java中将文件夹里面的文件复制到指定的文件夹（java IO）

//现在制定路径下创建名称为左侧的文件夹

public class Copy {

	public static void main(String[] args) {
		 //原始文件地址
        File srcFolder = new File("C:\\Users\\Pei\\Desktop\\测试复制");
        //原始文件名
        String srcFloderName = srcFolder.getName();
        System.out.println(srcFloderName);
        //要复制到的文件
        File desFolder = new File("C:\\Users\\Pei\\Desktop\\左侧", srcFloderName);
        //如果要复制到的文件没有这个文件夹，就创建一个
        if (!desFolder.exists()){
            desFolder.mkdir();
        }
        try {
			copyFolder(srcFolder,desFolder);
		} catch (IOException e) {

			e.printStackTrace();
		}

	}
	//复制文件夹
    private static void copyFolder(File srcFolder, File desFolder) throws IOException {
        //遍历原始文件夹里面的所有文件及文件夹
        File[] files = srcFolder.listFiles();
        for (File srcFile : files) {
            //如果是文件夹
            if (srcFile.isDirectory()){
                //在新的文件夹内创建一个和srcFile文件夹同名文件夹，然后再递归调用，判断文件夹里面的情况，然后做出相应处理
                String srcFileName = srcFile.getName();
                File newFolder = new File(desFolder, srcFileName);
