there is a large part of the program missing, the output will be incorrect if you run
DiceSimulation.java.
I have declared all the variables. You need to add code to simulate rolling the dice
and keeping track of the doubles. Convert the algorithm below into Java code and place it in the main method after the variable declarations, but before the output statements. You will be using several control structures: a while loop and an if-else-if statement nested inside another if statement. Use the indenting of the algorithm to help you decide what is included in the loop, what is included in the if statement, and what is included in the nested if-else-if statement.
To roll the dice, use the nextInt method of the random number generator to generate an integer from 1 to 6.
Repeat while the number of dice rolls are less than the number of times the dice should be rolled.
Get the value of the first die by rolling the first die Get the value of the second die by rolling the second die If the value of the first die is the same as the value of the second die
If value of first die is 1 Increment the number of times snake eyes were rolled
Else if value of the first die is 2 Increment the number of times twos were rolled
Else if value of the first die is 3 Increment the number of times threes were rolled
Else if value of the first die is 4 Increment the number of times fours were rolled
Else if value of the first die is 5 Increment the number of times fives were rolled
Else if value of the first die is 6 Increment the number of times sixes were rolled
Increment the number of times the dice were rolled
4. Compile and run. You should get numbers that are somewhat close to 278 for each of the different pairs of doubles. Run it several times. You should get different results than the first time, but again it should be somewhat close to 278.
