hey /sci/
so I'm trying to teach myself Java and I think I've started off okay but I seem to have come to a dilemma.
I want a code that will choose a random double random_wanted and if that double is not .99999999, I want it to repeat until it attains .99999999.
So far here's my code, I just don't have enough knowledge about this to actually know what to do.

import java.io.*;
import java.util.Random;
public class Tester
{
public static int main(String args[])
{
double random_wanted=Math.random();

if(random_wanted<.999999999999999)
{


tl;dr a person who's new at java is looking for some coding help

Please don't do this.

Okay, lots of gripe here...

How about this, why are you looking for the number 0.9999_whatever? That would help the thread understand your intent.

(Also, you might be there a looooooong time.)

I'm looking fto see how many times the random method has to be used until such number appears. Kind of like me seeing how many times I have to roll a die for me to get a 1.

You just need a while loop or for loop there, and a lot of time. Might want to start with fewer 9s to test it.
