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"; } }
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
