The game of Pig is a sample two player dice game in which the first player to
reach 100 or more points wins. Players take turns. On each turn a player rolls a
six-sided die. After each roll:
. If the player rolls a 1, then the player gets no new points and it becomes the
other player's turn.
. If the player rolls 2 through 6, then he can either:
. ROLL AGAIN or
. HOLD. At this point the sum of all rolls is added to the player's score
and it becomes other player's turn.
Write a program that plays the gmae of Pig, where one player is a human and the
other is the computer. When it is the human's turn, the program should show the
score of both players and the previous roll. Allow the human to input "r" to roll
again or "h" to hold.
The computer program should play according to following rule:
. Keep rolling when it is the computer's turn until it has accumulated 20 or
more points, then hold. If the computer wins or rolls a 1, then the turn ends
immediately.
Allow the human to roll first. The following line of code can be used to generate
a randon number between 1 and 6 that can correspond to the dice roll:
int diceroll = (int) (Math.random() * 6) + 1;
