Java Video Tutorial 19

In this part of my Java Video Tutorial, I cover Java Regular Expressions. You use regular expressions when you want to search for data. You then use codes to define what that data looks like. It is much easier than you can imagine.

of all java topics, from object oriented to everything else, this is the only subject I can't understand through reading documents online / books, your video helped me a lot understanding it :) Just leaving this comment to let you know :)

I'm always happy to help if I can. I consider answering questions to be my highest priority. I consider it essential to help people learn.

Hello sir, i'm currently downloading all your java video tutorial series, thanks for your great work. You have added a lot of value to my life through your free tutorials so the list i can do for now is say THANK YOU, you are so awesome and God bless you.

I'm very happy I'm able to help :) There are 2 main obstacles to learning how to program an OOP language. 1. To understand the OOP jargon 2. To understand how to turn an idea into a bunch of objects. I cover The jargon pretty well in the first 2 videos in my design patterns tutorial. I cover how to turn ideas into programs in the first 2 parts of my Object Oriented Design tutorial. The OOD tutorial may help a ton. The idea is to understand the process and not necessarily all of the code

Such comments are so popular now so ... "Who's watching in November 2015??" ... but now for real. Man this is the best Regex tutorial for Java out there. May be a bit hard to understand for someone who sees Regex first time ... but if you have some vague idea about it (like me) then it's VERY helpful. I feel like I finally understood how it works. I wish there were some life chats with you to ask questions :-)

Cheers!

There are a ton of programmers that know 30% of 8 languages, but there are very few that know 100% of one. I always preferred to be a 100% guy. I can accomplish pretty much anything knowing just java and C++. I devoted myself to them. C++ when I was little and now Java for the last 15 years. Stick with java until you are 100%

I love your tutorials . they are so welcoming and your videos don't just teach people but they help me understand the concepts. And personally i begin learn things better when they make sense to me and I believe i can say that on behalf of many. Thank you for what you do.

[derekbanas]

Stick with it. If you get the code and take notes you'll be able to proceed at your own speed. That seems to work for everyone. Play around with the different codes and the phone number and it will make sense

You're a lifesaver man. I just can't thank you enough for your videos.

[derekbanas]

I have a ton and plan on covering everything there is to know about Java. I'm glad you like them :)

[derekbanas]

The kind words are definitely enough. They make me very happy. I have no need for money when people are so nice to me. Thanks for taking the time to write out your nice thoughts :)

[derekbanas]

You're very welcome :) I have many regex tutorials and because regex are the same for every language you can watch them and then use them as you like. Type regular expressions and regex on my YouTube channel for a ton on the subject

[ridvanusa]

I was trying to get a grasp of what regular expressions are. I read some documents but I got lost. this is video shows exactly what I wanted to know. very good explanation with a clear voice, thank you

[derekbanas]

You're very welcome :) I'm glad you enjoyed it. I try to pack more into a tutorial then anyone else

[anasyum]

it's been some time since i've been programming with Java, i've never heard of regular expressions ... don't know why, they are so handy and useful, but the way you explain it is Top ... i'm now watching all your videos... thank you sir ! (from Belgium)

[derekbanas]

Regular expressions are nearly identical irregardless of the language. If you can learn Java over Python, Java is much more powerful in my opinion. Python is definitely easier to learn, but it eventually will limit you.

Thank you for tutorial, Derek!
 Perl: $_ = "A b c"; print "Found b" if m/b/;
Java: two classes, three pages of code.
What a language. Redundant, slow, insecure and used everywhere. How come it became so popular?

[utkuhangol]

Even though it's been over 7 years since you uploaded this serie of Java Tutorial it helps me a lot. Love your work man.

[derekbanas]

Sometimes the most efficient way to grab information is through repeated use of different regex until you get exactly what you need. Just think about how you'd find this information on your own, write out the steps and then program them

[derekbanas]

You're very welcome. Thanks for watching :)
