It might be difficult if you hear it without any prior knowledge, but it seems to be very helpful if you briefly go through it and practice.

This lecture is a great lecture for those who have studied Java to some extent and are getting into lambda expressions, rather than those who are just starting out with Java. I didn't know how to use it while doing a project, and I was using stream and lambda expressions for the first time, so I couldn't understand it no matter how much I looked it up, and I was frustrated, but I finally found out about this sweet lecture that can be finished in just one hour... I watched it, and it hasn't been that long since the lecture came out. This is my first time leaving a review while listening to the lecture. The reason I didn't understand lambda expressions and streams is because I didn't understand the process for the code to change like this, but I understood it so well because you received an interface as a parameter, inherited it, and showed the result. Thank you.

I think everyone has a frequency that suits them best~

Please make sure to check if the style suits you through the preview video before enrolling.

๐Ÿ’ฆPeople for whom this lecture is less likely to be helpful

I have never learned Java

never done so before~

Other programming languages too

absolutely no experience~

A skill does not become yours just by hearing it once.

You will definitely need time to organize and review everything again!

See you again then~ ๐Ÿš€

๐Ÿ”น What are the reference notes?

  • The practice environment is Java 8+.

  • I recommend learning on a PC if possible.
