Vedios are good,with detailed explanation. I would suggest to make wordings corrections,like in map you said new record is repalced with old record when you add new entry with duplicate key and different value.But actually it is old record is replaced with new record.

Somewhere in between, 26-27 min, you said, HashMap is an Interface and Entry is sub-interface of HashMap. But isn't HashMap a class ? It is not an Interface and Entry is an interface that implements Map interface not HashMap. Could you please clarify for your students ?

Hello Hope you see this comment ..... I am new to automation testing and just have switched from development to Automation Testing..... I know my question might be stupid and baseless but as a fresher in Automation/SDET I always wonder about this as I want to continue growing in the automation field and which is what motivated me to switch from development....But this one question always keeps me down and bothers me a lot in my path....I dont know why but my developer friends always tell me "You should be in development as the focus more now is shifting towards developer doing everything rather than having a separate qa automation sdet ....Developer also does some automation in some companies .....This is what my friends tell me and which bothers me a lot .....I igonre them But as a human having little experience in automation what is your take on this? I know this might be a stupid question that only a fresher can think of but my friends always warn me that future is more towards the developer doing everything and no separate tester will be required.....I 100 percent dont want this to be true as I love automation but one time I want to listen to your thoughts on this and clear my stupid doubt(even if this question pisses you off) You are my teacher so I ask you as a student the reality of this (I have gone anonymous because I am ashamed by my own question ) If you read this please reply ......🙏🏻

Your friends could be right because with the rise of Agile methodology and the extensive skills a technical QA possesses, there would be little difference between QA and Dev down the line. It is trending that way. With that said, QA industry is not disappearing abruptly. In fact, IT job market is so volatile that today's dev skills won't be sufficient with the rise of AI. So, don't panic. Whichever industry you like, grow in it.
