将包中的所有java源文件代码写入一个txt文件中

因为工作原因需要将所有的java代码拷贝出来贴到一个word文档中。

不多说直接贴出代码：

package com.ucit;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.util.ArrayList;
import java.util.List;

public class Counter {


	public static List<File> files = new ArrayList<File>();
	
	public static BufferedWriter out ;
	public static void main(String[] args) throws Exception, FileNotFoundException {
		// TODO Auto-generated method stub
		//定义或去java源文件的路径
		getAllJavaFiles(new File("D:\\eclipse3.6\\eclipse\\workspace\\Yx_lg2.0\\apps\\cn\\net\\comsys\\ut\\apps"));
		File to = new File("d:\\tmp.txt");
		BufferedWriter out = new BufferedWriter(new OutputStreamWriter(
				new FileOutputStream(to), "UTF8"));
		for (File file : files) {
			//读文件
			BufferedReader in = new BufferedReader(new InputStreamReader(
					new FileInputStream(file), "UTF8"));
			String str;
			//读出一行写一行
			while ((str = in.readLine()) != null) {
				out.write(str);
				out.newLine();
				out.flush();
			}
			in.close();
		}
		out.close();
	}
	
	//递归查找文件，ps:加入一些判断的话可以查找出你需要的文件
	public static void getAllJavaFiles(File dir){
		File[] fs = dir.listFiles();
		for (int i = 0; i < fs.length; i++) {
			if (fs[i].isDirectory()) {
				try {
					getAllJavaFiles(fs[i]);
				} catch (Exception e) {
					e.printStackTrace();
				}
			
			}else
				files.add(fs[i]);
		}
	}
	
}
