Java文件操作

[align=left]写了个Java操作文件的简单例子，希望给需要帮助的兄弟提供点儿帮助，同时也希望大家给予批评指正。
文件操作类，代码如下：

package org.coolyongzi;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.log4j.LogManager;
import org.apache.log4j.Logger;


public class FileTools {
	private static final String SPECIAL_FILE_STYLE_PICTURECACHE = "Thumbs.db";
	public static final Logger logger = LogManager.getLogger(FileTools.class);

	public FileTools()
	{

	}
	/*
	 * @discription:Delete a folder
	 * @param:dirPath String
	 * @return boolean
	 */
	public static boolean deleteDirectory(String dirPath,boolean deteDirRoot)
	{
		File parentFile = new File(dirPath);
		File[] chirenFile = null;
		if(parentFile.exists() && parentFile.isDirectory())
		{
				chirenFile = parentFile.listFiles();
				for (int i = 0; i < chirenFile.length; i++) {
					if(!chirenFile[i].isDirectory())
					{
						chirenFile[i].delete();
					}
					else
					{
						deleteDirectory(chirenFile[i].getAbsolutePath(),true);					
						chirenFile[i].delete();
					}
				}
				if(deteDirRoot)
				{
					parentFile.delete();
				}

				return true;		
		}
		else
		{
			FileTools.logger.error("The Floder Is Not Exist!");
			return false;
		}
	}

	/*
	 * @discription:Copy Folder
	 * @param:sourceFilePath String,targetFilePath String
	 * @return boolean
	 */
	public static boolean copyDirectory(String sourceFilePath,String targetFilePath) throws IOException
	{
		File sourceFile = new File(sourceFilePath);
		File targetFile = new File(targetFilePath);

		if(!targetFile.exists())
		{
			targetFile.mkdir();
		}

		File[] sourceChirenFile = null;
		FileInputStream fileInputStream = null;
		FileOutputStream fileOutputStream = null;
		FileTools.logger.debug("Copy "+sourceFile.getName()+" Floder Start......");
		if(sourceFile.exists() && sourceFile.isDirectory())
		{
			sourceChirenFile = sourceFile.listFiles();
			for (int i = 0; i < sourceChirenFile.length; i++) {
				File tempFile = null;

				if(!sourceFilePath.endsWith(File.separator))
				{
					tempFile = new File(targetFilePath+File.separator+sourceChirenFile[i].getName());
				}
				else
				{
					tempFile = new File(targetFilePath+sourceChirenFile[i].getName());
				}
				if(!FileTools.SPECIAL_FILE_STYLE_PICTURECACHE.equalsIgnoreCase(sourceChirenFile[i].getName()))
				{
					if(!sourceChirenFile[i].isDirectory())
					{
						fileInputStream = new FileInputStream(sourceChirenFile[i]);
						fileOutputStream = new FileOutputStream(tempFile);
						byte[] b = new byte[1024];
						FileTools.logger.debug("Copy "+sourceChirenFile[i].getName()+" File Start......");
					    while(fileInputStream.read(b)!=-1)
					    {
					    	fileOutputStream.write(b);
					    }
					    FileTools.logger.debug("Copy "+sourceChirenFile[i].getName()+"  File End!");
					    fileInputStream.close();
					    fileOutputStream.close();	
					}
					else
					{
						copyDirectory(sourceFilePath+File.separator+sourceChirenFile[i].getName(),
								      targetFilePath+File.separator+sourceChirenFile[i].getName());
					}
				}

			}
			FileTools.logger.debug("Copy "+sourceFile.getName()+" Floder End!");
			return true;
		}
		else
		{
			FileTools.logger.error("The Floder Is Not Exist!");
			return false;
		}
	}
}

Junit测试类

package org.coolyongzi.testcase;

import java.io.IOException;

import org.coolyongzi.FileTools;

import junit.framework.TestCase;

public class FileToolsTest extends TestCase {

	protected void setUp() throws Exception {
		super.setUp();
	}

	protected void tearDown() throws Exception {
		super.tearDown();
	}

	public void testDeleteDirectory() 
	{
		FileTools.deleteDirectory("F:/复件 图片",false);
	}

	public void testCopyDirectory()
	{
		try {
			FileTools.copyDirectory("F:/Game","F:/Game1");
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
