有人可以帮我找出为什么while语句不工作?循环在i = 3之后停止,但如果continueSurvey = 0则不会停止。它会运行,但如果将continueSurvey更改为O,它将不会退出循环。即使我进入进程并且我可以看到变量是0,循环继续。虽然在多条件的Java循环
import java.util.Scanner;
public class SurveyConductor
{
public static void main(String[] args)
{
Survey a = new Survey();
a.display();
a.enterQuestions();
int continueSurvey = 1;
int i = 0;
while ((continueSurvey != 0) && (i < 3))
{
for (int row = a.getRespID(); row < 3; row++)
{
System.out.println("Respondent " + (row+1) + " Please tell us how you would rate our: ");
for (int col = 0; col < 3; col++)
{
Scanner input = new Scanner(System.in);
System.out.println(a.presentQuestion(col) + ": ");
System.out.println("Enter your response (1-Strongly Disagree, 2-Disagree, 3-Neutral, 4-Agree, 5-Strongly Agree): ");
int response = input.nextInt();
if ((response < 1) || (response >5))
{
while ((response < 1) || (response > 5))
{
System.out.println("Your response must be between 1 and 5. Please try again.");
System.out.println(a.presentQuestion(col) + ": ");
System.out.println("Enter your response (1-Strongly Disagree, 2-Disagree, 3-Neutral, 4-Agree, 5-Strongly Agree): ");
response = input.nextInt();
}
}
a.logResponse(row,col,response);
System.out.println();
}
a.displaySurveyResults();
System.out.println();
System.out.println("The top rated question is Question #" + a.topRatedQuestion() + ".");
System.out.println("The bottom rated question is Question #" + a.bottomRatedQuestion() + ".");
System.out.println();
Scanner input2 = new Scanner(System.in);
System.out.println("Are there any more repondents (0 - No, 1 - Yes): ");
continueSurvey = input2.nextInt();
a.generateRespondentID();
i++;
}
}
}
}
谢谢!我最终在我的代码中放入了break语句。我尝试在for循环之外移动问题,但我需要它在下一个响应者生成之前提出问题。 –
@MichelleAnderson是的,这可能是最有意义的解决方案:)请务必接受StormeHawke的回答,因为这可以帮助其他可能有类似问题的人。 – Jordan
