我的双骰子模拟游戏程序需要帮助。掷骰子游戏的规则可以很容易地从 Google 找到。
这是我到目前为止所拥有的:
public class Craps {
//static class variables
static int Random, r1, r2, n;
//declare variables to be shared between methods here
public static Random r;
public static Scanner in;
static {
r = new Random();
in = new Scanner(System.in);
}
//this method returns a value between 2 and 12
//to stimulate the roll of the two dice
public static int roll() {
for (int i = 1; i<= 2; i++) {
int r= (int)(Math.random()*12);
System.out.println(Random);
}
return 0;
}
//this method implements the rules of the game for one round
//it calls the roll() method to stimulate throwing the dice
public static boolean round() {
boolean print = false;
//if roll 7 or 11 = win
int roll1 = roll();
if (print==true) System.out.print(roll1);
if (r1==7||r1==11) {
System.out.print("Win");
return true;
}
//if roll 2, 3, 12 = lose
else if (r1==2||r1==3||r1==12) {
System.out.print("Lost");
return false;
}
//if point equals same number as rolled the first time, win
else {
int r2=roll();
int point = roll1;
}
return false;
}
public static void main(String []args) {
//call the "round()" method n times in a loop
//to play n rounds
int n = 10;
for (int i = 1; i<=n; i++) {
boolean result = round();
}
boolean print;
//collect wins/losses at the end of rounds, output wins/n as percentage
for (int wins=0; wins<n; wins++) {
System.out.println("Winning percentage: " + (100 * wins / n) + "%");
}
}
}
总结我的问题是:
- 我是否表示了要生成的 2 到 12 之间的随机数，以刺激 roll() 方法中正确掷骰子？
- 如何编写 while 循环来重复 round() 方法中的 if-else 循环决策以允许额外的滚动？
- 如何创建变量“点”来继续滚动？
- 如何要求用户输入轮数“n”？
- 如何从命令行获取少量用户输入，作为在我的主方法中创建扫描程序的替代方法？
最佳答案
要获取命令行输入，请参阅 https://stackoverflow.com/questions/17501509/how-to-get-user-input/17501524#17501524
要先获得 100 的百分比倍数:
System.out.println("Winning percentage: " + (100 * wins / n) + "%");
否则，由于除以整数，您的结果将会四舍五入，请参阅 Dividing two integers in Java gives me 0 or 100?
