⌘⌘⌘⌘ ☢︎ Welcome to my channel ☢︎ ⌘⌘⌘⌘

I’ve started this channel because I love teaching. And also for learning by sharing and teaching the knowledge that I have. I really enjoy teaching programming and Android specially and I love it. So thats why, I’ve started this channel. I learn everything in detail. I search a lot and I mean a lot to get better and full understanding why some thing is happening the way it is. And I teach the same way, I don’t share any knowledge unless I don’t know what and why its happening and I search a lot before making any video. When I think I have detailed knowledge of the topic, then I make video.
So any suggestion or feedback is highly appreciated. Thanks

Sir referral system and earning app kaise banate hai

[tharunkumar]

Can you please explain this one..
Which I am going to talk about are seperate patterns you have created for caps, smalls, numbers and special characters...
In the password patterns for capitals, smalls, digits and special characters, you have passed length as zero.. That means the number of those respective characters (capitals, smalls...) can be zero or more than zero.. Shouldn't it be one?? Because minimum one character(all those capitals, smalls, numbers and special characters) is required in the password.. But how zero length is working fine in code??
