**案例介绍：**

首先需要创建一个WordsCount.txt的文本文件，在里面输入如下内容（内容自定义即可）。

然后编写以下代码并运行。

**案例代码：**

import java.io.*;
    public class WordsCount {
        
    	public static void main(String args[]) throws IOException{
        
    	 File f1 = new File("WordsCount.txt");
       	 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);
    	}
    }
