This is a simulation of rolling dice. We will roll 10,000 times in our program. The theoretical

probability of rolling doubles of a specific number is 1 out of 36 or approximately 278 out of

10,000 times that you roll the pair of dice. Since this is a simulation, the numbers will vary a

little each time you run it. We will start with a while loop, then use the same program, changing

the while loop to a do-while loop, and then a for loop.

We will be introduced to file input and output. We will read a file, line by line, converting each

line into a number. We will then use the numbers to calculate the mean and standard deviation.

Task #1 Loops

1. Copy the file DiceSimulation.java into NetBeans or other Java IDE tools.

2. The double roll of 1s and 2s are given in the code. You can run the program to get a

result like:

3. You follow the style to code for double roll value for 3 – 6 so all the doubles should be

around 278.

4. Change the while loop to do-while loop and run the program. Result should be similar.

5. Change the while loop to a for loop and run the program. Result should be similar.

Task #2 File Input and Output

1. Copy the files StatsDemo.java into NetBeans or other Java IDE tools.

2. Read “FilePath.doc” to know where to put the Numbers.txt.

3. The file input and output part is coded. Try to read through the code and understand the

program.
