有人可以帮助我的代码？
如何在文本文件中搜索任何单词并计算重复的数量？

例如test.txt：

  hi 
 hola 
 hey 
 hi 
 bye 
 hoola 
 hi 
  

如果我想知道在test.txt中重复多少次Hi程序必须说3次重复

我希望你能理解我想要的，谢谢你的答案。

解决方案

  public int countWord（String word，File file）{
 int count = 0; 
扫描仪scanner =新扫描仪（文件）; 
 while（scanner.hasNextLine（））{
 String nextToken = scanner.next（）; 
 if（nextToken.equalsIgnoreCase（word））
 count ++; 
} 
 return count; 
} 
  

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

For example test.txt:

hi
hola
hey
hi
bye
hoola
hi

And if I want to know how many times are repeated in test.txt word "Hi" program must say "3 times repeated"

I hope you understood what I want, thank you for answers.

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))
    count++;
}
return count;
