[英]This code is getting unreachable code, and I'm not sure why
抱歉有大量代码,但我不知道为什么
int timesWon;
在第 90 行出现无法访问的代码错误。放在第 90 行的任何内容都是无法访问的代码,这意味着它之后的任何内容都不可读。
这是我为任务进行掷骰子游戏的代码:
package homework2_3;
import java.security.*;
public class Craps
{
static enum score
{
win, lose
}
public static void main(String[] args)
{
//random Number for a dice roll
SecureRandom random = new SecureRandom();
//ints for the totals on the two dice
int dice1;
int dice2;
//array for times won/lost
score[] total = new score[1000000];
//int for the score of the first throw, if it was not an imediate win or loss
int throw1Score = 0;
//count how many times a win or loss happened at each roll from 1-21
int[] rollWon = new int[22];
int[] rollLost = new int[22];
//loop for each game from 1-1000000
for(int indexGame = 1; 1 <= 1000000; indexGame++)
{
//loop for each throw within a game
for(int indexThrow = 1; total[indexGame] != score.win || total[indexGame] != score.lose; indexThrow++)
{
//get the total of blips on the dice
dice1 = random.nextInt(6) + 1;
dice2 = random.nextInt(6) + 1;
//check if the throw total in throw 1
if(indexThrow == 1)
{
//check if throw 1 is an instant win
if((dice1 + dice2) == 7 || (dice1 + dice2) == 11)
{
total[indexGame] = score.win;
rollWon[indexThrow]++;
}
//check if throw 1 is an instant loss
else if((dice1 + dice2) == 2 || (dice1 + dice2) == 3 || (dice1 + dice2) == 12)
{
total[indexGame] = score.lose;
rollLost[indexThrow]++;
}
//get your "point"
else
{
throw1Score = dice1 + dice2;
}
}
//anything other than throw 1
else
{
//check if you "made your point"
if((dice1 + dice2) == throw1Score)
{
total[indexGame] = score.win;
if(indexThrow <= 20)
{
rollWon[indexThrow]++;
}
else if(indexThrow > 20)
{
rollWon[21]++;
}
}
//check if you rolled a 7 (lost)
else if((dice1 + dice2) == 7)
{
total[indexGame] = score.lose;
if(indexThrow <= 20)
{
rollLost[indexThrow]++;
}
else if(indexThrow > 20)
{
rollLost[21]++;
}
}
}
}
}
//ints to add up all the wins and losses in the array of scores
int timesWon;
int timesLost;
//loop for the adding
for(int winLossCheck = 1; winLossCheck <= 1000000; winLossCheck++)
{
if(total[winLossCheck] == score.win)
{
timesWon++;
}
if(total[winLossCheck] == score.lose)
{
timesLost++;
}
}
//print the total times you won/lost
System.out.println("you won " + timesWon + " times, and you lost " + timesLost + " times");
}
}
据我所知,一切在逻辑上和语法上都是正确的。
在此先感谢您的帮助!
1 <= 1000000
始终为true
您有一个 for 循环,其中条件为1 <= 1000000
。 此循环不会退出,从而使循环后的所有代码都无法访问。 将条件更改为代码将退出的内容。
例如:
for(int i = 1; i<=10; i++) {
System.out.println(i);
}
此代码将打印出 1-10 之间的整数。 但是,如果我创建另一个 for 循环,其条件始终为真,例如 0<7。 由于循环不会结束,它之后的所有代码都无法访问。 更改您的 for 循环以使其条件不总是为真,因此程序将继续。
