    Default Classes/Object Beginner Help

    Hi, i'm just starting to learn to to make classes that work together and how to make objects in Java. I've read many articles and in a book on how to make and use these things but they all aren't very friendly to beginners. Can anyone supply me with a quick lesson and examples on how to use classes and objects that's easy to understand (Your own lesson/code examples/or internet links would all work). Thanks!

    The best way to learn it is to use it. It's good that you're making classes that work together. Can you post that code and ask questions about what you don't understand or would like to understand better?

    I agree with GregBrannon. If you read articles w/o practice, it's not the right way. As first step, create a simple Java program with several classes, object instances according to your feel how it should be designed. It doesn't matter if you make some OOP mistakes. Then read the books about them and correct your code. It's the only way to retain knowledge. (I tried to read books beforehand also, but it doesn't work)

    I agree totally with the hands-on approach with learning new stuff.

    However, here are some links that might come in handy when trying to figure out the terminology and concepts behind OOP.

    Oracle's own easy to grasp explanations and examples:
    Lesson: Object-Oriented Programming Concepts (The Java™ Tutorials > Learning the Java Language)

    I have also personally loved the Berkley univ's old (still perfectrly valid tho!) lectures, here is the start of one of their OOP lecture series:
    CS 61A Lecture 17: Object-Oriented Programming I - YouTube

    For a book, i'd go for the "Head first" series, but that's again just my preference. But as said, try to fiddle as much as possible with your own code and not just rely on passive learning. Don't be afraid of hard concepts and failing either. Just come and ask for a direction if needed.

    Best of luck with the learning!
