I don't hate design patterns exactly but I hate the way those architects boast about the design patterns in every meeting, as they know nothing except those & make the life of actual developers a hell...
This content can alone make a great book for a Java developer.😊

The refactoring at 16:18. That was just like magic!!!
EXACTLY MY OPINION ABOUT DESIGN PATTERNS! Mr Subramaniam make a good point!
This lecture is as funny as any sitcom. 😀😀😀 Nice delivery.
There was not a single pause, great talk. Along with code samples, please share the shortcuts as well. thanks Venkat
Thank you very much sir. I learned a lot. My perspective towards the design pattern is changed.
Design patterns only exist because OOP was an insufficient tool for communication and expression.
Lambdas are like Beer. We all started with it disliking how it tastes.
THIS IS A PERFECT ANALOGY HAHAHAHA
The mailer example is very interesting.
great talk, impressive examples, thank you Venkat
what was it that he did at 8:01 ? Making a tick on the todo list in the editor. How to do that ?
That is exactly what I'm trying to figure out right this second. Did you ever find an answer?
On VSCode it's ToDo+, default toggle is alt+d for done. Todo+ has plugins for most editors.
The intro is fabulous!
Don't know if he is really talented or I'm just very stupid.
Completely makes sense after that intial thread example.. I'm like how dumb..
I was thinking the same :) about me .
Wow this is how programming solve your daily life
Shouldnt the send have Supplier of Mailer , instead of Consumer ? So that clients can create concrete Mailers outside execute and pass those?
how does var works in java virtual proxy example lazy using Supplier
Welcome to the era of functional programming. Next stop is realisation that you don't need OO at all.
I will diaagree
already expected good stuffs from him even before watching the vid lol
These are very useful. Is there like a book for this?
There is a book called "functional programming in Java". All these topics are detailed explained in that book. Book author is same Venkat
Great talk, only the Q and A was a bit scary, better not ask anything :D
Awesome
till 17:04
Indian Brahmins are so intelligent he is just an example of it .. by the way Which IDE he uses as it compiles and shows value in real time ?
