your contribution for learning java can not be described in a word. Thank you buddy. I am learning java watching your tutorials easily. May allah give you more power of knowledge so that you can make more tutorials on computer science as much as you can. At last i want to say you " Really you are awesome". . .

এই কাজ প্রোগ্রামিং এর মাধ্যমে করতে পারব সেটা আগে জানতাম না। thanks, You are my inspiration in programming.

The best tutor in Bangla tutorial so far. Keep up the good work, sir.

[ShakilAhmed-wkvh]

Vai, Apnar video onek valoo, Onek kisu shikte parlam, ami o video banai but atoo valo korte pari nai, Ami just Shekar jonno video banai, Ate kore amar o shika hoi abar onno k o bola hoi, Vai best of luck. Thank you so much. Amader jonno, Apnake onek kosto korte hoyese. Thank you.

Thank you sir.And really really appreciate your video

[yeakub_sadlil]

Masha'Allah brother. It was excellent as you have explained it with easy example.

[delwarmahdi]

Very nice for beginner students of Java, like me,
