java 实现文件夹的拷贝实例代码

这里就直接上代码，废话不多说，很简单很实用。

实例代码：

import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;public class CopyFile { public static void copy(String sourceFile , String targetFile) throws Exception{ FileInputStream in = null; FileOutputStream out = null; try{ in = new FileInputStream(new File(sourceFile)); out = new FileOutputStream(new File(targetFile)); int c; while ((c = in.read()) != -1 ){ out.write(c); } } finally{ if (in != null){ in.close(); } if(out != null){ out.close(); } } } public static void main(String[] agrs) throws Exception{ String filedir = "./tupu0"; String targetDir = "./MovieList/"; File directory = new File(filedir); File[] fileList = directory.listFiles(); for(int i=0; i<fileList.length; i++){ String sourceFile = "./tupu0/" + fileList[i].getName() + "/" + fileList[i].getName() +".txt"; String targetFile = targetDir + fileList[i].getName(); System.out.println(fileList[i].getName()); copy(sourceFile, targetFile); } }}
