Java-比较Sentinel值字符串的问题

我的while循环和sentinel值没有注册有一个简单的问题。我已经得出结论，我的问题在于while循环，或者可能是用户输入的分配。我的程序的基本思想是我有一个带有字符串值的2D数组。我正在尝试根据用户输入访问这些内容。我询问用户想要什么状态，然后我的程序将返回状态、状态鸟和状态花。在main类中，我需要请求用户输入，使用while循环，以及我选择为“none”的sentinel值。我希望用户能够继续询问状态，直到他们在命令行中输入none。我在代码中加入了注释，以帮助尝试和理解我正在尝试做的事情。我的问题是：为什么我的哨兵价值观不起作用？即使我没有输入任何内容，循环也会永远持续。为什么我的代码即使给程序一个合法的输入，比如“Texas”，也不返回输出值
