For the unit 2 assignment, you will develop a program that will simulate the rolling of a pair of dice. Your program must simulate rolling two dice and keep track of how many rolls are required before snake eyes are rolled (Note: “Snake Eyes” means that both dice show a value of 1). You will need to use a loop structure to repeatedly ‘roll the dice’. You will also need to make use of the if statement to determine if both die show a 1. You can use the example of an if statement below in your program and you can also read ahead to next week's lesson for more information on the if statement.

To roll the dice, you can use the following Java statement which generates a random number between 1 and 6 (to represent the six sides of the dice).

What the (int) in this case is doing is called a cast. The cast is a way to force java to convert data from one data type to another.

The subroutine (actually this is calling the class Math and the method random) Math.random() will return a number that is between 0 and 1. This number is a floating point number.

By multiplying it by the number 6 we will get a random number between 0 and 5. This number will be a floating point number and is likely to be a fraction meaning that it will have digits to the right of the decimal point.

What the cast or (int) in this case does is convert this number into an integer. As you recall from earlier discussions, this will truncate all the digits to the right of the decimal point. For example assume that the Math.random() subroutine returns the value of .523432. This value is then multiplied by 6 resulting in 3.14059 to this we add 1 resulting in 4.14059. The reason that we are adding a 1 is that we want a number between 1 and 6 starting at 1. By adding a 1 we know that the starting number will always be 1 or
