Write a simulator programme that flip a coin:
1. One thousand time then print out how many time you got tail and how many time you got head.

2. Continuously flipping coin until you find 1000 head count then print out how many time the coin has been flipped.

මේක හදාගන්න කවුරුහරි help එකක් දෙන්න​.

without UI
generate a random number in anyway you like. if the scale is low make is bit larger. then take the modulo 2 so you'll get either 1 or 0. nominate those as you like. then you have coin flipping.
then you can loop it and get the results

ඉතිං බන් Random class එක නැතුව කොහොමද අහඹු සිද්ධි ගන්නෙ. එහෙනම් Thread scheduler එක්ක පුලුවන් Synchronized method වලින්. ඒත් do-while loop එකෙන් කරන්න පුලුවන් විදියක් තිබුනත් මට නම් මේ වෙලාවෙ මතක් වෙන්නෙ නෑ මචන්.
