Design Patterns Revisited in Modern Java by Venkat Subramaniam

Design Patterns are common ways to solve problems that developers have discovered over time. They often fill the gaps between the language capabilities and the design goals. When languages mature, sometimes patterns become natural features of languages and blend in to the natural way of writing code instead of a special effort. Java has evolved significantly over the years. In this session we'll revisit some common design problems and see how patterns are realized to solve those problems with the modern capabilities in Java.

I have almost 20 years of coding experience, but this talk makes me feel i'm a rookie. Very inspiring!!!

This conference is a gem! I highly recommend watching it from start to finish.

[bhatsachin]

When you ask a scrum master to write a piece of code, he will write it like a story😀. Awesome presentation by Venkat.

[roshinivr]

This talk is pure awesomeness! That Decorator pattern with lambda was something I really needed in my current project. Thank you so much for explaining it so wonderfully. 😊

[prakashramachandran]

What a talk.. as usual very informative. All these topics are mindset shift when it comes to design

[kendlyduprince]

This is pure stand-up java
And I love ❤ it

[somethings]

This conference has inspired and influenced me on so many levels. From his overwhelming knowledge (which smells like thousands of experiences) to the elegant use of a text editor without the support of an ide

Spectacular

[Kidkromechan]

This was very helpful Venkat. Thank you. It's gonna take me a while to get comfortable with the patterns described here. The decorator pattern and the way you use consumer are very interesting. Also, now I finally understand Lazy loading a little better.

[toxema]

what a great "hand on" session. it is way better than a powerpoint presentation. thank you very much. ( NOT: Levent Kırca'dan Java dersi almadım da demem şu hayatta. )

[hutofrock]

Dr. Venkat is awesome! I always enjoy watching his presentations! 🙂

[rohitchakraborty]

This is the first educational video where I haven't felt sleepy

[omnipoten]

This guys is simply amazing. More I listen to him more I understand the programming.

[cedrics]

I thought I would never use the decorator pattern. But after seeing this new approach, who knows :)

[petergyt]

Subramaniam has a unique talent for explaining difficult subtleties with very simple examples.

[jamesschmames]

I love the opening. Just because you have the recipe doesn't mean the outcome is automatically good.

[ericm]

Found this extremely helpful to understand what and why we use design patterns ! Well explained

[thinhduonguc]

You're just amazing sir, especially for the one with low financial situation like me.

[VasileSurdu]

that Execute around method is really something cool to use. Also loved the decorator example. great talk
