问题:计算一个文件中的字符数，单词数，行数

我自己的实现如下:
package homeWork6;

import java.util.Scanner;
import *;

public class T0822 {     
    private static BufferedReader reader;

    public static void main(String[] args) throws Exception {
    //统计一个文件中有好多的字符数，单词数，以及行数
    static void q2() throws Exception{
        File file = new File("text2.txt");
               
        FileInputStream file1 = new FileInputStream(file);
        InputStreamReader in = new InputStreamReader(file1);   
        reader = new BufferedReader(in);
        
        String line = null;
        int charCount = 0;
        int wordCount = 0;
        int hangCount = 0;
        
        while((line = reader.readLine()) != null) {           
            if(!line.equals("")) { //一行什么都没有
                //计算字符个数
                charCount += line.length();
               
                //计算单词个数
                String[] str = line.split(" ");
                wordCount += str.length;
               
                //计算行数
                hangCount++;                        
            }                       
        }
        System.out.println("文件中的字符个数为:" + charCount);
        System.out.println("文件中的单词个数为:" + wordCount);
        System.out.println("文件中的行数个数为:" + hangCount);     
    }
}
计算结果的单词数和行数有错误，但是我觉得我的想法没有错
