I pay 9k for uni when this guy is better than all my lecturers combined

Thanks for doing this stuff. I'm an old java programmer, having help usher in Java back in the mid 90s. I've retired and now want to just code for fun and your code examples are a wonderful resource.

Really enjoying your videos! The way in which you break down these concepts is concise, and yields high value for someone studying java for the first time

[amiyoshikawa]

Thank you for this! Your explanations are so clear and concise! I've been struggling on an assignment all week and this video helped me a ton. Appreciate you!

The second video I watched from your channel so far and its been very straightforward and useful for me. Especially when I'm not very familiar with the concepts. Thanks :)

This guy's playlist beats two semesters' worth of university classes.

Rarely do you find entertaining content that's pure education

[mikewinchel]

Great video, a "for each" loop is also a good option to display all the elements in an array

for(String f : food)
{
System.out.println(f);
}

Aún sin hablar inglés, puedo entender todo sin usar un traductor. Es tan didáctico y claro al explicar, es uno de los mejores, sino el mejor profesor de Java que hay, no solo en YouTube sino sino de otras plataformas que también probé. AHORA EN INGLÉS. NOW IN ENGLISH. <<<---->>> Even without speaking English, I can understand everything without using a translator. He is so didactic and clear when explaining, he is one of the best, if not the best Java teacher out there, not only on YouTube but from other platforms that I also tried.

[kucor]

are there any real life examples on where/when we use each of those methods? I get all of this but still have no idea what are they used for. Or it's too early for that?
