Java程序抛硬币
假设我们有一个硬币和10个机会。在这里，我们将首先初始化头，尾和机会的值-
int heads = 0; int tails = 0; int chances = 10;
现在，我们将使用Random对象获得head和tail值-
for (int i = 1; i<= chances; i++) {
if (t.chanceFunc().equals("tails")) {
tails++;
} else {
heads++;
}
}上面的函数chanceFunc()具有使用nextInt()方法获取下一个随机值的Random类。检查条件并返回头和尾的值-
public String chanceFunc() {
Random r = new Random();
int chance = r.nextInt(2);
if (chance == 1) {
return"tails";
} else {
return"heads";
}
}示例
import java.util.Random;
class Toss {
public String chanceFunc() {
Random r = new Random();
int chance = r.nextInt(2);
if (chance == 1) {
return"tails";
} else {
return"heads";
}
}
}
public class Demo {
public static void main(String[] args) {
Toss t = new Toss();
int heads = 0;
int tails = 0;
int chances = 10;
for (int i = 1; i<= chances; i++) {
if (t.chanceFunc().equals("tails")) {
tails++;
} else {
heads++;
}
}
System.out.println("Chances = " + chances);
System.out.println("Heads: " + heads);
System.out.println("Tails: " + tails);
}
}输出结果
Chances = 10 Heads: 3 Tails: 7
让我们再次运行程序-
Chances = 10 Heads: 4 Tails: 6
