Question

Please fllll this out thank you

/**
*

* Creates a six-sided die and rolls it 20 times. It outputs the face values and also
* the number of times the die lands on 6.
*
* Creates 2 eight-sided dice and rolls the pair 10 times. It prints out a sequence
* of pairs representing the face values as well as the number of doubles.
*
* Allows the user to repeat the above steps as often as (s)he wishes.

// set up a loop that iterates exactly 20 times, and each time through the loop do the following:

// value to keep track of 6s, and check to see if you have printed 4 numbers already, if yes,
// then advance to the next line.

System.out.println("Rolling a 6-sided die 20 times:" );

// create two eight-sided dice
// create two 'Die' objects and then use the method 'setSides' with each object to set its number of sides to 8

// throw a pair of eight-sided dice 10 times, output the face values of each throw as a pair
// and also the number of doubles (both dice land on the same face value)
// set up a loop that iterates exactly 10 times, and each time through the loop do the following:
// roll both die by calling the method 'roll' twice; print out their face values as a pair;
// and check to see if both face values are the same, if yes, keep track of it.

// add a do-while loop to repeat the above code as often as the user wishes
