java - وجلب - كيفية البحث على برنامج excel

استخدام مجموعة MultiSet من مكتبة جوافة جوجل .

Multiset<String> wordsMultiset = HashMultiset.create();
Scanner scanner = new Scanner(fileName);
while (scanner.hasNextLine()) {
    wordsMultiset.add(scanner.nextLine());
}
for(Multiset.Entry<String> entry : wordsMultiset ){
     System.out.println("Word : "+entry.getElement()+" count -> "+entry.getCount());
}

حاول استخدام java.util.Scanner.

public int countWords(String w, String fileName) {
int count = 0;
Scanner scanner = new Scanner(inputFile);
scanner.useDelimiter("[^a-zA-Z]"); // non alphabets act as delimeters
String word = scanner.next();
if (word.equalsIgnoreCase(w))
    count++;
   return count;
}

يمكنك قراءة سطر ملف النص سطرا. أفترض أن كل سطر يمكن أن يحتوي على أكثر من كلمة واحدة. لكل خط، تتصل:

String[] words = line.split(" "); 
for(int i=0; i<words.length; i++){
   if(words[i].equalsIgnoreCase(searhedWord))
         count++;
}

    int counLine = 0;

    try{

            stringLine = stringLine + s;
            stringLine = stringLine + " ";/*Add space*/
            counLine ++;
        }
        System.out.println(stringLine);

        stringArray = stringLine.split(" ");
        arrayLength = stringArray.length;
