In the logic you are incrementing the leftpointer and decrementing the right pointer, then doing a swap. There is no logic that determines if a swap is actually needed such as when the two pointers meet. Do you just leave it this way and let it swap an element with itself as being less effort than doing the logical test? I don't understand how randomly choosing an element from the array is any better than just using the last element of the array. If you start with an array of random numbers then you have just as much chance of having a good value of the pivot already at the last element of the array as you do choosing another element at random.

Hello John, and welcome back! I would like to ask you a question if you have the time, or maybe you could make a video about this topic. When I create a project and include external libraries, I want to package the final project into a single JAR file. However, what happens is that I end up with a "lib" folder next to the JAR file, and it doesn't work without that folder. Thank you again!

Java destroyed my career. I just could never transition. Over 28 years of C, C++, assembly, Lisp, and a bunch of others... encountering Java was like hitting an impenetrable brick wall at high speed. I loath it. I loath everything about the language, tools, and ecosystem. It's total crap. Yeah, I kniw a bunch of people love it... I don't, and I left the industry because of it. Your video was good. I liked it, but Java sucks.

Congratulations- after long time it You nailed it our 10th level of recruitment stage, but sorry we cannot hire you John Brown for a junior dev position because our employee hashmap only allows a replace - so there as it we already have another guy with a same name a senior dev John Brown - we dont want to replace him - good luck finding another company.

I'd like to see you more often. Do you fancy solving small programming tasks like adventofcode? Few KZbinrs do these programming tasks in Java, and none of them solve them in an understandable way. Doing the easy ones (usually tasks 1 to 4(5)) would be a great resource for learning basic concepts in a programming language.

Hello John, been watching your videos for a while! In addition to Spring related videos others have already suggested, may I also suggest you make a video about the Stream API and the Collectors class?

There are two issues that make Java difficult in my opinion. Firstly, there is too much redundancy. You try to find out how to do something and there so many ways to do it. Being a novice, you have no way of determining which options are best practice or better. Secondly, Maven and Gradle lack simplicity.
