Programming Language

Programming Language এর মধ্যে সবচেয়ে সোজা হল Java programming Language.
এটা আমি আগে জানতাম না।
Java programming Language.শিখার পর আমি এটা বুঝতে পেরেছি।
Now I am so Happy.
বি.দ্র: দূরের শিক্ষাথীদের জন্য আমি Java programming Language এর উপর বিশেষ Virtual training এর ব্যবস্থা করেছি।
