Java If Statement [英] Java If Statement

问题描述

我已经用Java编写了一些代码来测试两种解决方案的适用性。

I have written some code in Java which tests the fitness of two solutions.

我希望比较两种解决方案并保持最佳解决方案健身并丢弃另一个。

I am looking to then compare the two solutions and keep the one which has the best fitness and to discard the other.

例如：

if(fitness1 < fitness2)
    keep fitness1 and discard/ignore fitness2
else
    keep fitness2 and discard/ignore fitness1

我将如何实现这一目标？最终我希望有一个最佳健身水平的清单（大小n）。我想我必须在每次迭代中将最佳适应度添加到某种类型的列表中？

How would I go about achieving this? Eventually I hope to have a list (size n) of the best fitness levels. I imagine that I would have to add the best fitness in each iteration to a list of some type?

推荐答案

我会说，创建一个 ArrayList< Double> 以保持最佳值并使用它：

I'd say, create an ArrayList<Double> to keep the best values in and use this:

arrayList.add((fitness1 < fitness2) ? fitness1 : fitness2);

这样你就会得到一个最佳值列表。

That way you'll have a list of the best values.
