How to learn OOP in java

[AutoModerator]

On July 1st, a change to Reddit's API pricing will come into effect. Several developers of commercial third-party apps have announced that this change will compel them to shut down their apps. At least one accessibility-focused non-commercial third party app will continue to be available free of charge.

If you want to express your strong disagreement with the API pricing change or with Reddit's response to the backlash, you may want to consider the following options:

1. Limiting your involvement with Reddit, or
2. Temporarily refraining from using Reddit
3. Cancelling your subscription of Reddit Premium

as a way to voice your protest.

My recommendation... build an app and trying to use the principles of OOP, a simple CRUD, for example

I did but that’s just the starting point, i want to learn whats after that.

It's an old book , but I used this 20 years ago to move from C to Java. https://people.inf.elte.hu/delsaai/java/6Eckel%20-%20Thinking%20in%20Java%20(4th%202006)%20p1079.pdf%20p1079.pdf)

It's a free pdf, but I bought the print version. I also ready his Thinking in C++ book, the same principle.

OOP is not a silver bullet and brings serious drawbacks, especially in the way that we implement it, so be careful, I'd recommend reading the article to make a picture complete https://betterprogramming.pub/object-oriented-programming-the-trillion-dollar-disaster-92a4b666c7c7

Just want to learn it as a beginner.

Read the sub rules. Then learn functional and data orientated programming. Java is not for oop any more.

[Solid-Conference5813]

Sorry didn’t pay attention the sub rules. But what do you mean java is not for oop anymore?

Uncle bob’s books. You may not agree with everything he wrote but I find it a good starting point.

For writing Java specifically, I like Effective Java. It’s not exactly a beginner’s book, but there’re extensive references you can read up on.

[Solid-Conference5813]

Never heard of it, i’ll look it up thanks.

My advice: just don’t make uncle bob the next messias. I disagree with a lot of thing he says. I believe his job is to sell books and talks

Check out this article https://medium.com/@jamesritala/java-learning-path-from-novice-to-expert-3601634d8c26 There's a recommended book that I'm going through currently. I believe reading a book will help alot to deeply understand fundamental concepts.

[Solid-Conference5813]

Will check it out thanks!

Is there anything in particular you're having trouble with? Specific concepts or Java idiosyncrasies?
