我在初学者Java类中,对于一个项目,我需要计算一个条件在循环内部循环返回TRUE(correctGuess)或FALSE(incorrectGuess)的次数。我遇到的问题是,内循环中递增的变量在循环重复时不会保持其递增的值。因此,外部while循环的条件永远不会错误。我是编程新手,我无法找到解决方案。在这个愚蠢的问题上提前感谢你的时间,如果有任何问题,我会很高兴做一个更好的解释。代码如下所示:
int incorrectGuess = 0;
int correctGuess = 0;
while(incorrectGuess < 6 && correctGuess < WORD_LENGTH) {
//Gets the users first guess
System.out.print("Please guess a letter [A-Z]: ");
letterGuessed = keyboard.nextLine();
for (int i = 0; i < WORD_LENGTH; i++){
char value = wordLetterArray[i];
String letterArray_value = String.valueOf(value);
if(letterGuessed.equals(letterArray_value)){
++correctGuess;
}
else
System.out.println("Bad comparison!");
if(i == WORD_LENGTH)
++incorrectGuess;
}
}
答案 0 :(得分:1)
看起来您可能需要重新设计整个算法,但我可以告诉您永远循环的主要问题是什么:
// Seems legit
while(incorrectGuess < 6 && correctGuess < WORD_LENGTH) {
// Still seems legit
for (int i = 0; i < WORD_LENGTH; i++)
// Well, there's a problem, i will never be equal to word length
//because a condition of the for loop is i < WORD_LENGTH
if(i == WORD_LENGTH)
++incorrectGuess;
同样,我觉得你需要重新设计你的整个算法,但是如果你想让它继续下去,只需从for循环中取出不正确的Guess增量线。这将为您提供预期的结果:
for (int i = 0; i < WORD_LENGTH; i++){
char value = wordLetterArray[i];
String letterArray_value = String.valueOf(value);
if(letterGuessed.equals(letterArray_value)){
++correctGuess;
}
else {
System.out.println("Bad comparison!");
}
}
incorrectGuess++;
