我试图找出为什么我的程序似乎没有进入我的一个方法：assignKennel（）。相反，它不断要求更多的输入，即使在while循环中有更多的事情要做。任何建议将不胜感激。我不知道要包括什么，所以这就是我所拥有的一切。

它确实运行assignKennel()。如果你在那里放一个System.out.println()语句来验证该方法是否运行，你会看到它。问题不在于那种方法;每个方法都在运行。
您的问题出在displayKennel()。它没有做任何事情。 areKennelsFull()评估为false，inputDogID==9999也是如此（假设输入了其他ID）。我猜测areKennelsFull()在输入有效ID之后应该评估为true，因此问题的根本原因很可能是areKennelsFull()或{{1}错误地在assignKennels()中的某处分配值。

它确实输入了该例程，但我看到的一个问题是你超出了数组索引。对于应该读作“count＆lt; 8”（删除“=”）的语句，3中的条件为“count＆lt; = 8”。当它试图使用索引8时，它会发生轰炸，因此程序无法正常完成。数组的索引从0到7，因此8无效。
