我必須閱讀交流代碼并分析代碼。比如代碼中函數(shù)的數(shù)量，比如操作符的數(shù)量。我嘗試了很多，但我對(duì) Java 編程語言很陌生，我沒有發(fā)生。我閱讀了很多主題，試圖用掃描儀類來做，但沒有發(fā)生。你能幫助我嗎？public static void main(String[] args) throws IOException {     File file = new File("C:\\main.c");     FileInputStream fileStream = new FileInputStream(file);     InputStreamReader input = new InputStreamReader(fileStream);     BufferedReader reader = new BufferedReader(input);     String line;     while((line = reader.readLine()) != null)     {         String[] operatorsNumbers=line.split("+");        int operators=operatorsNumbers.length;    }     System.out.println("number of operators" + operators );}
