It's well known both to gamblers and to people with some basic knowledge of probability theory that a score of 7 is far more likely than a score of 2 or 12 when a pair of dice is tossed. To investigate this from a slightly different point of view, write a two class program - DiceTally and DiceTallyDriver (includes main) which does the following: 

Your program should read in a target tally value, say 15, from a JOptionPane display (your code should be able to handle any positive value). Then your program should throw a pair of dice repeatedly until all dice outcome values 2 through 12 have occurred at least the tally value number of times. 

Finally, your program should report:

a) the number of times each dice value outcome has turned up; and 
b) the total number of tosses made. 

Some suggestions. Feel free to cannibalize the SimpleDice class from chapter 4 to obtain code for throwing dice. Also, it's useful to write a method you might call minVal, which calculates the smallest value at any time from among the tallied dice value outcomes 2-3-...-11-12. For example in the sample run below minVal would report 15. Clearly your experiment should end when minVal reaches the target value.

A sample run is below (your JOptionPane display need not look exactly like this). Notice that the 651st toss value must have been a 2. Why? If it hadn't been a 2, then the "2" entry in the tally would have been 15 after toss number 650 (and all of the other tally values would have also exceeded 15). Thus the target value would have been reached already for all possible outcomes by toss 650, and so there would not have been a 651st toss.
