    If you’re new to programming but want a career in tech, I HIGHLY RECOMMEND applying to one of Springboard’s online coding bootcamps (use code ALEXLEE for $1,000 off): bit.ly/3HX970h

    I have to say, as a beginner, the way you break things down, give examples, and the layout of your videos that show what you're typing and even the shortcuts, are so very beneficial. Thank you for all of the awesome tutorials.

      Taking time to dissect the code step by step has always been challenging yet rewarding. With comprehending the concepts, you'll quickly pick up the rest of whatever area you're studying. I recommend locating broken code on the internet and fix it up as a random challenge.

    your tutorial videos have been exponentially helpful as i just enrolled in a computer science degree and know nothing about programming. I will definitely recommend your channel as it is the most clear cut, example laced, description on what the hell i'm doing, or trying to. I appreciate your help.

The links on the description are more helpful than so many other coding videos on youtube :D. I just liked the links and wanted to thank you.

    I like your short and concise style of explaining. Sure you dont mention every detail (which is impossible anyways)and there are some important things left unsaid, but if you just want the basic information and then work with it yourself, which I think is the only way to truly learn programming, this is perfect.

    i got selected for a new java training through a requalification program by the employment exchange. though my trainers at the uni are proficient the fact that i'm an english native learning java first time in a different language at speed that does not afford practice had left me seriously doubting my cognitive abilities. it's in your videos that I actually feel that java is really easy and not such a 7 headed monster as I was first inclined to believe in while I was seriously contemplating jumping out of the ship if not for a colleague who helps and ofcourse your lovely easy to understand videos .

    The video was great on its own, and I appreciate the lesson. That said, the subtle subscription plug(where you worked a subscription reference into the lesson by saying that array lists are probably how they handle subscriptions) was fairly brilliant and got a chuckle out of me. Whether it was done consciously or not, its what got me to subscribe, lol. Thanks again
