java - Java 中无法访问的代码

Question

我不明白“无法​​访问的代码”是什么意思？

在我的代码的最后一行doubleprobabilityOfWin=wins/(wins+loses);它表示无法访问代码。

import java.util.Random;

 public class CrapsGame {
    public static final int GAMES = 9999;

public static void main(String[] args) {
    Random randomGenerator1 = new Random();
    Random randomGenerator2 = new Random();
    Random randomGenerator3 = new Random();
    Random randomGenerator4 = new Random();

    int dice1 = randomGenerator1.nextInt(6) + 1;
    int dice2 = randomGenerator2.nextInt(6) + 1;

    int comeoutSum = dice1 + dice2;
    int point = 0;

    // The comeout roll

    if (comeoutSum == 7 || comeoutSum == 12)
        System.out.println("wins");
    else if ( comeoutSum == 2 || comeoutSum == 3 || comeoutSum == 12)
        System.out.println("loses");
    else
         point = comeoutSum;

    int wins = 0;
    int loses = 0;


    while(GAMES <= 9999)
    {
        dice1 = randomGenerator3.nextInt(6) + 1;
        dice2 = randomGenerator4.nextInt(6) + 1;
        int sum = dice1 + dice2;

        if (sum == point)
            wins++;
        else if (sum == 7)
            loses++;
    }

    double probabilityOfWin = wins / (wins + loses);


}

}

Answer 1

这里循环:

while(GAMES <= 9999)
{
    ...
}

解析为while (true)，因为GAMES的值从未被修改。因此，后面的任何代码(在您的情况下，doubleprobabilityOfWin=wins/(wins+loses);)都被视为无法访问。
