Java 程序不像 python 程序那样工作，我不知道为什么

Question

我目前正在学习 Java，我对 Python 了解得很好，但我似乎无法让我的 Java 问题以与我的 Python 程序相同的方式工作。这是python程序：import random as randsuccesses = 0for x in range (1000):    stake = 100    bets = 0    while stake >0 and stake <200:        play = rand.randint(0,1)        bets +=1        if play == 0:            stake = stake -1        else:            stake = stake + 1    if stake == 200:        successes +=1    print ('stake = ', stake, 'bets made =', bets)print (successes/1000)print(bets/1000)当我运行它时，我得到这样的东西：stake =  0 bets made = 19832stake =  200 bets made = 5240stake =  200 bets made = 3156stake =  0 bets made = 10338stake =  200 bets made = 11198stake =  0 bets made = 6150stake =  200 bets made = 10934stake =  200 bets made = 11368stake =  0 bets made = 8724stake =  0 bets made = 17158stake =  200 bets made = 6158stake =  200 bets made = 7690stake =  200 bets made = 2170stake =  200 bets made = 12268stake =  0 bets made = 15878stake =  200 bets made = 16486stake =  0 bets made = 63960.5186.396现在这是我为我的 java 程序所做的事情 我被告知使用 Math.random() 和 Math.Round() 我认为这可能是我遇到问题的地方我不知道把 Math.Round 放在哪里()public class Gambler {    public static void main(String[] args){       double successes = 0;       for (int i = 0; i <1000;i++){           double stake = 100;           double bets = 0;           while(stake>0 && stake <200){               bets++;               if (Math.random()<0.5) stake ++;               else stake --;           if (stake==200) successes++;           System.out.println("stake = "+ stake + " bets made = " + bets);           }       System.out.println("average successes = " + successes/1000);       System.out.println("average bets = " + bets/1000);       }    }    }

Answer 1

public class Gambler {

    public static void main(String[] args){

        double successes = 0;

        for (int i = 0; i <1000;i++){

            double stake = 100;

            double bets = 0;

            double  play = Math.random();

            while(stake>0 && stake <200){

                bets++;

                if (play == 0) stake --;

                else stake ++;

            }

            if (stake==200) successes++;

            System.out.println("stake = "+ stake + " bets made = " + bets);

        }

        System.out.println("average successes = " + successes/1000);

        System.out.println("average bets = " + bets/1000);

    }

}
