Simple Java probablitity program?

[nothing4me]

Could anyone type up a simple probability program?

For example...
a has a chance of being picked .44
b has .22
c has .30
d has .04
All added equals 1.00

So, how would I print a string of 50 chars, a through d, with those probabilities/chances?

yes, you. please don't ask others to do your homework.

You could create an array of 100 chars and place x 'a' chars in it, y 'b' chars in it, etc... then use the util Random class to randomly select a char and use it.

I already thought of that... I'm sure there's a much more less barbarous way, so I'm asking here. :(

Nothing barbarous about it. If it works, use it. If it doesn't don't.

Oh and cross-posting can frustrate anyone who tries to help you only to find out later that the same answer was given hours ago in a cross-posted thread. No one likes wasting their time, especially a volunteer. The polite thing to do would be to not do this, but if you feel that you absolutely must, to at least provide links in both cross-posts to each other.

If anyone can suggest a more efficient way, please let me know!

And thanks, Fubarable. But, I need efficiency. :(

[Fubarable]

Then tell me how is it inefficient? Have you run it through a profiler and found it to have bottlenecks? What are the bottlenecks then? Just what do you suppose is faster than calling a random method followed by a quick lookup in an array?

Interesting that you chose to concentrate on your little flame war in the other forum, and decided to ignore any constructive discussion in this forum.
