在未排序的字符串数组中搜索(Searching in unsorted string array)

在未排序的字符串数组中搜索(Searching in unsorted string array)

我有这个字符串数组

private static String[] colorsArray = { "#bde876", "#ff8581", "#ffc472", "#faed75", "#a8c9e5", "#999999", "#e3a8e5", "#dddddd", "#fc603c", "#ffcc00", "#74e8d4", "#3cd6fc" };

然后我有这个方法

public static int getColorByString(String color) { return Arrays.binarySearch(colorsArray, color); }

当我调用getColorByString("#ff8581"); 它给了我-13结果。

如果我理解得很好，这意味着该元素不包含在我的数组中。

我究竟做错了什么？ 我怎样才能使它工作？

编辑

我刚刚意识到数组必须排序。 问题是我无法对其进行排序，因为我需要将字符串映射到特定索引。

所以现在问题变成了，是否存在执行线性搜索的方法或是否必须编写它？

I have this array of strings

private static String[] colorsArray = { "#bde876", "#ff8581", "#ffc472", "#faed75", "#a8c9e5", "#999999", "#e3a8e5", "#dddddd", "#fc603c", "#ffcc00", "#74e8d4", "#3cd6fc" };

Then I have this method

public static int getColorByString(String color) { return Arrays.binarySearch(colorsArray, color); }

When I call getColorByString("#ff8581"); it gives me -13 as result.

If I understood well, it means that the element is not contained in my array.

What am I doing wrong? How can I make it work?

EDIT

I just realized the array has to be sorted. The problem is I can't sort it, because I need to map the strings to a specific index.

So now the question becomes, is there any method that performs a linear search or do I have to write it?

怎么样

Arrays.<String>asList(colorArray).indexOf("#ff8581");

How about

Arrays.<String>asList(colorArray).indexOf("#ff8581");
