Who cares about SOLID principle or Single Responsibility? Just do whatever makes sense to you. Most of the times, whatever makes sense to you is a design pattern.
6:55 the code format is not nice: why is there always an empty line at the beginning of each method body? Sometimes, there's no empty line between methods.
12:59 The string pool sizes vary in different java versions, jvm implementations and are configurable. So, IMO, in String str = "foo" we don't know if "foo" will go to the pool or not. That means we shouldn't care about the string pool.
41:00 IMO, it's not a memory leak as I can still use it with Test.noList. IMO, memory leak is the memory that cannot be GCed but we cannot use it because we don't have any variable pointing to it. This is the only example of memory leak that I know of: you have a web app, every request will be served by a thread; then you write some data into the ThreadLocal of that thread. So, the thread can be terminated and cannot be used for another request because it still has data and if we're not in that thread anymore, there's no way to use that thread's ThreadLocal.
44:19 it's 2024, is there any reason to use .wait(), .notify(), synchronized ... (all of them destroy the purpose of virtual threads)?
45:00 does "implements Serializable" help with anything? Does it make an object serializable if that object has something not serializable? Does the absence of "implements Serializable" make an object not serializable even when all the properties of that object are serializable? If the answers are NO, then why do you want to write it?

As always, great content mate.

I'm not sure if you have any plans but it'll be awesome to start a leetcode series for Java.

Anyways, thank you for always uploading great content, keep up the good work 👍
