Morris' Blog 我在摸索我存在的意義、生命的意義、內涵及價值。 沒有真正神手般的厲害，套用模式是大部分的情況。 沒那麼厲害的我存在的意義為何，襯托出神的存在？ 有時候不能怪別人不給我機會，我已經開始省思， 為什麼我沒有給別人機會的原因，而是全要靠別人。 有時候我認為我與眾不同，那是因為我做不到很多人能辦到的事情。 我聽不到、玩不起來、說得不夠明瞭、理解得不夠多， 我缺少的語文能力，就是一切一切無能的判定。 為此，我不曉得能做些對別人有幫助的事情。 我知道我自己是個不服輸的性格，但現在我不得不認輸。 我沒有能力，因此我必須認輸。 我到底來這世界作什麼？處處充滿不確定性， 而我總是無法出類拔萃，想當個一般人似乎也回不了頭了。 越強大的挑戰需要越強力的支持，而我的支持是什麼？ 最近嘗試與人談話，但都是失敗的結局，沒人能接受， 不需要言語，不需要溝通，一切所想都表達不出來。

/**

 * @author Shiang-Yun Yang
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;

                System.out.println("You win ! Your score is " + human.getScore() + " .");
