Java实现根据概率中奖率怎么算

#1、我们可以通过随机数0~1来判断是否中将

import java.util.Random;

public class Lottery {
    public static void main(String[] args) {
        // 中奖概率，假设中奖概率为20%
        double winningProbability = 0.2;
        
        // 生成随机数
        Random random = new Random();
        
        // 生成0到1之间的随机数，如果随机数小于中奖概率，则认为中奖
        double randomNumber = random.nextDouble();
        
        if (randomNumber < winningProbability) {
            System.out.println("Congratulations! You win the lottery!");
        } else {
            System.out.println("Sorry, you didn't win this time.");
        }
    }
}
