方法一：Python代码示例

import re

def count_words(filename):
    """统计文件中每个单词出现的次数"""
    with open(filename, encoding='utf-8') as f:
        text = f.read()
        words = re.findall(r'\w+', text.lower())
        return {word: words.count(word) for word in words}

def compare_word_counts(file1, file2):
    """比较两个文件的单词数，并考虑单词出现次数"""
    count1 = count_words(file1)
    count2 = count_words(file2)
    for word in set(count1.keys()) | set(count2.keys()):
        if word in count1 and word in count2:
            if count1[word] > count2[word]:
                print(f"{word}: {count1[word]} > {count2[word]}")
            elif count1[word] < count2[word]:
                print(f"{word}: {count1[word]} < {count2[word]}")
            else:
                print(f"{word}: {count1[word]} = {count2[word]}")
        elif word in count1:
            print(f"{word}: {count1[word]} > 0")
        else:
            print(f"{word}: 0 < {count2[word]}")

使用示例：

compare_word_counts('file1.txt', 'file2.txt')

方法二：Java代码示例

import java.io.File;
import java.io.FileNotFoundException;
import java.util.HashMap;
import java.util.Scanner;

public class CompareWordCounts {
    public static void main(String[] args) {
        String file1 = "file1.txt";
        String file2 = "file2.txt";

        HashMap count1 = countWords(file1);
        HashMap count2 = countWords(file2);

        for (String word : count1.keySet()) {
            if (count2.containsKey(word)) {
                int c1 = count1.get(word);
                int c2 = count2.get(word);
                if (c1 > c2) {
                    System.out.printf("%s: %d > %d%n", word, c1, c2);
                } else if (c1 < c2) {
                    System.out.printf("%s: %d < %d%n", word, c1, c2);
                } else {
                    System.out.printf("%s: %d = %d%n", word, c1, c2);
                }
                count2.remove(word);
            } else {
                int c1 = count1.get(word);
                System.out.printf("%s: %d > 0%n",
