我在下面运行一个循环。它会自动跳过第一次运行并给我一个答案"invalid entry"

Question

我是Java编程的新手。几天来我一直在试图解决这个问题。第一个循环跳过 if 语句并给我"无效条目"，后续运行很好。我看过很多视频，读过多个问题/答案，但仍然无法弄清楚。

任何帮助或提示将不胜感激。谢谢

很抱歉没有发布图片而不是代码。

我的代码

包5级;

import java.util.Scanner;

公开课练习 {

public static void main(String[] args) {
Scanner input = new Scanner(System.in);

System.out.println("Number of loops");
int numberOfRuns=input.nextInt();

for(int i=0;i<=numberOfRuns;i++) {
String month;
System.out.println("What month were you born in?");
month=input.nextLine();
if(month.equalsIgnoreCase("December")||month.equalsIgnoreCase("January")||month.equalsIgnoreCase("February")) {
System.out.println("You were born in Winter");
}else if(month.equalsIgnoreCase("March")||month.equalsIgnoreCase("April")||month.equalsIgnoreCase("May")){
System.out.println("You were born in Spring");
}else if(month.equalsIgnoreCase("June")||month.equalsIgnoreCase("July")||month.equalsIgnoreCase("August")) {
System.out.println("You were born in Summer");
}else if(month.equalsIgnoreCase("September")||month.equalsIgnoreCase("October")||month.equalsIgnoreCase("November")) {
System.out.println("You were born in fall");
}else {
System.out.println("invalid entry");
}

}

}

}

跳过循环出现问题的原因是下一行被跳过了。 这是一个行终止问题，您应该检查下一行是否包含任何数据，如果没有，则可以将 for 重置为上次迭代。
