博客園http://www.cnblogs.com/duasonir/p/5297338.html

2. Platform：Eclipse

Language：Java

3. Bug：暫時還沒有bug

4. Function improvement：所找的代碼的各個擴展已經很全面，主函數用string字符串接受用戶輸入，並分解成參數數組和文件地址。編寫BaseCount()函數實現對文件的讀操作，逐行統計統計字符數，並記錄行數，同時使用StringBuffer類記錄文件中所有的信息。最後一起統計詞數，避免在逐行計詞時，把標點計為一詞。編寫Response()函數根據用戶輸入的參數輸出信息，這裏程序不管用戶輸入的參數是什麽，都在讀取文件的時候把所有信息都記錄下來並保存，用戶輸入的參數裏有什麽輸出什麽。

5. Implementation：可實現

6.代碼如下：

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;

	public static void main(String[] args) {

			 Scanner s = new Scanner(System.in);
			 shuru = s.nextLine();
			 String[] arrMessSplit = shuru.split(" ");
			 int iMessLength = arrMessSplit.length;
			 strLong = new String[iMessLength - 1];
			 File = arrMessSplit[iMessLength - 1];
			 CountNumber();
			 for (int i = 0; i < strLong.length; i++) {
