有人可以帮我写代码吗?如何在文本文件中搜索任何单词并计算重复的次数?

someone can help me with code? How to search in text file any word and count how many it were repeated?

例如test.txt:

For example test.txt:

public int countWord(String word, File file) {
int count = 0;
Scanner scanner = new Scanner(file);
while (scanner.hasNextLine()) {
    String nextToken = scanner.next();
    if (nextToken.equalsIgnoreCase(word))
