    I have a Java test this Monday and yesterday I broke down and cried myself to sleep because I was so frustrated and confused with my lectures, now things seem way, way simpler for me. I understood in 15 minutes what I have tried to understand a whole semester. Thank you thank you thank you!

    You've explained static / not static in the most clear concise way where it finally clicked for me. This whole entire video was well said. I had low expectations when I saw 15 minutes but you really did an extremely good job.

    I'm a beginner programmer and I've been learning python actually for about 3 weeks now, but I am interested in learning about Java too. Gotta say compared to a simple
    print("Hello World") in python, the way to print hello world in java seemed way more complicated. this video helped me to have a better understanding of how python scripts work.

    To be honest, in my 3 years of experience, I hadn't come across a very straightforward and understandable explanation of Static vs Non-Static. Whenever people try to explain it, they tend to prioritize either time or quality, sacrificing one over the other. But in this case, you managed to provide a nice explanation without compromising on either time or quality. Great job! ( I was really struggling to explain this to a friend)

    My man, I have been on a rollercoaster of a career, and long story short I need Java to get a position at a company I worked for previously, but was unfortunately laid off due to lack of projects for me to be on as a Manual QA tester. Finances have been tough and the faster I can learn, the faster I can get my life back on track as an automation engineer and you just made sense of 2 months of scrambling trying to fins out how to use this language. Hell, until this video, I was still confused on what exactly a class is, and you just flat made sense of it for me. Definitely going to check out your courses, you are the MAN!

    9:00 protip: never pass the constant into the equals method, always pass the class into the equals of the constant. E.g "John".equals(name). Why? If name is null you get a NullPointerException in the first case, but it is a safe statement on the second.

You definitely made some of it make sense…like I get the feel of what is actually going on now. Versus looking at a bunch of codes just doing what I can to follow along. I was like why I am even writing this, why does it have to go here, what is one line doing for the other, etc.. I was feeling like I needed an “Intro to Introduction to Java” class 🤣.

I’ve played with Python, JavaScript, HTML, & CSS on my own but never Java. I finally start my coding classes next month and I’m terrified, but this video made me a little less so. I have imposter syndrome & feel stupid for pursuing programming, but I know that I want it bad and that I’m willing to work hard for it.

    🎯 Key Takeaways for quick navigation:
    00:00 🧠 *Struggling with Java is common; feeling overwhelmed is normal. Learning takes time and practice.*
    00:44 🛠️ *Installing an IDE (Integrated Development Environment) like Eclipse simplifies Java coding, similar to how Microsoft Word assists in writing documents.*
    01:41 📝 *Creating Java programs involves writing code within classes and methods, where the main method serves as the starting point for execution.*
    02:23 💡 *Variables in Java store data and have types (e.g., int, double, char) and values, ending statements with semicolons.*
    03:08 🔄 *Java supports different variable types, such as integers (int), decimals (double), and characters (char), allowing for operations like multiplication.*
    04:20 🧱 *Primitive types in Java (e.g., int, double) are foundational, while other types, like strings, are built upon them.*
    05:03 🛠️ *IDEs like Eclipse provide features to explore available methods and their descriptions, facilitating code development.*
    05:58 🔄 *Methods in Java encapsulate code for reuse and organization, accepting parameters and optionally returning values.*
    07:09 🤖 *Conditional statements in Java (if-else) enable decision-making based on conditions, allowing for branching logic.*
    09:42 🔁 *Loops (like for loops) in Java automate repetitive tasks by iterating over code a specified number of times.*
    11:20 🧱 *Object-oriented programming in Java involves creating and using classes to instantiate objects with attributes and methods.*
    12:56 🛠️ *Static methods in Java can be called directly from the class without creating an object instance, while non-static methods require object instantiation.*
    14:34 🎓 *Learning Java is a process, and resources like courses can provide in-depth understanding, but practice and experimentation are key to mastering it.*
