javafx绑定/循环问题

好吧,我正在学习javafx的激情课程,有一个问题我似乎想不出来。

这和这个问题类似-

Why doesn't this "binding" code work as expected in JavaFX?

def numbers = [1..10];
var currentNumber = 0;    

for (currentNumber in numbers){
var evenOrOdd = bind if (numbers[currentNumber] mod 2 == 0)
    "----{numbers[currentNumber]} is an even number"
    else "----{numbers[currentNumber]} is an odd number";
println("{evenOrOdd}");
}

我的输出-

----2 is an even number
----3 is an odd number
----4 is an even number
----5 is an odd number
----6 is an even number
----7 is an odd number
----8 is an even number
----9 is an odd number
----10 is an even number
----0 is an even number

我现在遇到的问题是,它看起来运行正常,只是它不将1显示为奇数,然后在10之后加上0。我花了一段时间来完成这个项目,似乎不知道它是如何/为什么这样做的。

我可以让它在没有任何约束的情况下运行良好,所以不确定这是否是导致我问题的原因。

有什么想法吗?
