Task #1 The while Loop 1. Copy the file DiceSimulation.java (see Code Listing 4.1) from the Student Files or as directed by your instructor. DiceSimulation.java is incomplete. Since there is a large part of the program missing, the output will be incorrect if you run it. 2. All the variables are declared. 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. 3. 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. 4. 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 5. 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. Task #2 Using Other Types of Loops 1. Change the while loop to a do-while loop. Compile and run. You should get the same results. 2. Change the do-while loop to a for loop. Compile and run. You should get the same results.
