Join Peggy Fisher for an in-depth discussion in this video Solution: Monte Carlo, part of Java Essential Training for Students.
- Welcome back, how did you make out…with that last challenge?…Well, I hope you had some success.…I'd like to go over my solution,…and as always remember, it might be different than yours.…I have my Monte Carlo simulation set up…to go through three different trials.…One, with a 100 attempts, one with a 1000,…and one with 10,000.…Let's take a look at the actual Monte Carlo code itself.…As you can see, I pass in the numTrials…to the method marbleSimulation.…On lines 28 and 29 I declare two static variables,…one to represent the blue marbles has a value of 1,…and a second variable to represent the white marbles…which will hold a value of 2.…
On lines 31 and 32 I have two variables,…double number record the number of successes,…the number of times all three marbles are the same color.…Double result will be the value…that takes the number of successes divided by the numTrials.…Starting on line 54 is my simulation loop.…I'm gonna scroll down a little bit.…Line 36 I add one to my total attempts,…then I declare on line 38 my bowl…
