      I don’t know what I did wrong, but the bug must be somewhere in HelloWorldExampleClassForTutorialBuilderFactory.HelloWorldExampleClassForTutorialBuilderFactory(StringBuilderFactory myHelloWorldExampleClassForTutorialStringBuilder, int numberOfTimesToDisplayHelloWorld)

    This thread reminds me that most “developers” are terrible and don’t take the time to understand the language.

    All of these Java developers you guys hate is the result of schools pushing out idiots. It’s not the language but rather the type of people you hire. These people will suck at writing in any language regardless of what order they try.

      Agreed, good tools can be used badly. Over the years I’ve written Java, C++, and PHP professionally, and I’ve seen excellent and horrible impls in each. Today, I mostly use Java and this thread is reminding me that I need to learn a new for-fun language.

          Kotlin won’t save your skin if the code you wrote should be performant but you layered it into a heap of abstract classes, interfaces, factories, etc and, realistically, no one else would use or expand on that

    I know the guy meant it as a joke but in my team I see the damage “academic” OOP/UML courses do to a programmer. In a library that’s supposed to be high-performance code in C++ and does stuff like solving certain PDEs and performing heavy Monte-Carlo simulations, the guys with OOP/UML background tend to abuse dynamic polymorphism (they put on a pikachu face when you show them that there’s also static polymorphism) and write a lot of bad code with lots of indirections and many of them aren’t aware of the fact that virtual functions and dynamic_cast’s have a price and an especially ugly one if you use them at every step of your iterative algorithm. They’re usually used to garbage collectors and when they switch to C++ they become paranoiac and abuse shared_ptr’s because it gives them peace of mind as the resource will be guaranteed to be freed when it’s not needed anymore and they don’t have to care about when that is the case, they obviously ignore that under the hood there are atomics when incrementing the ref counter (I removed the shared pointers of a dev who did this in our team and our code became twice as fast). Like the guy in the screenshot I certainly wouldn’t want to have someone in my team who was molded by Java and UML diagrams.

    I actually have a ton of professional Java experience and have done a lot of microcontroller stuff of late (for fun mainly) and if you go at doing software for ARM Cortex-M microcontrollers the Java way you’re going to end with overengineered bloatware.

    It’s however not a Java-only thing: most of those things have too little memory and processing resources for designing the whole software in a pure OO way, plus you’re pretty much coding directly on the low-level (with at most a thin Hardware Abstraction Layer between your code and direct register manipulation) so only ever having used high-level OO languages isn’t really good preparation for it, something which applies not only for people with only Java experience but also for those whose entire experience is with things like C#.Net as well as all smartphone frameworks and languages (Objective-C, Kotlin, Swift).

      I used to write a lot of performance-critical Java (oxymoron I know) for wearables, and one time I got a code reviewer who only did server-side Java, and the differences in our philosophies were staggering.

      He wanted me to convert all my code to functional style, using optionals and streams instead of simple null checks and array iterations. When explained that those things are slower and take more memory it was like I was speaking an alien language. He never even had to consider that code would be running on a system with limited RAM and CPU cycles, didn’t even understand how that was possible.
