Question

for (a = 0; a < filename; a++) {
    Map<Double,String> m = new HashMap<Double,String>();

    String pre = "abc";
    String post = ".txt";
    for (int ii = 0; ii < 11; ii++) {
        m.put(similarityScore[a],pre + a + post + '\n');
    }
    SortedSet<Double> set = new TreeSet<Double>(m.keySet());
    for (Double d : set) {
        System.out.println(d + " " + m.get(d));
    }
    }

示例输出：

The resulting similarity score of the query how [INITIAL OUTPUT]

abc0.txt = 0.5773502691896258

abc1.txt = 0.5773502691896258

abc2.txt = 0.5773502691896258

abc3.txt = NaN

我如何使文本文件与相似性得分合并，甚至排序？在另一种意义上，即使在排序之后，输出显示每个单独的文本文件也遵循其个体分数。

Answer 1

使用集合和比较器听起来最简单（或最直接）。

将值放在Map中，然后对double进行排序。这甚至可能是自然排序顺序，因此您不必编写比较器。

Map<Double,String> m = new HashMap<Double,String>();

String pre = "abc";
String post = ".txt";
for (int ii = 0; ii < 10; ii++) {
    m.put(Math.random(),pre + ii + post);
}
SortedSet<Double> set = new TreeSet<Double>(m.keySet());
for (Double d : set) {
    System.out.println(d + " " + m.get(d));
}

这将返回一个已排序的输出（从低到高），您可以轻松地将其反转或以不同的方式运行。

- 编辑以使用OP的修改代码显示：

// Initialize variables
String pre = "abc";
String post = ".txt";
Map<Double,String> m = new HashMap<Double,String>();

// Add data to your map
for (int a = 0; a < filename; a++) {
   m.put(similarityScore[a],pre + a + post + '\n');
}

// sort the map keyset and print out the sorted results
SortedSet<Double> set = new TreeSet<Double>(m.keySet());
for (int ii = set.size(); ii >= 0; --ii) {
   System.out.println(set.get(ii) + " " + m.get(d));
}

如何合并排序值以及与值一起出现的名称？
