用java编写程序，统计一个文本文件中的字符（包括空格）数、单词数和行的数目。

Question

我是对java了解并不多，有没有最浅显的方法写这个程序，该怎么写

Answer 1

import java.io.*;
public class A {
    public static void main(String args[]) throws IOException {
        File f1 = new File("test.txt");//这里是文本文件的路径
        BufferedReader fis = new BufferedReader(new FileReader(f1));
        int charCount = 0;
        int wordsCount = 0;
        int lineCount = 0;
        String aLine = fis.readLine();
        while (aLine != null) {
            charCount = charCount + aLine.length();
            String[] words = aLine.split("[,.]");
            wordsCount = wordsCount + words.length;
            lineCount = lineCount + 1;
            aLine = fis.readLine();

        }
        System.out.println("charCount = " + charCount);
        System.out.println("wordsCount = " + wordsCount);
        System.out.println("lineCount = " + lineCount);
    }

}
