” kind of tutorials. Here you’ll need to roll up your sleeves and get to work on solving practical programming assignments.

You explain java well. I come from the 3GL world, especially FORTRAN. It seems like you can write "object oriented" code in FORTRAN by just using STRUCTURE and RECORD definitions. Probably, if you did, the FORTRAN executable would execute much faster than java could.

By Gabriela Mate on 9/9/2022

The instructor was pretty boring. Skipped over a lot of basic concept because he assumed previous knowledge. The course too short for important concepts such as these.

so far so good
