我正在尝试计算文件中的重复单词，并且我想将我的输出写入该文件
public static void main(String a[]){
MaxDuplicateWordCount mdc = new MaxDuplicateWordCount();
Map<String, Integer> wordMap = mdc.getWordCount("C:/Users/Arnoldas/Desktop/Hamletas.txt");
List<Entry<String, Integer>> list = mdc.sortByValue(wordMap);
for(Map.Entry<String, Integer> entry:list){
System.out.println(entry.getKey()+" ==== "+entry.getValue());
}
}
输出现在看起来像:
hamletui ==== 4
šmėkla ==== 2
jo ==== 2
hamletas ==== 1
danijos ==== 1
pagrindiniam ==== 1
mirusio ==== 1
princui ==== 1
herojui, ==== 1
apsireiškusi ==== 1
karalystės ==== 1
paveda ==== 1
parketas ==== 1
herojui ==== 1
žudikui ==== 1
neseniai ==== 1
omletas ==== 1
atkeršyti ==== 1
tėvo ==== 1
我想将此输出放入文件中，它应该如下所示:
| hamletui | šmėkla | jo | hamletas | danijos | pagrindiniam | ...
-------------------------------------------------------------------------------------
Hamletas.txt | 4 | 2 | 2 | 0 | 0 | 0 | ...
-------------------------------------------------------------------------------------
Other_file.txt | 0 | 0 | 6 | 3 | 4 | 1 | ...
可以这样做吗？我也想从其他文件中获取输出。 有什么想法吗？

好的。如何使用表格将其编写为 HTML 文件的示例。 输入是一个以文件名作为键的映射和一个带有计数的单词映射。 首先查看 map 中提到了哪些单词。然后它编写 HTML。 第一个表行包含所有这些单词，之后为每个文件名创建一行，其中包含单词数。
public static void main(String a[]) {
Map<String, Map<String, Integer>> wordMaps = new HashMap<>();
wordMaps.put("Hamletas.txt", new HashMap<String, Integer>());
wordMaps.get("Hamletas.txt").put("hamletui", 4);
wordMaps.get("Hamletas.txt").put("šmėkla", 2);
wordMaps.get("Hamletas.txt").put("jo", 2);
wordMaps.put("Other_file.txt", new HashMap<String, Integer>());
wordMaps.get("Other_file.txt").put("jo", 6);
wordMaps.get("Other_file.txt").put("hamletas", 3);
wordMaps.get("Other_file.txt").put("danijos", 4);
wordMaps.get("Other_file.txt").put("pagrindiniam", 1);
writeHtmlFile("example.html", wordMaps);
}
public static void writeHtmlFile(String filename, Map<String, Map<String, Integer>> wordMaps) {
// get all words that are duplicates
Set<String> words = new HashSet<>();
for (Map<String, Integer> map : wordMaps.values()) {
for (Map.Entry<String, Integer> entry : map.entrySet()) {
if (entry.getValue() > 1) {
words.add(entry.getKey());
}
}
}
try (PrintWriter out = new PrintWriter(new FileWriter(filename))) {
out.println("<!DOCTYPE html><html>");
out.println("<head><meta charset=\"utf-8\"/></head");
out.println("<body>");
out.println("<table border=\"1\">");
// write Headline
out.println("<tr>");
out.println("<td> </td>"); // empty cell
for (String word : words) {
out.println("<td>" + word + "</td>"); // empty cell
}
out.println("</tr>");
// write for all files
for (Map.Entry<String, Map<String, Integer>> fileWordMap : wordMaps.entrySet()) {
out.println("<tr>");
out.println("<td>" + fileWordMap.getKey() + "</td>"); // filename
Map<String, Integer> wordMap = fileWordMap.getValue();
for (String word : words) {
out.println("<td align=\"right\">" + (wordMap.containsKey(word) ? wordMap.get(word) : 0) + "</td>"); // number per
// word or 0
}
out.println("</tr>");
}
out.println("</table>");
out.println("</body>");
out.println("</html>");
} catch (IOException e) {
}
}
