复制文件，仅仅是指定的某个文件，比较简单，但是某个文件夹，就有点技巧

public static void copyFolder(String oldPath, String newPath) {try {(new File(newPath)).mkdirs(); //确保新路径的文件夹存在File a = new File(oldPath);String[] file = a.list();File temp = null;for (int i = 0; i < file.length; i++) {if (oldPath.endsWith(File.separator)) {temp = new File(oldPath + file[i]);} else {temp = new File(oldPath + File.separator + file[i]);}if (temp.isFile()) {FileInputStream input = new FileInputStream(temp);FileOutputStream output = new FileOutputStream(newPath+ "/" + (temp.getName()).toString());byte[] b = new byte[1024];int len;while ((len = input.read(b)) != -1) {output.write(b, 0, len);}output.close();input.close();}if (temp.isDirectory()) {//如果是子文件夹copyFolder(oldPath + "/" + file[i], newPath + "/" + file[i]);}}} catch (Exception e) {System.out.println("复制文件夹出错" + e.getMessage());}}

测试

public static void main(String[] args) throws Exception {copyFolder("C:\\1", "D:\\1");}
