JAVA实现文件遍历

不知道为什么偏爱于文件遍历

package xiya;

import java.io.*;
import java.util.*;

public class WinSearch {
	private String fileName[];
	private int count = 0;
	WinSearch(){
		fileName = new String[100000];
	};
	
	void winSearch(File file){
		
		if(file.isDirectory()){
			System.out.println("<" + file.getAbsolutePath() + ">");
			fileName[count++] = "<" + file.getAbsolutePath() + ">";
			String filename[] = file.list();
			for(int i = 0; i < filename.length; i++){
				File temp = new File(file.getAbsoluteFile() + "\\" + filename[i]);
				if(temp.isDirectory()){
					winSearch(temp);
				}
				else{
					System.out.println(filename[i]);
					fileName[count++] = filename[i];
				}
			}
		}
		else{
			System.out.println(file);
			fileName[count++] = file.toString();
		}
	}
	public static void main(String[] args) {
		
//		Scanner cin = new Scanner(System.in);
//		String string = cin.next();
//		File file = new File(string);
//		WinSearch win = new WinSearch();//命令行输入
//		win.WinSearch(file);
		
		WinSearch win = new WinSearch();  //缓冲区输入
		
		File in = new File("D:\\JAVA\\test\\文件遍历\\in.txt");
		File out = new File("D:\\JAVA\\test\\文件遍历\\out.txt");
		try{	
			FileReader inOne = new FileReader(in);
			BufferedReader inTwo = new BufferedReader(inOne);
			String string = null;
			while((string=inTwo.readLine()) != null){
				win.winSearch(new File(string));
			}
			inOne.close();
			inTwo.close();
			
			FileWriter outOne = new FileWriter(out);
			BufferedWriter outTwo = new BufferedWriter(outOne);
			for(int i = 0; i < win.count; i++){
				outTwo.write(win.fileName[i]);
				outTwo.newLine();
			}
			outOne.flush();//旧版本中没有刷新缓冲区，抛出异常=。=
			outTwo.flush();
			outOne.close();
			outTwo.close();
		}
		catch (IOException e) {
			System.out.println(e);
		}
	}

}
