Answer:
As per regulations, I can only answer the code in while loop.
Explanation:
Code in JAVA is given below for while loop
Please read all the comments for better understanding of the code.
Every step is explained well in the code.
Note class name is DiceSimulation.
Code in JAVA (Using while loop)::
import java.util.Random; // Needed for the Random class
/**
This class simulates rolling a pair of dice 10,000 times and counts the number of times doubles of are rolled for each different pair of doubles.
*/
public class DiceSimulation
{
public static void main(String[] args)
{
final int NUMBER = 10000; // Number of dice rolls
// A random number generator used in
// simulating the rolling of dice Random generator = new Random();
int die1Value; // Value of the first die
int die2Value; // Value of the second die
int count = 0; // Total number of dice rolls
int snakeEyes = 0; // Number of snake eyes rolls
int twos = 0; // Number of double two rolls
int threes = 0; // Number of double three rolls
int fours = 0; // Number of double four rolls
int fives = 0; // Number of double five rolls
int sixes = 0; // Number of double six rolls
// TASK #1 Enter your code for the algorithm here
/**
* Following while loop will run until count < Number.
*/
while(count<NUMBER){
/**
* To generate random number in range 1 to 6,
* I have declared two integer variables named min and max
* and initialized to 1 and 6 respectively.
*/
int min=1,max=6;

Random rand=new Random();

die1Value = rand.nextInt((max - min) + 1) + min;
die2Value = rand.nextInt((max - min) + 1) + min;
/**
* Now we are interested in cases where there is double i.e
* Both random generated numbers in die1Value and die2Value are same.
*/
if(die1Value==die2Value){
/**
* Now there are 6 possibilities. They are shown in Nested IF-ELSE-IF statements.
* As both values are same, I have taken die1Value to check if it is 1,2,3,4,5 or 6.
*/
if(die1Value==1){
/**
* If die1Value is 1 then we increment snakeEyes by 1.
* Similarly for others too we do the same.
*/
snakeEyes++;
}else if(die1Value==2){

}
}
/**
* In each iteration we increment count by 1.
*/
count++;
}//While loop ends here.
// Display the results
System.out.println ("You rolled snake eyes " + snakeEyes + " out of " + count + " rolls.");

}//main ends
}//class ends
