这是一个家庭作业，我应该掷6个骰子，然后选择任意组合制作7并摒弃它们。 EX。 1,1,1,1,1,2。我的分数是0，因为我必须丢弃所有六个骰子。
起初我认为这是2个骰子的任意组合，但现在已被告知。我的代码现在反映了2个骰子，我不知道如何在不使用蛮力和写入每个可能的组合并检查它的情况下完成所有六个骰子。
private void calculateScore(){
//checks for 7's, calculates score if none, updates values
discardDieMessage = "Discard Dice. Combinations of die equals 7";
boolean noSevens = true;
//diceRoll is an array with 6 values
for(int i = 0; i<diceRoll.length;i++){
int temp = diceRoll[i];
for(int j = 0; j<diceRoll.length;j++){
if(temp + diceRoll[j] == 7){noSevens = false;}
}
}
if(noSevens){
playerScore[playerNumber] = 0;
for (int i = 0; i < diceRoll.length;i++) {
playerScore[playerNumber] += diceRoll[i];
}
playerScoreString = new String ("Your score is: " +
+ playerScore[playerNumber] +
"\nYou rolled: " + currentPlayerRolls + " time(s)");
update();
outputTextArea.setText(playerScoreString);
calculateButton.setDisable(true);
messageLabel.setText("");
}
else {
messageLabel.setText(discardDieMessage);
messageLabel.setTextFill(Paint.valueOf("red"));
}
}
UPDATE_1：这是我到目前为止的完整代码。这是一个7人的游戏，玩家掷6个骰子，他们必须丢弃等于7 EX。{3,2,1,1}的骰子而其他两个骰子是{6,6}，所以其余的骰子不再等于7.
